wl1271 on sdmmc2

Hi all,

I have a board that has a wl1271-tiwi-ble chip connected on SDMMC2A sdio. I’ve managed to bring-up the sdio interface and now I’m trying to enable it in the board-ardbeg-sdhci.c board file. There’s seem to already be support for another sdio wifi, but now I have to port the wl1271 to it’s place. I’ve used a porting guide for a ‘similar’ platform, but I haven’t managed to make it work. To be honest I can’t find a way to ‘connect’ the wl1271 platform data (wl12xx_platform_data) to tegra_sdhci_device1.

This is my code:

In all other examples I’ve seen there’s a point that the wifi platform data can be assigned somehow to the wanted mmc, but I can’t find a way to do that on tegra. All I’ve managed is to have a /sys/devices/platform/wl1271_wlan.1 device but I can’t do anything with that.

Does anybody managed to do this?

Thanks.

I’ve forgot to say that I’ve already enabled in the kernel all the necessary config flags for wl1271.

I still haven’t managed to make this work.
I’m stuck in the point that I have to connect these interfaces together (sdmmc and wl127).

The tegra_sdhci_platform_data struct doesn’t seem to have any entry point to pass a struct for an sdio wifi interface and also the same goes for. wl12xx_platform_data.

struct wl12xx_platform_data {
	int (*set_power)(int power_on);
	int (*set_carddetect)(int val);
	/* SDIO only: IRQ number if WLAN_IRQ line is used, 0 for SDIO IRQs */
	int irq;
	bool use_eeprom;
	int board_ref_clock;
	int board_tcxo_clock;
	unsigned long platform_quirks;
	bool pwr_in_suspend;
};
struct tegra_sdhci_platform_data {
	int cd_gpio;
	int wp_gpio;
	int power_gpio;
	int is_8bit;
	int pm_flags;
	int pm_caps;
	int nominal_vcore_mv;
	int min_vcore_override_mv;
	int boot_vcore_mv;
	unsigned int max_clk_limit;
	unsigned int ddr_clk_limit;
	unsigned int tap_delay;
	unsigned int trim_delay;
	unsigned int ddr_trim_delay;
	unsigned int uhs_mask;
	struct mmc_platform_data mmc_data;
	bool power_off_rail;
	bool en_freq_scaling;
	bool cd_wakeup_incapable;
	bool en_nominal_vcore_tuning;
	unsigned int calib_3v3_offsets;	/* Format to be filled: 0xXXXXPDPU */
	unsigned int calib_1v8_offsets;	/* Format to be filled: 0xXXXXPDPU */
	bool disable_clock_gate; /* no clock gate when true */
	u32 cpu_speedo;
	unsigned char default_drv_type;
};

The only hope in the tegra_sdhci_platform_data struct seems to be the mmc_platform_data struct

struct mmc_platform_data {
	unsigned int ocr_mask;			/* available voltages */
	int built_in;				/* built-in device flag */
	int card_present;			/* card detect state */
	u32 (*translate_vdd)(struct device *, unsigned int);
	unsigned int (*status)(struct device *);
	struct embedded_sdio_data *embedded_sdio;
	int (*register_status_notify)(void (*callback)(int card_present, void *dev_id), void *dev_id);
};

But that it seems that only has the register_status_notify that in tegra_sdhci_platform_data0 by default the ardbeg_wifi_status_register is assigned. So I did the same for tegra_sdhci_platform_data1 which I’m using. That didn’t help either, as I also don’t have any “sd card detection”.

So now I’m stuck with a “wl1271_wlan” in my /sys/… that literally does nothing.

Any ideas?

Hi dimtass,

I do not see set_carddetect callback being initialized for the wl12xx_platform_data (in code from first post). I only see the set_power callback initialized. Can you confirm if I am missing something?

Is CONFIG_MMC_EMBEDDED_SDIO enabled for your platform? In case this is enabled you may want to double check if initialization for embedded_sdio_data0 is fine your sdio chip.

Can you enable debug prints and check if ardbeg_wifi_status_register is getting called? I am assuming you are not hitting any of the error scenarios that you already enabled check in your implementation. Please confirm if the review logs are showing you any errors. If you can share your complete kernel bootup log it may be helpful to debug the problem.

Regards.

Hi b2,

thanks for your response. I’ve made some minor progress but I get kernel Oops when I try to load the wl12xx module. I’m not using the CONFIG_MMC_EMBEDDED_SDIO flag, but I’ve also tried that without any result. Anyway, I believe that the problem is that the sdhci interface it doesn’t work in a first place.

For example, let’s say that I don’t use the wl1271 module and I just want to enable the sdhci.1 (sdmmc2) interface. That doesn’t work. I can’t get any clock from the sdmmc2 sdio interface in Linux, although I’ve set all the needed structures and registered the interface as a platform device. The same happens for the sdhci.0 (sdmmc1) interface. On the other hand sdmm3 & 4 which are enabled by default they working fine. On the other hand, in u-boot if I just enable the sdmmc1 and sdmmc2 interface in the device tree I get clocks from the sdio interfaces. In Linux, no.

Therefore, I believe that first I have to find a way to enable the sdmmc2 interface in the kernel and see a clock in the output and then I believe that also the wl12xx driver will work.

Do you know which is the right way to enable the sdmmc1 and sdmmc2 interfaces?

Anyway, the error I get now when I’m loading the wl12xx driver is the following:

Hi dimtass,

  1. I am assuming that you have not disconnected the SDMMC1 lines going to the BCM WIFI SDIO chip on Jetson-TK1 board. In such a case SDMMC1 should be working fine. Did you try this on the board before making hardware changes? Is it possible to share a picture of the hardware to help see how you have connected SDMMC2?

  2. Based on the kernel crash log driver wl12xx is not loading properly. If you can share the complete kernel boot log for the system there may be some clue to the problem.

  3. Do you know which is the right way to enable the sdmmc1 and sdmmc2 interfaces?
    I believe the enumeration of both the SDIO interfaces(SDMMC1 and SDMMC2) at sdhci level should have completed since the board files are statically linked and are not dependent on the dynamic loading of wl12xx driver. The complete kernel boot log should confirm this expectation.

  4. I do not see set_carddetect callback being initialized for the wl12xx_platform_data (in code from first post).
    Please confirm if the set_carddetect is defined now. You may refer the code to support TI Wifi SDIO chip at -
    http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=blob;f=arch/arm/mach-tegra/board-tegratab-sdhci.c;h=08320d6811858d119983222b7d68c8831bf2aa93;hb=refs/heads/rel-tegranote-r2

  5. I’ve managed to bring-up the sdio interface
    Is it possible share the SDIO interface aspects that you think are fine?

  1. Actually it’s a custom board where the sdmmc1 is the SD card, sdmmc2 is the sdio-wifi (wl1271). Unfortunately, it’s not possible to post any images but the hardware layout it’s correct and double/triple checked. Other than that, as I’ve wrote before the key point is that while in u-boot I can probe the sdio clk and that the clock is there, when the kernel loads the clock disappears.

  2. Yes, it seems it crashes and I believe that has to do with the fact it doesn’t have access to the sdio

This is the kernel log.

  1. Exactly, that’s my point. The problem doesn’t have to do -only- with the wl12xx, the root of the problem is that the sdmmc2 doesn’t work when the kernel starts. Also, the problem is that in the board-ardbeg-sdhci.c file the sdmmc2 (sdhci-tegra.1) is completely absent, so I had to add it manually. Therefore, I’ve added the following things:
  • static struct platform_device tegra_sdhci_device1
  • sdhci_resource1
  • tegra_sdhci_platform_data1
  • platform_device_register(&tegra_sdhci_device1);

Generally, sdmmc2 seems like it’s completely missing from the kernel.

  1. I haven’t implemented any card detect function, as I’m not using any sd detect pin, but I will try it. The kernel seems to recognize that there’s a wl12xx instance and tries to load the driver automatically during start-up though. Below is my code regarding only the sdmmc2 that enabled the kernel to load the driver.
static struct wl12xx_platform_data wlan_data = {
		.irq = 257,
		/* COM6 (127x) uses FREF */
		.board_ref_clock = WL12XX_REFCLOCK_38_XTAL,
		/* COM7 (128x) uses TCXO */
		.board_tcxo_clock = WL12XX_TCXOCLOCK_26,
		.set_power	= wl12xx_set_power,
};

static int wl12xx_set_power(int power_on)
{
	static int power_state;

	pr_info("Powering %s wl12xx", power_on ? "on" : "off");

	if (power_on == power_state)
		return(power_state);
	power_state = power_on;

	if (power_on) {
		/* Power up sequence required for wl127x devices */
		gpio_set_value(ARDBEG_WLAN_PWR, 1);
		usleep_range(15000, 15000);
		gpio_set_value(ARDBEG_WLAN_PWR, 0);
		usleep_range(1000, 1000);
		gpio_set_value(ARDBEG_WLAN_PWR, 1);
		msleep(70);
		/* also power-on BT */
		gpio_set_value(ARDBEG_BT_PWR, 1);
	} else {
		gpio_set_value(ARDBEG_WLAN_PWR, 0);
		/* also power-off BT */
		gpio_set_value(ARDBEG_BT_PWR, 0);
	}
	return(power_state);
}

  1. It’s true that I wasn’t clear on my first post. I’ve did the bring-up in the u-boot. It work’s in u-boot it doens’t work on linux.

Regardless, the wifi and wl1271, I would appreciate if someone can verify that the sdmmc1/sdmmc2 interfaces are working in linux and how to do that. What needs to be done to use any other sdmmc interface except the hardcoded sdmmc3 and sdmmc4?

Hi dimtass,

  1. Thank you for sharing the boot log. I see only SDMMC4 and SDMMC1 prints in the log (though the SD card is not detected).

  2. I shall review the portion about the code you shared with respect to SD card not working later. I think the default code in the file should need changes to support SD card instead of SDIO.

  3. I reviewed the code for SDMMC2 portion and do not see problems other than missing set_carddetect. The set_carddetect triggers the code to enumerate the instance hence you need to add it. Can you access the shared link to code for TI WIFI SDIO from my comment? Please refer the code and add the set_carddetect code for SDMMC2 instance instead of SDMMC1 instance.

  4. Can you update the devices.c file(in mach-tegra folder) and ensure that SDMMC2 instance is also enabled in the file? The default software implementation you received does not have SDMMC2 enabled. It may be the reason why the probe for SDMMC2 is not called.

Hi b2, thanks for your time and effort

  1. I’ve implemented the code for the set_carddetect with the following additions, but I still get the same Oops in the kernel. Other than that my code seems very similar to the one in the link.
static int wl12xx_set_carddetect(int val)
{
        pr_debug("%s: %d\n", __func__, val);
        if (wifi_status_cb)
                wifi_status_cb(val, wifi_status_cb_devid);
        else
                pr_warning("%s: Nobody to notify\n", __func__);
        return 0;
}

static struct wl12xx_platform_data wlan_data = {
		.irq = 257,
		/* COM6 (127x) uses FREF */
		.board_ref_clock = WL12XX_REFCLOCK_38_XTAL,
		/* COM7 (128x) uses TCXO */
		.board_tcxo_clock = WL12XX_TCXOCLOCK_26,
		.set_power	= wl12xx_set_power,
		.set_carddetect = wl12xx_set_carddetect,
};
  1. In devices.c I’ve already added the following things:
static struct resource sdhci_resource2[] = {
	[0] = {
		.start	= INT_SDMMC2,
		.end	= INT_SDMMC2,
		.flags	= IORESOURCE_IRQ,
	},
	[1] = {
		.start	= TEGRA_SDMMC2_BASE,
		.end	= TEGRA_SDMMC2_BASE + TEGRA_SDMMC2_SIZE-1,
		.flags	= IORESOURCE_MEM,
	},
};

Is there anything else I need to do there? I mean, what is the correct way to enable it there?

Thanks again.

Hi dimtass,

Can you confirm if the devices.c has the below lines unconditionally?

struct platform_device tegra_sdhci_device2 = {
190	.name		= "sdhci-tegra",
191	.id		= 1,
192	.resource	= sdhci_resource2,
193	.num_resources	= ARRAY_SIZE(sdhci_resource2),
194};

If above is there then can you please share the boot log you get with all the changes you made as per discussion above?

Regards

Hi b2,

I’ve already had done these changes as also I’ve had added another entry in devices.c

struct swgid_fixup tegra_swgid_fixup[] = {
...
	{ .name = "sdhci-tegra.1",	.swgids = SWGID(PPCS1) },
...

So, all the logs I’ve already posted are with these changes.

A thing that I’ve noticed is that in tegranote-r2 source the platform_device for tegra_sdhci_device1 is using the “sdhci-tegra” name instead of the “wl12xx” that I’m using.

static struct platform_device tegra_sdhci_device1 = {
	.name		= "wl12xx"
        // .name		= "sdhci-tegra", // <- tegranore-r2
	.id		= 1,
	.resource	= sdhci_resource1,
	.num_resources	= ARRAY_SIZE(sdhci_resource1),
	.dev = {
		.dma_mask = &tegra_sdhci_dmamask,
		.coherent_dma_mask = DMA_BIT_MASK(64),
		.platform_data = &tegra_sdhci_platform_data1,
	},
};

During my first tests I also had left the name as “sdhci-tegra” but the kernel couldn’t recognize any “wl12xx” device in order to load the driver. For example with the ‘.name=sdhci-tegra’, the log is the same as before, but when I’m loading the driver manually I’m getting the following.

root@mghd271-tk1:~# modprobe wlcore_sdio
root@mghd271-tk1:~# /s  modprobe wl12xx
[  145.073488] cfg80211: Calling CRDA to update world regulatory domain
root@mghd271-tk1:~# lsmod
Module                  Size  Used by
wlcore_sdio             4293  0 
wl12xx                 48426  0 
wlcore                164070  1 wl12xx
mac80211              351632  2 wl12xx,wlcore
cfg80211              348474  2 mac80211,wlcore
rfkill                  9649  1 cfg80211

So, the kernel doesn’t crush, but also when the driver is loaded it does nothing, there’s no device.
Also ‘iw dev’ doesn’t return anything. So, reading the porting guide from TI I thought that I had to change the .name of the device to “wl12xx” in order to trigger the driver. That did the trigger, but I got the kernel oops. I both cases though, I couldn’t get a clock from the sdmmc2 interface.

Below is the kernel log with all the changes we discussed in devices.c and board-ardbeg-sdhci.c and specifically I’ve made the exact changes in the board-ardbeg-sdhci.c, to meet exactly the rel-tegranote-r2 file (.name = “tegra-sdhci”).

I’ve found why sdmmc1 didn’t work. The problem was in the devicetree it should be like that

sdmmc1_clk_pz0 {
				nvidia,pins = "sdmmc1_clk_pz0";
				nvidia,function = "sdmmc1";
				nvidia,pull = <TEGRA_PIN_PULL_NONE>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_ENABLE>;
			};

But I’ve set the enable-input=<TEGRA_PIN_DISABLE>, as I believed that way it would be an output.

So, sdmmc1 seems like working now. Therefore, I’ve seen also the sdmmc2 pins and these seem to be correct but I’m posting theme here to be sure.

pk1 {
				nvidia,pins = "pk1";
				nvidia,function = "sdmmc2";
				nvidia,pull = <TEGRA_PIN_PULL_NONE>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_ENABLE>;
			};

			ph7 {
				nvidia,pins = "ph7",
								"ph4",
								"ph5",
								"ph6",
								"pi5";
				nvidia,function = "sdmmc2";
				nvidia,pull = <TEGRA_PIN_PULL_UP>;
				nvidia,tristate = <TEGRA_PIN_DISABLE>;
				nvidia,enable-input = <TEGRA_PIN_ENABLE>;
			};

Hi dimtass,
For sdmmc pins, the following can be considered as the general guidelines w.r.t pinmux settings. All data lines should have pull-ups enabled. No pull-up/pull-down for clock line. For cmd line, pull-up/pull-down depends on the device used. Please refer to section 29.7.1.3(SDMMC2A pinmux settings) in the Technical reference manual for more details.

The above settings are fine. Apart from adding the pinmux settings, you also need to remove them from unused_lowpower pins group in the dtsi file. If not, the pins might be put in low power state and device will not work.

Regarding E_INPUT, SDMMC controller has feedback clock enabled by default(29.8.2.1 - SDMMC_VENDOR_CLOCK_CNTRL_0 register). Feedback clock helps in proper sampling of data. Hence, E_INPUT has to be enabled for the pin used as SDMMC clock line.

Hi kkpavan,

thanks for the info!
The sdmmc2 pins for clk, cmd and data are in the ‘pinmux_default: common {}’ part of the pinmux.dtsi file. Other than that, if the rest are correct then there must be something, somewhere. I’ll try to debug it more and see.

thanks again!

I’ve also made the sdmmc2 to work. The problem was in that there was an entry ‘TEGRA_GPIO(K, 1)’ in tegra124-gpio.dtsi

Well, I know that this seems simple fix, but it’s really frustrating that the gpios are scattered between different files as also that it’s not clear which devices and parameters of the device-tree are really implemented and which are only hardcoded in the kernel.

Anyway, I’ve followed the code from the link that b2 has gave me.
http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=blob;f=arch/arm/mach-tegra/board-tegratab-sdhci.c;h=08320d6811858d119983222b7d68c8831bf2aa93;hb=refs/heads/rel-tegranote-r2

With this code everything compiles just fine and I don’t get kernel oops. On the other hand the kernel doesn’t seem to recognize the wl12xx module and it doesn’t try to load any driver. If I try to manually load the driver then it loads, but no device is really registered so ‘iw dev’ doesn’t return any devices. Therefore, it seems that a link between the interface and the driver is missing and this probably has to do with naming something to “wl12xx”, which kicks off the driver. I’ve tried to re-name the ‘platform_device tegra_sdhci_device1’ from ‘sdhci-tegra’ to ‘wl12xx’. This kicks the driver load but the kernel crashes. I’ve also tried to create a second device like that

static struct wl12xx_platform_data wl12xx_wlan_data = {
		/* COM6 (127x) uses FREF */
		.board_ref_clock = WL12XX_REFCLOCK_38_XTAL,
		/* COM7 (128x) uses TCXO */
		.board_tcxo_clock = WL12XX_TCXOCLOCK_38_4,
		.set_power	= wl12xx_set_power,
		.set_carddetect = wl12xx_set_carddetect,
};

static struct resource wl1271_wifi_resource[] = {
	[0] = {
		.name   = "wl1271_wlan_irq",
		.flags  = IORESOURCE_IRQ | IORESOURCE_IRQ_LOWLEVEL | IORESOURCE_IRQ_SHAREABLE,
	},
};

static struct platform_device wl1271_wifi_device = {
	.name           = "wl12xx",
	.id             = 1,
	.num_resources  = 1,
	.resource       = wl1271_wifi_resource,
	.dev            = {
		.platform_data = &wl12xx_wlan_data,
	},
};

static struct platform_device tegra_sdhci_device1 = {
	.name		= "sdhci-tegra",
	.id		= 1,
	.resource	= sdhci_resource1,
	.num_resources	= ARRAY_SIZE(sdhci_resource1),
	.dev = {
		.platform_data = &tegra_sdhci_platform_data1,
	},
};

static int __init wl12xx_wlan_init(void)
{
	int rc;
	pr_info("==== wl1271 wl12xx_set_platform_data\n");

	rc = gpio_request(WL12XX_WLAN_PWR, "wlan_power");
	if (rc)
		pr_err("WLAN_PWR gpio request failed:%d\n", rc);
	rc = gpio_request(WL12XX_WLAN_RST, "wlan_rst");
	if (rc)
		pr_err("WLAN_RST gpio request failed:%d\n", rc);
	rc = gpio_request(WL12XX_WLAN_WOW, "bcmsdh_sdmmc");
	if (rc)
		pr_err("WLAN_WOW gpio request failed:%d\n", rc);
	rc = gpio_request(WL12XX_BT_PWR, "bt_power");
	if (rc)
		pr_err("BT_PWR gpio request failed:%d\n", rc);

	rc = gpio_direction_output(WL12XX_WLAN_PWR, 0);
	if (rc)
		pr_err("WLAN_PWR gpio direction configuration failed:%d\n", rc);
	rc = gpio_direction_output(WL12XX_WLAN_RST, 0);
	if (rc)
		pr_err("WLAN_RST gpio direction configuration failed:%d\n", rc);

	rc = gpio_direction_input(WL12XX_WLAN_WOW);
	if (rc)
		pr_err("WLAN_WOW gpio direction configuration failed:%d\n", rc);
	rc = gpio_direction_input(WL12XX_BT_PWR);
	if (rc)
		pr_err("BT_PWR gpio direction configuration failed:%d\n", rc);

	/* Pass the wl12xx platform data information to the wl12xx driver */
	wl12xx_wlan_data.irq = gpio_to_irq(WL12XX_WLAN_WOW);
	if (wl12xx_set_platform_data(&wl12xx_wlan_data)) {
		pr_err("Error setting wl12xx data\n");
		return -1;
	}

	wl1271_wifi_resource[0].start = wl1271_wifi_resource[0].end =
		gpio_to_irq(WL12XX_WLAN_WOW);
	platform_device_register(&wl1271_wifi_device);

	pr_info("==== gpio_to_irq(WL12XX_WLAN_WOW)=%d\n", wl12xx_wlan_data.irq);

	return 0;
}

This is how the 21.5 kernel handles the marvel sdio interface. The result is again that the kernel kicks the driver load automatically but again I get the same kernel crush. Therefore, this would mean 2 possible problems. First, I don’t do it the proper way, or second it’s a drivers bug. Probably it’s the first one.

This is the error log I get.

Hi dimtass,

  1. I’ve also made the sdmmc2 to work.
    Did SDIO enumerate successfully? Are the power rails to Wifi chip enabled properly? Would it be possible to share the working SDMMC2 log?

  2. I’ve tried to re-name the ‘platform_device tegra_sdhci_device1’ from ‘sdhci-tegra’ to ‘wl12xx’.
    I think the device name sdhci-tegra is the right value.

Hi b2.

This is a part of the log where the sdmmc2 is initialized.

I’ve also seen the CLK and the CMD on the oscilloscope and I’ve seen the pulses in both pins while booting. Therefore, I think that it probably works.

The problem is that now I’m getting a lot of Oops that are related to the driver and it seems like there are structures that their values are NULL. For example the struct wl1271_if_operations, that is used a lot from the driver seems that it’s not initialized

struct wl1271_if_operations {
	int __must_check (*read)(struct device *child, int addr, void *buf,
				 size_t len, bool fixed);
	int __must_check (*write)(struct device *child, int addr, void *buf,
				  size_t len, bool fixed);
	void (*reset)(struct device *child);
	void (*init)(struct device *child);
	int (*power)(struct device *child, bool enable);
	void (*set_block_size) (struct device *child, unsigned int blksz);
};

So, when the kernel tries to run power or set_block_size then I get an Oops.

Finally, what it worked (probably) for me is the following key points

So now, when I run

$ modprobe wl12xx

I get Oops that are related with the driver. I don’t have the logs right now, but I’ll post them.

I’ve found something strange and I don’t know if it affects the sdmmc2, but it seems that in drivers/mmc/host/sdhci-tegra.c there aren’t any t12x_tuning_coeffs and t12x_tap_hole_coeffs for sdhci-tegra.1.

I don’t know if this is important for the tegra driver to properly initialize the sdmmc2 interface but it’s missing. Maybe this is why, although the interface seems to be active, it can’t recognize the sdio interface of wl1271.
