Hello,
i want to add sensor cm32181 to IIO , i already use make menuconfig to build in Device Drivers->Industrial I/O support->Light sensors->CM32181 driver. And i edit tegra186-soc-i2c.dsti as fellow:
gen7_i2c: i2c@31c0000 {
#address-cells = <1>;
#size-cells = <0>;
#stream-id-cells = <1>;
compatible = “nvidia,tegra186-i2c”;
reg = <0x0 0x31c0000 0x0 0x100>;
interrupts = <0 TEGRA186_IRQ_I2C7 0x04>;
scl-gpio = <&tegra_main_gpio TEGRA_MAIN_GPIO(L, 0) 0>;
sda-gpio = <&tegra_main_gpio TEGRA_MAIN_GPIO(L, 1) 0>;
status = “disabled”;
clock-frequency = <400000>;
clocks = <&tegra_car TEGRA186_CLK_I2C7
&tegra_car TEGRA186_CLK_PLLP_OUT0
&tegra_car TEGRA186_CLK_I2C_SLOW>;
clock-names = “div-clk”, “parent”, “slow-clk”;
resets = <&tegra_car TEGRA186_RESET_I2C7>;
reset-names = “i2c”;
dmas = <&gpcdma 27>, <&gpcdma 27>;
dma-names = “rx”, “tx”;
cm32181@10 {
compatible = “capella,cm32181”;
reg = <0x10>;
interrupt-parent = <&gpio1>;
interrupts = <17 0>;
capella,hw_id = <0x81>;
capella,reg_cmd = <0x04>;
capella,reg_als_wh = <0xFFFF>;
capella,reg_als_wl = <0x0000>;
capella,calibscale = <10000>;
capella,mlux_per_bit = <5>;
capella,thd_percent = <5>;
};
};
but i see iio:device0~3 name not find cm32181. It’s not work.
which dsti should i edit?
And when it success , which /sys/bus/iio/devices/iio:device? will it show?
