In which device tree file is the default dsi node

[waldemar.friesen]

hello people,

I could not find the file which works with that code:

/* DSI mapped to tegradc.1 */
		dc@54240000 {
			status = "okay";
			nvidia,dc-or-node = "/host1x/dsi";
			nvidia,dc-connector = <&dsi>;
			nvidia,fb-bpp = <24>; /* bits per pixel */
			/* DSI supplies */
			/*avdd_dsi_csi-supply = <&max77620_sd3>; I don't need this, but otherwise nothing works*/
			/*avdd_lcd-supply = <&battery_reg>;
			dvdd_lcd-supply = <&battery_reg>;
			vdd_lcd_bl_en-supply = <&battery_reg>;
			vdd_lcd_bl-supply = <&battery_reg>;*/
		};

please help me to find that file. I looked already for “dsi” string and found many of them but it can be same where else in kernel4.9 and not only where I have searched.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Hi,
it was very good, if the file organization were explained. Because I saw any files, which are not used. Eg. what is the difference between files:

1. tegra210-porg-gpio-p3448-0002-b00.dtsi
2. tegra210-porg-gpio-p3448-0002-a02.dtsi
3. tegra210-porg-gpio-p3448-0000-a02.dtsi

It means different kinds of modules.

As you know, there are sdcard module and emmc module.
p3448-0000 is for sdcard module
p3448-0002 is for emmc module.

And a02 is an old sku that released in 2019. Generally all the modules in market now is b00/b01 module.
