How to turn off DRM

[hankwang]

Hi, 

    We have a i.MX8MQ and TI sn65dsi84. we want to turn off the backlight when brightness = 0. At the same time, turn off TI sn65dsi84. Where can we turn off TI sn65dsi84 (/sys/class) ?

Yes, we know that the status of sn65dsi84 can be disable in the DTS. we would like know if the status of sn65dsi84 can be disable in the user level (filesystem)?

do you mean that you need disable this after the board boot up?

[joanxie]

you can change the status of sn65dsi84 in the dts to disabled
