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)?
