Tool/software: Linux
my board is imx8qxp,data pata:mipi dsi --> ssd2858-->941-->948-->lcd(1920x720);
in boot up, the gpio3 on 948 sometimes is pull down to 0V while the input GPIO3 to 941 is always 3.3V;
but after there are contents on screen (means display is on,) the gpio3 on 948 is normal to 3.3V;
so,when no dislapy contents input to 941,the 941-948 can transport by GPIO3 independently? 
?
