MIPI 10.1 inch lcd setting up
#1
Hi!

I am trying to connect B101UAN01.7 display(1920 x 1200) without any success.

Is pine64's driver supports other display than native 7"? If so, then could you please help me to understand where can be error?

Here is cutout from my device tree for 10.1" display

                 lcd0@01c0c000 {
                        compatible = "allwinner,sunxi-lcd0";

I am interested in this as well. Any update on connecting a 1920x1200 MIPI LCD to the Pine64-LTS?
