Hi:
we have a customized board,the EDP interface is ok,but when I “dmesg”,I found:

[   21.408728] vdd_ds_1v8 regulator get failed
[   21.408730] edp regulator get failed

WayneWWW says "just comment out those regulator checks in edp panel driver if you don't need it",but I could not found the "board-panel.c",<b>so where is the default edp panel driver in tx2 </b>?

XuXiang,

panel-a-edp-1080p-14-0.c is what you are looking for.

board-panel.c is for tx1 only. On tx2, those panel selection codes are under nvdisp_stub.c

but,where is “nvdisp_stub.c” ?

find -name “nvdisp_stub.c” ,get nothing.

It should be under kernel/t18x/driver/videos/tegra/dc/nvdisp

It’s under kernel/… ,not kernel/kernel-4.4 !
Thank you very much!!!
