This patch fixes a regression that Display panel doesn't work
since HW trigger mode was supported.
The trigger mode should be changed on PSR(Panel Self Refresh)
mode of Panel device according to HW guy's saying. However,
with previous HW trigger support, trigger mode could been changed
in normal mode of Panel device.
So this patch makes sure to change the trigger mode after power off
and on again. Later we need to add PSR relevant codes instead.
I'm afraid this patch doesn't fix the regression I'm seeing on my
Exynos5250 Chromebook.
I found out that using the 4.6 device tree allows the display to
function correctly (at least for a while), just enough to see it dying
before reaching userspace (and it scrolls up way to quickly for me to
read it). Adding printk_delay results in a hanging system.
Can someone with a servo-board investigate this? I'll try to bisect it
further, but an actual backtrace would help.
Thanks,
M.
