I started with next-20131219, merged your latest drm/for-next branch,
and this doesn't seem to work.
With Laxman's regulator patch applied and your 1/10 dropped since it's a
duplicate, the LCD backlight doesn't light up. I extracted the following
from this patch to fix Laxman's regulator definitions:
gpio = <&gpio TEGRA_GPIO(P, 2) GPIO_ACTIVE_LOW>;
+ enable-active-high;
};
and the backlight does light up, but that's all.
With Laxman's regulator patch reverted and your patch 1/10 applied to
replace it, I see the backlight working without having to manually fix
up the device tree. However, that's still all; nothing is actually
displayed.
Again, can you please rebase this whole series on the latest Tegra
for-3.14/dt and sort out the issues? Thanks.
