[Letux-kernel] Debugging 4.11-rc6 on GTA04

Hi,
I have found a little time to upgrade our tree to 4.11-rc6
and for the first time there were no kernel oops on the GTA04(A5)
until login.

Only the LCD is broken :(

On the Pyra the same kernel works well. So it seems to be
OMAP3 specific (maybe again some interference of the TILER
addition, but I can easily check by merging my 4.11-rc6
without TILER).

Unfortunately the crtc_error makes the device almost unuseable after
the login:

The current code is here:

BR,
Nikolaus
