Hi Nikola,

This patch uses the (almost) the same settings as those found in the original Android firmware. As such, it gurantees good compatibility.

V2: Small fixes/changes to the config

V3: Checkpatch fixes

Please try to fix those before hitting Send ;-) and please note patch versions within the brackets ([PATCH v3]).

So the .dts file would need to go through a Linux review first. Please send it there, and we will pick it up once it has been merged.

Cheers, Andre
