Subject[PATCH 2/2 v3 resend] dt-bindings: display: imx: entry for AUS mode
Allow setting the AUS mode for a display from the device tree.
Use an optional boolean property. AUS mode can be set only on imx21
and compatible chipsets.

re-sending v3, rebased against current linux-next
it seems this got lost along the way, there was a bit of confusion
whether to split this in two patches or not

use a boolean DT property instead of the register value
separate patches for DT binding and code changes

re-sending DT bindings and code changes as one patch
