[PATCH 0/4] drm/fsl-dcu: add TCON and Vybrid support

[Stefan Agner <stefan@agner.ch>]

This patchset adds the missing pieces to make the Freescale
DCU DRM driver work on Freescale Vybrid.

Foremost, it adds support for the timing controller (TCON)
module. The module is between the Display Controller and the
actual output pins. It allows to alter the timings for RAW
TFT displays, but can also operate in a bypass mode. This
change has only support for the bypass mode.

Earlier variants of the DCU DRM driver configured the TCON
module in bypass mode, however this has been removed and
postponed. The last variant with the TCON code was v9:

This change is an attempt to implement a proper driver.
Ideas have been taken from the sun4i Tcon driver:

The patchset depends on my fsl-dcu fixes patchset:
