adds an encoder on component bind, so that it works with the Armada DRM
driver.
Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60,
with VGA as well as DVI.

This makes it possible to choose a different pixel format for the
endpoint. Modelled after what other LCD controllers use, including
marvell,pxa2xx-lcdc and atmel,hlcdc-display-controller and perhaps more.

Hi,
chained to this message are patches that are necessary to make the
Armada DRM driver useful on MMP2 and MMP3. They apply on top of
drm-armada-devel.
The first two patches were previously sent separately, around a year ago
or so. The v2 of the third one previosly only implemented only MMP2

There's a generic compatible string and the driver will work on a MMP2 as
well, using the same binding.

The port is a child, not a property. And should be accompanied by an

Hi,
chained to this message is another spin of a driver for CH7033.
Compared to the previous submission, the integration with device
component framework and creation of an encoder on component bind has
been removed. This means that until the Armada driver won't work with
this driver until it's a
