Hello All,
This series implements support for the Versatile Express
video output pipeline, which is not the simplest one available...
It is meant as a RFC only and I'm hoping to attract all possible
feedback (*including* naming ;-).
The VE's "MultiMedia Bus" [1] comprises three video signal sources
(motherboard's CLCD cell and a implementation-specific driver
on each of the daugtherboards) and a FPGA multiplexer routing
data from one of the sources to DVI/HDMI formatter chip (Sii9022).

The series is based on Laurent Pinchart's Common Display Framework
patch (not in mainline yet, v2 discussed here: [2]) and extends it
by adding DT bindings and basic support for TFT panels.
The CLCD driver has been adapted to work with the framework and
the Device Tree information.
Also a set of drivers for the VE-specific components is included
(note that the sii9022 is now driven via the moterboard firmware;
this is intended to be replaced by a proper I2C driver for the
chip).
It is worth mentioning that the CDF caters for both fbdev and DRM
so the solution should be suitable for all potential DRM-driven
display controllers.
