[RESEND PATCH v5 0/3] drm: describe display bus format

[Boris Brezillon]

Hello,

Resending this series I depends on for the Atmel HLCDC driver which, BTW,
I really expect to be merged in 3.20.
Thierry, do you see any remaining issues that should be fixed ?
If not, Dave, Thierry, could you take it for 3.20 (or, if you prefer, I
could make it part of my PR for the atmel-hlcdc driver inclusion).

Here follows the usual description:

This series makes use of the MEDIA_BUS_FMT definition to describe how
the data are transmitted to the display.

This will allow drivers to configure their output display bus according
to the display capabilities.
For example some display controllers support DPI (or raw RGB) connectors
and need to specify which format will be transmitted on the DPI bus
(RGB444, RGB565, RGB888, ...).

This series also adds a field to the panel_desc struct so that one
can specify which format is natevely supported by a panel.

Regards,

Boris
