[0/3] drm/ingenic: Add support for delta-RGB panels

Hi,

This patchset adds support for delta-RGB panels to the ingenic-drm
driver. Delta-RGB panels have diamond-pattern subpixel layout, and
expect odd lines to have RGB subpixel ordering, and even lines to have
GBR subpixel ordering.

Such panel is used in the YLM (aka. Anbernic) RG-99, RG-300, RG-280M
and RG-280V handheld gaming consoles.

Cheers,
-Paul

Strange panel, at least strange bit order.
Patches looks good and are all:
