Re: [RFC/PATCH] drm: Add XRGB8626262 (RGB 6:6:6) pixel format

This format is an odd beast, implemented by Renesas R-Car hardware. It stores RGB 6:6:6 pixels in 32 bits as

Hello,

I came across this weird format on a Renesas SoC display controller. This is essentially XRGB8888 with the two low order bits of each component ignored by the hardware.

It sounds like it's no different than shoveling XRGB8888 down a 6bpc pipe w/o dithering.

Could we just pretend it's XRGB8888, or can the low order bits have some special meaning which would require treating them as special?
