[PATCH 0/4] Enable Y210, Y212, Y216 formats for ICL

[Swati Sharma]

These patches enable packed format YUV422-Y210, Y212 and Y216
for 10, 12 and 16 bit respectively for ICL.

For user space component IGT:WIP

Vidya Srinivas (4):
  drm: Add Y210, Y212, Y216 format definitions and fourcc
  drm/i915: Add Y210, Y212, Y216 plane control definitions

[PATCH 1/4] drm: Add Y210, Y212, Y216 format definitions and fourcc

[Swati Sharma]

From: Vidya Srinivas <vidya.srinivas@intel.com>

The following pixel formats are packed format that follows 4:2:2
chroma sampling. For memory represenation each component is
allocated 16 bits each. Thus each pixel occupies a DWORD.

Y210: 	Valid data occupies MSB 10 bits.
	LSB 6 bits are filled with zeroes.
Y212: 	Valid data occupies MSB 12 bits.
	LSB 4 bits are filled with zeroes.
Y216: 	Valid data occupies 16 bits,
	doesn't require any padding bits.

First 16 bits stores the Y value and the next 16 bits stores one
of the chroma samples alternatively. The first luma sample will
be accompanied by first U sample and second luma sample is
accompanied by the first V sample.

you should also set is_yuv to true.

Apart from this there can be different order for YUV samples, Are you 
going to add those as well?

While programming YUV pixel format, you also need to program order of 
samples in bits [17:16]
BTW 64 bits pixel format are not supported in all the planes, these are 
supported only in HDR planes.
You should handle that as well.

I don't think this comments reflect very well the actual layout of the
color planes, I think you need to describe the padding as well.

Just looking at the comments without reading the commit message you
could easily assume that the padding happens is in the [63:40] bits.
