[RFC PATCH v2 0/6] A drm_plane API to support HDR planes

[Harry Wentland]

We are looking to enable HDR support for a couple of single-plane and
multi-plane scenarios. To do this effectively we recommend new interfaces
to drm_plane. The first patch gives a bit of background on HDR and why we
propose these interfaces.

v2:
 * Moved RFC from cover letter to kernel doc (Daniel Vetter)
 * Created new color space property instead of abusing
   color_encoding property (Ville)
 * Elaborated on need for named transfer functions
 * Expanded on reason for SDR luminance definition
 * Dropped 'color' from transfer function naming
 * Added output_transfer_function on crtc

Bhawanpreet Lakha (3):
  drm/color: Add transfer functions for HDR/SDR on drm_plane
  drm/color: Add sdr boost property
  drm/color: Add color space plane property

Harry Wentland (3):
  drm/doc: Color Management and HDR10 RFC
  drm/color: Add output transfer function to crtc
  drm/amd/display: reformat YCbCr-RGB conversion matrix
