[Intel-gfx] [PATCH v2 2/2] drm/i915/icl: Implement half float formats
Kevin Strasser

Fri Jan 18 17:59:24 UTC 2019
64 bpp half float formats are supported on hdr planes only and are subject
to the following restrictions:
* 90/270 rotation not supported
* Yf Tiling not supported
* Frame Buffer Compression not supported
* Color Keying not supported
v2:
- Drop handling pixel normalize register
- Don't use icl_is_hdr_plane too early
