[Intel-gfx] [PATCH 1/3] drm/fourcc: Add 64 bpp half float formats

2018-11-28 Thread Kevin Strasser
Add 64 bpp 16:16:16:16 half float pixel formats. Each 16 bit component is formatted in IEEE-754 half-precision float (binary16) 1:5:10 MSb-sign:exponent:fraction form. An 'is_fp' attribute is added to drm_format_info so that drivers can easily distinguish these formats from those that might contai
