Hi,
This serie aims at:
- Updating HW up-sampling method according to the format type.
- Adding color-encoding properties if layer can support YUV format,
and updating HW YUV-RGB matrix state according to the color-encoding
properties.
This patch series depends on:
- https://patchwork.freedesktop.org/series/58710/
- https://patchwork.freedesktop.org/series/59000/
- https://patchwork.freedesktop.org/series/59002/
