. Add display mode check operaion to mixer driver
- Mixer IP also can put certain restrictions on the proposed
display modes and these restrictions need to be considered
during mode negotiation, which happens immediately after
edid parsing.
. Set correct mode for range of resolutions
- With this patch, the mixer driver could find the correct mode
for the range of resolutions upto 1080 vertical lines.
. Support extra resolution for hdmi
- This patch programs the core and timing generator registers
using the timing data provided in drm_display_mode without
hard-coded configurations. So this patch adds additional PHY
configs to allow us to support more permissible resolutions
and refresh rates.
. Add device tree support for g2d
