[PATCH v6 0/4] drm/rockchip: dw_hdmi: Add 4k at 30 support

[Sascha Hauer]

One small fix compared to the last version, when checking for valid
resolutions I accidently compared the current mode width with the
maximum allowed height which resulted in wrong resolutions being
discarded.

Changes since v5:
- Fix wrong check width vs. height

Changes since v4:
- Use struct vop_reg to store resolutions
- Only check for valid clock rates when clock != NULL

Changes since v3:
- Add patch to limit VOP resolutions to hardware capabilities

Changes since v2:
- Use correct register values for mpll_cfg
- Add patch to discard modes we cannot achieve

Changes since v1:
- Allow non standard clock rates only on Synopsys phy as suggested by
  Robin Murphy

Sascha Hauer (4):
  drm/rockchip: vop: limit maximium resolution to hardware capabilities
  drm/rockchip: dw_hdmi: relax mode_valid hook
  drm/rockchip: dw_hdmi: Add support for 4k at 30 resolution
  drm/rockchip: dw_hdmi: discard modes with unachievable pixelclocks
