Subject: [PATCH v6 0/4] drm/rockchip: dw_hdmi: Add 4k@30 support
Date: Thu, 16 Feb 2023 11:24:43 +0100	[thread overview]
Message-ID: <20230216102447.582905-1-s.hauer@pengutronix.de> (raw)

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@30 resolution
  drm/rockchip: dw_hdmi: discard modes with unachievable pixelclocks
