In order to support the HDMI2.0 YUV420 display modes, this patch adds support for the YUV420 TMDS Clock divided by 2 and the controller passthrough mode. YUV420 Synopsys PHY support will need some specific configuration table to support theses modes. This patch is based on work from Zheng Yang <zhengyang@rock-chips.com> in the Rockchip Linux 4.4 BSP at [1] [1] https://github.com/rockchip-linux/kernel/tree/release-4.4 Cc: Zheng Yang <zhengyang@rock-chips.com> Signed-off-by:

Add support for SCDC Setup for TMDS Clock > 3.4GHz and enable TMDS Scrambling when supported or mandatory. This patch also adds an helper to setup the control bit to support the high TMDS Bit Period/TMDS Clock-Period Ratio as required with TMDS Clock > 3.4GHz for HDMI2.0 3840x2160@60/50 modes.

This is only used by drm_irq_install(), which is an optional helper. For legacy pci devices this is required (due to interrupt sharing without msi/msi-x), and just making this the default exactly matches the behaviour of all existing drivers using the drm_irq_install() helpers. In case that ever becomes wrong drivers can roll their own irq handling, as many drivers already do (for other reasons like needing a threaded interrupt handler, or having an entire pile of different interrupt sources). v2: Rebase v3: Improve commit message (Emil) Cc: Sam Ravnborg <sam@ravnborg.org> Reviewed-by:

If a non-legacy driver calls these it's valid to assume there is interrupt support.
