drm/bridge: split HDMI Audio from DRM_BRIDGE_OP_HDMI
...
As pointed out by Laurent, OP bits are supposed to describe operations.
Split DRM_BRIDGE_OP_HDMI_AUDIO from DRM_BRIDGE_OP_HDMI instead of
overloading DRM_BRIDGE_OP_HDMI.

drm/bridge: synopsys: Add audio support for dw-hdmi-qp
...
Register the dw-hdmi-qp bridge driver as an HDMI audio codec.
The register values computation functions (for n) are based on the
downstream driver, as well as the register writing functions.
The driver uses the generic HDMI Codec framework in order to implement
the HDMI audio support.

drm/bridge: Pass full state to atomic_disable
...
It's pretty inconvenient to access the full atomic state from
drm_bridges, so let's change the atomic_disable hook prototype to pass
it directly.

drm/bridge: dw-hdmi-qp: drop atomic_check() callback
...
As drm_bridge_connector now provides atomic_check() implementation which
calls drm_atomic_helper_connector_hdmi_check(), drop the duplicating
callback from the bridge driver.

Replace .mode_valid() callback with .hdmi_tmds_char_rate_valid(). It is
more generic and is used in other mode validation paths. The rate
validation for .mode_valid() will be performed by the
drm_bridge_connector code.

supports the following features, among others:
* Fixed Rate Link (FRL)
* Display Stream Compression (DSC)
* 4K@120Hz and 8K@60Hz video modes
* Variable Refresh Rate (VRR) including Quick Media Switching (QMS), aka
Cinema VRR
* Fast Vactive (FVA), aka Quick Frame Transport (QFT)
* SCDC I2C DDC access
* TMDS Scrambler enabling 2160p@60Hz with RGB/YCbCr4:4:4
* YCbCr4:2:0 enabling 2160p@60Hz at lower HDMI link speeds
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)
Add library containing common helpers to enable basic support, i.e. RGB
output up to 4K@30Hz, without audio, CEC or any HDMI 2.1 specific
features.
