Subject: [PATCH v3 0/2] drm/bridge: it6505: add audio support with DRM HDMI
 codec framework

For supporting audio form I2S to DP audio data sub stream.

Add hdmi_audio callbacks to drm_bridge_funcs for the HDMI codec 
framework.

The DRM_BRIDGE_OP_HDMI flag in bridge.ops must be set, 
and implement necessary callbacks for the drm_bridge_connector 
to enable the HDMI codec.
