To support HDMI audio on the rk3588 based devices, the generic HDMI
Codec framework is used in the dw-hdmi-qp DRM bridge driver.
The implementation is mainly based on the downstream driver, ported to the
generic HDMI Codec framework [1] recently merged in the DRM tree.
The parameters computation has been kept as is and the data stored in the
dw_hdmi_qp struct as been cleaned up.
The downstream kernel also implements a machine driver for HDMI audio but
it is doing exactly what the simple-audio-card driver does, so use that
instead in the ROCK 5B device tree.
Based on Linus' master branch.
Changes since v1:
- Remove useless audio_mutex (was used downstream for multiple drivers access
to audio functions)
- Let hdmi_codec build and setup audio infoframes
- Only access audio registers when connector is connected
- Rebased on master branch
