[PATCH v1 0/2] Add HDMI audio on the Radxa ROCK 5B

[Detlev Casanova]

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 commit f1359f46f1f1 (tag: drm-misc-next-fixes-2025-01-16)
