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) [1]: https://lore.kernel.org/all/20241224-drm-bridge-hdmi-connector-v10-0-dc89577cd438@linaro.org/ Detlev Casanova (1): arm64: dts: rockchip: Add HDMI0 audio output on rock-5b Sugar Zhang (1): drm/bridge: synopsys: Add audio support for dw-hdmi-qp arch/arm64/boot/dts/rockchip/rk3588-base.dtsi | 1 + .../boot/dts/rockchip/rk3588-rock-5b.dts | 19 + drivers/gpu/drm/bridge/synopsys/dw-hdmi-qp.c | 472 ++++++++++++++++++ 3 files changed, 492 insertions(+)
