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 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 | 424 ++++++++++++++++++ 3 files changed, 444 insertions(+)
