The PWM-DAC module does not require a hardware codec, but a dummy codec is needed for the driver. The dummy spdif codec driver, which is already upstream, is compatible with the one which JH7110 PWM-DAC needed. So we use it as the dummy codec driver for the JH7110 PWM-DAC module. The third patch depends on tag next-20230728 in linux-next branch. Changes since v1: - Rebase on tag v6.5-rc3. - Drop patch 1 and 2. - Drop the unneeded space and line in patch 3. - Use the dummy spdif codec driver instead of adding a new one. - Change "dai_link->stop_dma_first = 1" to "dai_link->trigger_stop = SND_SOC_TRIGGER_ORDER_LDC" in patch 4. - Drop the unneeded "status = "okay;" in patch 5. - Change some node names in patch 5. --- v1: https://lore.kernel.org/all/20230626110909.38718-1-hal.feng@starfivetech.com/ Hal Feng (3): ASoC: dt-bindings: Add StarFive JH7110 PWM-DAC controller ASoC: starfive: Add JH7110 PWM-DAC driver riscv: dts: starfive: Add JH7110 PWM-DAC support .../sound/starfive,jh7110-pwmdac.yaml | 76 ++ MAINTAINERS | 7 + .../jh7110-starfive-visionfive-2.dtsi | 99 +++ arch/riscv/boot/dts/starfive/jh7110.dtsi | 156 ++++ sound/soc/starfive/Kconfig | 9 + sound/soc/starfive/Makefile | 1 + sound/soc/starfive/jh7110_pwmdac.c | 787 ++++++++++++++++++ 7 files changed, 1135 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/starfive,jh7110-pwmdac.yaml create mode 100644 sound/soc/starfive/jh7110_pwmdac.c base-commit: 6eaae198076080886b9e7d57f4ae06fa782f90ef
