Hi Simon These patches enable HDMI sound on R-Car Salvator boards on H3/M3. Basically, HDMI sound support on "driver side" was already supported, but I didn't posted "DT side" patches, because it needed to confirm business relationship. Now it be cleared. But, unfortunately, DT "full_name" behavior was exchanged from v4.15. And driver assumeed that DT is using numerical suffixes, but this idea was rejected. Because of these reasons, it needs below patch. Simon, can you consider these patches on below ? git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git :: for-4.18 9ff7386656f5b7d9524ab7bdf69d508d14800d42 ("ASoC: rsnd: don't assume node full path name for HDMI probing") 1) : only for renesas, not for upstream 2) : for defconfig 3) - 10) : based on 9ff7386656f5b7d9524ab7bdf69d508d14800d42 Kuninori Morimoto (10): 1) arm64: renesas_defconfig: Enable CONFIG_SND_AUDIO_GRAPH_CARD 2) arm64: defconfig: Enable CONFIG_SND_AUDIO_GRAPH_CARD 3) arm64: dts: renesas: r8a7795: add HDMI sound support 4) arm64: dts: renesas: r8a7796: add HDMI sound support 5) arm64: dts: renesas: salvator-common: use audio-graph-card for Sound 6) arm64: dts: renesas: r8a7795-es1-salvator-x: enable HDMI sound 7) arm64: dts: renesas: r8a7795-salvator-xs: enable HDMI sound 8) arm64: dts: renesas: r8a7796-salvator-xs: enable HDMI sound 9) arm64: dts: renesas: r8a7795-salvator-x: enable HDMI sound 10) arm64: dts: renesas: r8a7796-salvator-x: enable HDMI sound .../boot/dts/renesas/r8a7795-es1-salvator-x.dts | 46 ++++++++++++++++++++++ arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 46 ++++++++++++++++++++++ .../arm64/boot/dts/renesas/r8a7795-salvator-xs.dts | 46 ++++++++++++++++++++++ arch/arm64/boot/dts/renesas/r8a7795.dtsi | 8 ++++ arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts | 28 +++++++++++++ .../arm64/boot/dts/renesas/r8a7796-salvator-xs.dts | 28 +++++++++++++ arch/arm64/boot/dts/renesas/r8a7796.dtsi | 4 ++ arch/arm64/boot/dts/renesas/salvator-common.dtsi | 38 ++++++++++-------- arch/arm64/configs/defconfig | 1 + arch/arm64/configs/renesas_defconfig | 1 + 10 files changed, 230 insertions(+), 16 deletions(-) -- 1.9.1
