[PATCH] ASoC: ti: davinci-evm: Remove redundant null check before clk_disable_unprepare
by Xu Wang 02 Nov '20

02 Nov '20

Because clk_disable_unprepare() already checked NULL clock parameter, so the additional check is unnecessary, just remove it.

[PATCH v10 00/15] Add Allwinner H3/H5/H6/A64 HDMI audio
by Clément Péron 02 Nov '20

02 Nov '20

Hi, This series add H6 I2S support and the I2S node missing to support HDMI audio in different Allwinner SoC. As we first use some TDM property to make the I2S working with the simple soundcard. We have now drop this simple sound card and a proper dedicated soundcard will be introduce later. This make the title of this series wrong now but to be able to follow the previous release I keep the same name. Regards, Clement Change since v9: - fix lrck_period computation for I2S justified mode Change since v8: - move the comment near the function prototype - collect Maxime Ripard tags Change since v7: - rebase on next-20201026 - comment about slots and slot_width Change since v6: - move set_channel_cfg() in first position - convert return value to decimal Change since v5: - Drop HDMI simple soundcard - Collect Chen-Yu Tsai tags - Configure channels from 9 to 15. - Remove DMA RX for H3/H5 - Fix Documentation for H3/H5 Change since v4: - add more comment on get_wss() and set_channel_cfg() patch - merge soundcard and DAI HDMI patches Change since v3: - add Samuel Holland patch to reconfigure FIFO_TX_REG when suspend is enabled - readd inversion to H6 LRCK sun50i_h6_i2s_set_soc_fmt() - Fix get_wss() for sun4i - Add a commit to fix checkpatch warning Change since v2: - rebase on next-20200918 - drop revert LRCK polarity patch - readd simple-audio-card,frame-inversion in dts - Add patch for changing set_chan_cfg params Change since v1: - rebase on next-20200828 - add revert LRCK polarity - remove all simple-audio-card,frame-inversion in dts - add Ondrej patches for Orange Pi board - Add arm64 defconfig patch Clément Péron (7): ASoC: sun4i-i2s: Fix lrck_period computation for I2S justified mode ASoC: sun4i-i2s: Change set_chan_cfg() params ASoC: sun4i-i2s: Change get_sr() and get_wss() to be more explicit ASoC: sun4i-i2s: Fix sun8i volatile regs ASoC: sun4i-i2s: fix coding-style for callback definition arm64: defconfig: Enable Allwinner i2s driver dt-bindings: sound: sun4i-i2s: Document H3 with missing RX channel possibility Jernej Skrabec (3): ASoC: sun4i-i2s: Add support for H6 I2S dt-bindings: ASoC: sun4i-i2s: Add H6 compatible arm64: dts: allwinner: h6: Add I2S1 node Marcus Cooper (4): ASoC: sun4i-i2s: Set sign extend sample ASoC: sun4i-i2s: Add 20 and 24 bit support arm64: dts: allwinner: a64: Add I2S2 node arm: dts: sunxi: h3/h5: Add I2S2 node Samuel Holland (1): ASoC: sun4i-i2s: Fix setting of FIFO modes .../sound/allwinner,sun4i-a10-i2s.yaml | 6 +- arch/arm/boot/dts/sunxi-h3-h5.dtsi | 13 + arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 14 + arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 13 + arch/arm64/configs/defconfig | 1 + sound/soc/sunxi/sun4i-i2s.c | 388 +++++++++++++++--- 6 files changed, 378 insertions(+), 57 deletions(-) -- 2.25.1

[PATCH v2 0/7] Add support for Rpi4b + Cirrus Lochnagar2 and CS47L15
by Richard Fitzgerald 02 Nov '20

02 Nov '20

This set of patches provides support for using the Raspberry Pi 4b with a Cirrus Logic Lochnagar 2 audio development platform plus Cirrus Logic CS47L15 codec. Patches are needed to audio-graph-card to enable support for setting the component sysclks and plls. The codec sysclks and plls cannot be placed under the clock framwork because they are I2C/SPI-connected peripherals and access to the registers would cause a nested get of the I2C/SPI bus clock. The clock framework does not support this and it would result in a deadlock.

[PATCH v4 00/22] Add Allwinner H3/H5/H6/A64 HDMI audio
by Clément Péron 02 Nov '20

02 Nov '20

Hi, New test done by Maxime using TDM show that's LRCK is indeed inverted so I drop the patch reverted in v2. And HDMI requires an inverted LRCK so let's readd the frame-inversion in the device-tree. I have also added a patch to change set_chan_cfg. Please note that I can't test TDM and only have a Allwinner H6. So test and comment on other Allwinner chips are welcome! Regards, Clement Change since v3: - add Samuel Holland patch to reconfigure FIFO_TX_REG when suspend is enabled - readd inversion to H6 LRCK sun50i_h6_i2s_set_soc_fmt() - Fix get_wss() for sun4i - Add a commit to fix checkpatch warning Change since v2: - rebase on next-20200918 - drop revert LRCK polarity patch - readd simple-audio-card,frame-inversion in dts - Add patch for changing set_chan_cfg params Change since v1: - rebase on next-20200828 - add revert LRCK polarity - remove all simple-audio-card,frame-inversion in dts - add Ondrej patches for Orange Pi board - Add arm64 defconfig patch Clément Péron (6): ASoC: sun4i-i2s: Change set_chan_cfg() params ASoC: sun4i-i2s: Change get_sr() and get_wss() to be more explicit ASoC: sun4i-i2s: Fix sun8i volatile regs arm64: dts: allwinner: h6: Enable HDMI sound for Beelink GS1 arm64: defconfig: Enable Allwinner i2s driver ASoC: sun4i-i2s: fix coding-style for callback definition Jernej Skrabec (3): ASoC: sun4i-i2s: Add support for H6 I2S dt-bindings: ASoC: sun4i-i2s: Add H6 compatible arm64: dts: allwinner: h6: Add HDMI audio node Marcus Cooper (9): ASoC: sun4i-i2s: Set sign extend sample ASoc: sun4i-i2s: Add 20 and 24 bit support arm: dts: sunxi: h3/h5: Add DAI node for HDMI arm: dts: sunxi: h3/h5: Add HDMI audio arm64: dts: allwinner: a64: Add DAI node for HDMI arm64: dts: allwinner: a64: Add HDMI audio arm: sun8i: h3: Add HDMI audio to Orange Pi 2 arm: sun8i: h3: Add HDMI audio to Beelink X2 arm64: dts: allwinner: a64: Add HDMI audio to Pine64 Ondrej Jirman (3): arm64: dts: allwinner: Enable HDMI audio on Orange Pi PC 2 ARM: dts: sun8i-h3: Enable HDMI audio on Orange Pi PC/One arm64: dts: sun50i-h6-orangepi-3: Enable HDMI audio Samuel Holland (1): ASoC: sun4i-i2s: Fix setting of FIFO modes .../sound/allwinner,sun4i-a10-i2s.yaml | 2 + arch/arm/boot/dts/sun8i-h3-beelink-x2.dts | 8 + arch/arm/boot/dts/sun8i-h3-orangepi-2.dts | 8 + arch/arm/boot/dts/sun8i-h3-orangepi-one.dts | 8 + arch/arm/boot/dts/sun8i-h3-orangepi-pc.dts | 8 + arch/arm/boot/dts/sunxi-h3-h5.dtsi | 33 ++ .../boot/dts/allwinner/sun50i-a64-pine64.dts | 8 + arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 34 ++ .../dts/allwinner/sun50i-h5-orangepi-pc2.dts | 8 + .../dts/allwinner/sun50i-h6-beelink-gs1.dts | 8 + .../dts/allwinner/sun50i-h6-orangepi-3.dts | 8 + arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 33 ++ arch/arm64/configs/defconfig | 1 + sound/soc/sunxi/sun4i-i2s.c | 374 +++++++++++++++--- 14 files changed, 487 insertions(+), 54 deletions(-) -- 2.25.1

Hello all, I own this card since recently: 03:00.0 Audio device: C-Media Electronics Inc CM8888 [Oxygen Express] Subsystem: C-Media Electronics Inc HDA Controller Flags: bus master, fast devsel, latency 0, IRQ 31, IOMMU group 7 Memory at fcd00000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel and I found out it doesn't work great. Only headphone output is functioning, RCA line out does not (haven't checked the rest). I found models list in /usr/lib/modules/5.9.2-arch1-1/build/Documentation/sound/hd-audio/models.rst and tested them all using a rmmod / modprobe bash script but none of them seems to enable RCA output. Windows drivers have possibility to switch between headphone and RCA output from manufacturer's app (there is a click sound coming from electronics of the card when I do this). I never tampered with low level hardware and I'm not familiar with ALSA development but what I was thinking is that maybe an ALSA snd_hda_intel developer would be interested in receiving this card for tests? -- Pozdrawiam / Greetings Marcin Kocur █
