[PATCH 00/16] Add Allwinner H3/H5/H6/A64 HDMI audio
Hi, This a merge of serie: - Add Add H6 I2S support https://patchwork.kernel.org/cover/11497007/ - Add Allwinner H3/H5/A64 HDMI audio https://patchwork.kernel.org/cover/11510511/ I merge both serie because there is a similar issue regarding the I2S polarity. This need to be investigated under a scope and see if the comment is still true for Allwinner H6 and previous SoC. LibreElec team found that we have to introduce the "simple-audio-card,frame-inversion" property with recent mainline change. In order to make HDMI audio work. Maybe the I2S polarity is good or maybe the silicium has an issue but not present for HDMI I2S or not present in TDM mode... I cannot do it myself, so if someone want to to do it please feel free. Regarding the discussion we had here: https://patchwork.kernel.org/patch/11510521/ I didn't switch to generic hdmi card-name and used name like: sun8i-h3-hdmi, sun50i-h6-hdmi, etc.... Despite this wrong comment the rest of the serie introduce some fix that should be merged even if it's without the H6 support. Regards Clement Change since v1: - drop allwinner,playback-channels property - use coherent hdmi,card-name - indentation fix - collect tags Clément Péron (2): ASoC: sun4i-i2s: Fix sun8i volatile regs arm64: dts: allwinner: h6: Enable HDMI sound for Beelink GS1 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 (11): ASoC: sun4i-i2s: Adjust LRCLK width ASoC: sun4i-i2s: Set sign extend sample ASoc: sun4i-i2s: Add 20 and 24 bit support ASoC: sun4i-i2s: Adjust regmap settings 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 .../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/sunxi-h3-h5.dtsi | 33 ++ .../boot/dts/allwinner/sun50i-a64-pine64.dts | 8 + arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 35 +++ .../dts/allwinner/sun50i-h6-beelink-gs1.dts | 8 + arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 33 ++ sound/soc/sunxi/sun4i-i2s.c | 281 +++++++++++++++++- 9 files changed, 410 insertions(+), 6 deletions(-) -- 2.25.1

We should have sun50i_h6 as prefix. The A64 is also part of the sun50i family and supported through the sun8i callbacks, so it's pretty confusing if you don't have the soc name in there. Maxime

No, sorry, I had missed the subtraction happening in the macro. So there's no problem here. Thanks, Samuel

That's a comment that needs to be checked using a Logic analyzer (that I don't have). It's a copy paste from the previous generation. But this seems wrong as we need to specify "simple-audio-card,frame-inversion;" in the device-tree. Regards, Clement

This is just a note; I'm not suggesting a change here: This does nothing, because SUN4I_I2S_FMT1_REG only affects PCM mode, which is not implemented in the driver for the sun4i generation of hardware. PCM mode requires setting bit 4 of SUN4I_I2S_CTRL_REG, and then configuring SUN4I_I2S_FMT1_REG instead of SUN4I_I2S_FMT0_REG. Regards, Samuel

This is just a note; I'm not suggesting a change here:
This does nothing, because SUN4I_I2S_FMT1_REG only affects PCM mode, which is not implemented in the driver for the sun4i generation of hardware. PCM mode requires setting bit 4 of SUN4I_I2S_CTRL_REG, and then configuring SUN4I_I2S_FMT1_REG instead of SUN4I_I2S_FMT0_REG.
Thanks for the catch, So i will drop it for sun4i. Regards, Clement

I'm not sure what has WSS with physical width and DMA?
This is the change where creating a S24_LE stream no longer fails with -EINVAL. So this is the change where userspace stops downsampling 24-bit audio sources. So this is the change where playback of 24-bit audio sources breaks, because WSS is programmed wrong.
As a side note, I wonder why we use the physical width (the spacing between samples in RAM) to drive the slot width. S24_LE takes up 4 bytes per sample in RAM, which we need for DMA. But I don't see why we would want to transmit the padding over the wire. I would expect it to be transmitted the same as S24_3LE (which has no padding).

Allwinner DMA engines support only 1, 2, 4 and sometimes 8 bytes for bus width, so if sample is 24 bits in size, we have no other way but to transmit padding too.
I understand why we do 4 byte DMA from RAM <=> I2S FIFO; that was not my question. I'm referring to the actual wire format (FIFO <=> PCM_DIN/DOUT). The sample is already truncated from 32 bits to 24 bits in the FIFO -- that's what TXIM and RXOM in FIFO_CTRL control. If a sample is 24 bits wide, why would we send 32 BCLKs for every LRCK? I would expect the slot width to match the sample resolution by default. But yet we have this code in the driver: unsigned int word_size = params_width(params); unsigned int slot_width = params_physical_width(params); I think slot_width should be the same as word_size, and I suggest changing it before adding 20/24-bit support.

Generally speaking, the slot width doesn't necessarily match the physical width. With TDM for example you may very well have slots larger than their samples. That being said, S24 is explicitly a format where you send a sample of 24 bits in a 32-bit word (in the lowest three bytes, little endian) See: https://elixir.bootlin.com/linux/v5.9-rc3/source/sound/core/pcm_misc.c#L75 https://mailman.alsa-project.org/pipermail/alsa-devel/2013-April/061073.html 24 bits of data over three bytes like you suggest is S24_3LE Maxime

24 bits of data over three bytes like you suggest is S24_3LE
My understanding is physical_width refers to the in memory representation, but shouldn't be used to control the slot width on the bus. If not specified otherwise (say through the set_tdm callback), and if the appropriate BCLK is supported, then the slot should be just large enough to hold the data. Thanks, Charles

Indeed. The framework isn't great here in tying the memory and wire formats together, ideally there would be more support for them being unrelated without DPCM.

dai-tdm-slot-width is needed to override automatic slot width selection. It should always be 32 for HDMI, no matter what is actual physical sample width. In this case this property is abused to set width also for I2S mode of operation. IMO there is no sense to duplicate code because I2S variant would work exactly the same, except name would be different. I'm not sure about dai-tdm-slot-num. Marcus, can you explain the need for this property? Would it be better to implement separate link driver instead of using simple- card to hide all this properties into the code? Best regards, Jernej
