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

H6 I2S is very similar to that in H3, except it supports up to 16
channels.

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.

According to the manual, LEFT_J and RIGHT_J should use the same calculation as
I2S, not the one for PCM/DSP.

From the description in the manual, this looks off by one. The number of BCLKs
per LRCK is LRCK_PERIOD + 1.

This comment makes us sound a lot more confident than I think we actually are.

According to the manual, LEFT_J and RIGHT_J should use the same calculation as
I2S, not the one for PCM/DSP.

From the description in the manual, this looks off by one. The number of BCLKs
per LRCK is LRCK_PERIOD + 1.

This comment makes us sound a lot more confident than I think we actually are.

Are you sure? Macro SUN8I_I2S_FMT0_LRCK_PERIOD() is defined as follows:
#define SUN8I_I2S_FMT0_LRCK_PERIOD(period) ((period - 1) << 8)
which already lowers value by 1.

Are you sure? Macro SUN8I_I2S_FMT0_LRCK_PERIOD() is defined as follows:
#define SUN8I_I2S_FMT0_LRCK_PERIOD(period) ((period - 1) << 8)
which already lowers value by 1.

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

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.

Some codecs such as i2s based HDMI audio and the Pine64 DAC require
a different amount of bit clocks per frame than what is calculated
by the sample width. Use the values obtained by the tdm slot bindings
to adjust the LRCLK width accordingly.

It looks like the existing code would have the same problem, that this should be

H6 I2S is very similar to H3, except that it supports up to 16 channels
and thus few registers have fields on different position.

On the newer SoCs such as the H3 and A64 this is set by default
to transfer a 0 after each sample in each slot. However the A10
and A20 SoCs that this driver was developed on had a default
setting where it padded the audio gain with zeros.
This isn't a problem while we have only support for 16bit audio
but with larger sample resolution rates in the pipeline then SEXT
bits should be cleared so that they also pad at the LSB. Without
this the audio gets distorted.
Set sign extend sample for all the sunxi generations even if they
are not affected. This will keep coherency and avoid relying on
default.

Isn't it coherence? But I guess consistency would be a better fit here.

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.

Samuel

Thanks for the catch,
So i will drop it for sun4i.

Thanks for the catch,
So i will drop it for sun4i.

This breaks the sun4i variants, because sun4i_i2s_get_wss returns 4 for a 32 bit
width, but it needs to return 3.
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). It did not matter before, because the only supported
format had no padding.
Regards,
Samuel

This breaks the sun4i variants, because sun4i_i2s_get_wss returns 4 for a 32 bit
width, but it needs to return 3.
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). It did not matter before, because the only supported
format had 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.

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.

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.

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.

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

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:

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.

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.

The FIFO TX reg is volatile and sun8i i2s register
mapping is different from sun4i.
Even if in this case it's doesn't create an issue,
Avoid setting some regs that are undefined in sun8i.

I'm not sure why you need to use the TDM stuff here. IIRC the HDMI
controller can output on up to 6 channels, so how would that work out?

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
