Hi,

This is exactly the same as v4 but with more details in some commit log
and also device-tree soundcard and DAI node have been merged.

Regards,
Clement

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

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

As slots and slot_width can be overwritter in case set_tdm() is
called. Avoid to have this logic in set_chan_cfg().

Instead pass the required values as params to set_chan_cfg().

This will also avoid a bug when we will enable 20/24bits support,
i2s->slot_width is not actually used in the lrck_period computation.

We are actually using a complex formula to just return a bunch of
simple values. Also this formula is wrong for sun4i when calling
get_wss() the function return 4 instead of 3.

Replace this with a simpler switch case.

Also drop the i2s params which is unused and return a simple int as
returning an error code could be out of range for an s8 and there is
no optim to return a s8 here.

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

From: Marcus Cooper <codekipper@gmail.com>

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 consistency and avoid relying on
default.

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.

Because SUN4I_I2S_FIFO_CTRL_REG is volatile, writes done while the
regmap is cache-only are ignored. To work around this, move the
configuration to a callback that runs while the ASoC core has a
runtime PM reference to the device.

Add the I2S node used by the HDMI and a simple-soundcard to
link audio between HDMI and I2S.

Note that the HDMI codec requires an inverted frame clock and
a fixed I2S width. As there is no such option for I2S we use
TDM property of the simple-soundcard to do that.

Checkpatch script produces warning:
WARNING: function definition argument 'const struct sun4i_i2s *'
should also have an identifier name.

Let's fix this by adding identifier name to get_bclk_parent_rate()
and set_fmt() callback definition.

Nit, since it supports up to 16 channels, you might want to map all 16 of them
now, instead of having to come back and fix it later.

Code wise, this patch is

It doesn't seem that set_tdm_slot() would get called concurrently
with hw_params(), at least not for the simple-card family. If so
then we'd have more problems like mismatched slots/slot-width
due to no serialization when interacting with those values.

Based on the bug you highlighted in your expanded commit log, the simpler fix
would be to look at i2s->slot_width in addition to i2s->slots, and replace
params_physical_width(params) accordingly.

Also, I would put fixes (even preparatory ones) before patches that introduce
support for new features and hardware. That makes them easier to backport if
needed.

BTW, it is entirely possible that the compiler optimizes your switch-case

Doesn't this end up limiting the number of audio channels HDMI can carry?
AFAICT the TDM properties are all optional, so just leave it out.

Same goes for the other two patches.

Sorry, missed this one.

Given that usage for this interface is transmit only, and there is no
RX DRQ number assigned to it, you should drop the RX DMA number and name.

Thanks for the review. Do you mean there is missing MAP0 for RX/TX ?

Sorry maybe the commit log is not clear.
I was not talking about a concurrent effect but more if the slot_width is setted
then we don't properly use it later.

That's what I did in the first version but was pointed out by Samuel
that the same logic
was done several times. As I can avoid it by passing the correct
params it's simpler.

I will wait for Maxime to comment on this. Regarding the doc fixes tag
should only be used
to fix a previous commit. This will make the fixes commit a bit more
complicated for stable kernel team.

Thanks for your review :)

Indeed if there is no DRQ number assigned we shouldn't have it in the
device-tree

but Samuel told me that the `make dtbs_check` reports:

i2s@1c22800: dma-names:0: 'rx' was expected
i2s@1c22800: dma-names: ['tx'] is too short
i2s@1c22800: dmas: [[28, 27]] is too short

Should I fix the YAML so?

Clement

After reviewing the H6 User Manual it seems to be assigned :
page 269 3.10.3.3 DRQ TYPE
port 4 => I2S/PCM1-RX /  I2S/PCM1-TX
Same for A64
But indeed it's not mapped for H5.

I will fix the yaml for H3/H5 but not for A64/H6.

Clement
