[PATCH v9 00/14] Add Allwinner H3/H5/H6/A64 HDMI audio

[PATCH v9 00/14] Add Allwinner H3/H5/H6/A64 HDMI audio

[Clément Péron]

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 we 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 :/.

Regards,
Clement

[PATCH v9 01/14] ASoC: sun4i-i2s: Change set_chan_cfg() params

[Clément Péron]

As slots and slot_width can be set manually using set_tdm().
These values are then kept in sun4i_i2s struct.
So we need to check if these values are set or not.

This is not done actually and will trigger a bug.
For example, if we set to the simple soundcard in the device-tree
dai-tdm-slot-width = <32> and then start a stream using S16_LE,
currently we would calculate BCLK for 32-bit slots, but program
lrck_period for 16-bit slots, making the sample rate double what we
expected.

To fix this, we need to check if these values are set or not but as
this logic is already done by the caller. Avoid duplicating this
logic and just pass the required values as params to set_chan_cfg().

Aren't I2S, LEFT_J and RIGHT_J pretty much the same in terms of lrclk 
rate/period? the only thing that can change is the polarity, no?

Not sure why it's handled differently here?

I just had a look at the User Manual for H3 and H6 and I didn't find
any reason why LEFT_J and RIGHT_J should be computed in a different
way as I2S.

Also the commit introducing this doesn't mention it.
7ae7834ec446 ("ASoC: sun4i-i2s: Add support for DSP formats")

I can't test it with my board but if nobody complains about it, I will
introduce a fix for this in the next version and change this also for
H6.

Thanks for your review,
Clement

Yes, and the manual explicitly groups LEFT_J and RIGHT_J with I2S when
describing this field:

   PCM Mode: Number of BCLKs within (Left + Right) channel width.
   I2S/Left-Justified/Right-Justified Mode: Number of BCLKs within each
individual channel width(Left or Right)

So I agree that the code is wrong here.

Samuel

[PATCH v9 02/14] ASoC: sun4i-i2s: Add support for H6 I2S

[Clément Péron]

From: Jernej Skrabec <jernej.skrabec@siol.net>

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

[PATCH v9 02/14] ASoC: sun4i-i2s: Add support for H6 I2S

[Clément Péron]

From: Jernej Skrabec <jernej.skrabec@siol.net>

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

[Clément Péron]

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.

[PATCH v9 04/14] ASoC: sun4i-i2s: Set sign extend sample

[Clément Péron]

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.

Because SUN4I_I2S_FIFO_CTRL_REG is volatile, writes done while the

[PATCH v9 08/14] ASoC: sun4i-i2s: fix coding-style for callback definition

[Clément Péron]

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.

[PATCH v9 09/14] dt-bindings: ASoC: sun4i-i2s: Add H6 compatible

[Clément Péron]

From: Jernej Skrabec <jernej.skrabec@siol.net>

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

[PATCH v9 13/14] dt-bindings: sound: sun4i-i2s: Document H3 with missing RX channel possibility

[Clément Péron]

Like A83T the Allwinner H3 doesn't have the DMA reception available for
some audio interfaces.

As it's already documented for A83T convert this to an enum and add the H3
interface.
