[PATCH v2 00/20] Add Allwinner H3/H5/H6/A64 HDMI audio

[PATCH v2 00/20] Add Allwinner H3/H5/H6/A64 HDMI audio

[Clément Péron]

Hi,

Regarding the I2S LRCK polarity, Maxime Ripard test it and found that
the LRCK is fine: https://lkml.org/lkml/2020/7/29/581.
So the patch introduce this modification has been reverted.

I have tested this on Allwinner H6 but this should be tested on older
platform like sun4i family.

Regards,
Clement

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

[PATCH v2 01/20] Revert "ASoC: sun4i-i2s: Fix the LRCK polarity"

[Clément Péron]

This reverts commit dd657eae8164f7e4bafe8b875031a7c6c50646a9.

There was a misinterpretation of the analysis using a scope.
After rechecking this using a logical analyzer the LRCK polarity is
fine.

[PATCH v2 03/20] ASoC: sun4i-i2s: Adjust LRCLK width

[Clément Péron]

From: Marcus Cooper <codekipper@gmail.com>

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.

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

[PATCH v2 05/20] 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.

[Clément Péron]

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.

Yes, it's fine indeed, so there's no need to change anything?

These cases don't match the documentation: LEFT_J and RIGHT_J are documented to
behave like I2S (lrck_period == slot_width), not like DSP_A/B (lrck_period ==
slot_width * slots).

Here, i2s->slot_width is the number of bits for each slot, but in PCM mode, you
need to multiply by the number of slots, like above.

Also, there is already logic in sun4i_i2s_hw_params to use i2s->slot_width and
i2s->slots. You could avoid the duplication by passing slot_width/slots as
parameters to set_chan_cfg.

Samuel

Same as patch 2, this duplicates logic in sun4i_i2s_hw_params, and would need to
be multiplied by `slots` for PCM (DSP_A/B) mode.
