[PATCH 1/6] ASoC: meson: axg-tdm-interface: fix mclk setup without mclk-fs

[Jerome Brunet]

By default, when mclk-fs is not provided, the tdm-interface driver
requests an MCLK that is 4x the bit clock, SCLK.

However there is no justification for this:

* If the codec needs MCLK for its operation, mclk-fs is expected to be set
  according to the codec requirements.
* If the codec does not need MCLK the minimum is 2 * SCLK, because this is
  minimum the divider between SCLK and MCLK can do.

Multiplying by 4 may cause problems because the PLL limit may be reached
sooner than it should, so use 2x instead.

[PATCH 2/6] ASoC: meson: axg-tdm-interface: add frame rate constraint

[Jerome Brunet]

According to Amlogic datasheets for the SoCs supported by this driver, the
maximum bit clock rate is 100MHz.

The tdm interface allows the rates listed by the DAI driver, regardless of
the number slots or their width. However, these will impact the bit clock
rate.

Hitting the 100MHz limit is very unlikely for most use cases but it is
possible.

For example with 32 slots / 32 bits wide, the maximum rate is no longer
384kHz but ~96kHz.

Add the constraint accordingly if the component is not already active.
If it is active, the rate is already constrained by the first stream rate.

[PATCH 3/6] ASoC: meson: axg-tdm-interface: update error format error traces

[Jerome Brunet]

ASoC stopped using CBS_CFS and CBM_CFM a few years ago but the traces in
the amlogic tdm interface driver did not follow.

Update this to match the new format names

[PATCH 4/6] ASoC: meson: axg-spdifin: use max width for rate detection

[Jerome Brunet]

Use maximum width between 2 edges to setup spdifin thresholds
and detect the input sample rate. This comes from Amlogic SDK and
seems to be marginally more reliable than minimum width.

This is done to align with a future eARC support.
No issue was reported with minimum width so far, this is considered
to be an update so no Fixes tag is set.

[PATCH 5/6] ASoC: meson: axg-fifo: take continuous rates

[Jerome Brunet]

The rate of the stream does not matter for the fifos of the axg family.
Fifos will just push or pull data to/from the DDR according to consumption
or production of the downstream element, which is the DPCM backend.

Drop the rate list and allow continuous rates. The lower and upper rate are
set according what is known to work with the different backends

This allows the PDM input backend to also use continuous rates.

Ah, I forgot to include <linux/bitfield.h>. Thanks for letting me know.
I'll fix it

It was fine when I tested with ARCH=arm64 and the default defconfig so
most likely it got indirectly included.

Could you tell me which ARCH/defconfig triggered this ?

Probably an x86 allmodconfig.

      (no commit info)

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
