[PATCH 0/6] ASoC: meson: add g12a SoC family support

[Jerome Brunet]

The Amlogic g12a SoC family audio subsystem derives from the one found
in the axg SoC family.

To add support for the g12a in the existing elements, this patchset deals
with following differences compared to the axg family:
 * fifos must set an initial start address within the buffer.
   The fifo pointer shall be reset to this address on startup.
 * frddrs may now play on up to 3 output interfaces simultaneously.
 * tdmout formatters need a different signal skew offset.

[PATCH 1/6] ASoC: meson: add g12a compatibles

[Jerome Brunet]

Add new compatible strings for the g12a devices.
Audio wise, the g12a is fairly to close to the axg, yet some differences
need to be handled.

[PATCH 2/6] ASoC: meson: axg-fifo: add g12a support

[Jerome Brunet]

The g12a fifos gained the ability to set the initial address of the
pointer within the buffer, instead of defaulting to the buffer start
address.

It is not very useful to us (yet) but we need to put a copy the buffer
start address in the related register for the fifo to work properly on the
g12a SoC family

[PATCH 3/6] ASoC: meson: axg-toddr: add g12a support

[Jerome Brunet]

Since the g12a SoC fifo can set the fifo initial start address, we must
make sure to actually reset the write pointer to this address when
starting a capture.

[PATCH 4/6] ASoC: meson: axg-frddr: add g12a support

[Jerome Brunet]

On the axg, frddr could only be connected to 1 downstream element, so the
playback was possible on 1 interface only at a time.

On the g12a, the frddr may connect and wait for the request of up to 3
downstream elements. With this, it possible for single playback to be
played on several interfaces at the same time.

Like the toddr fifo, the g12a frddr also need to take care of resetting
the read pointer to the initial fifo address when preparing a playback.

[PATCH 5/6] ASoC: meson: axg-tdm-formatter: rework quirks settings

[Jerome Brunet]

The g12a tdmout requires a different signal skew offset than the axg.
With this change, the skew offset is added as a parameter of the tdm
formatters to prepare the addition of the g12a support.

Applied "ASoC: meson: axg-tdmout: add g12a support" to the asoc tree

[Mark Brown]

The patch

   ASoC: meson: axg-tdmout: add g12a support

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Applied "ASoC: meson: axg-frddr: add g12a support" to the asoc tree

[Mark Brown]

The patch

   ASoC: meson: axg-frddr: add g12a support

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Subject: [PATCH] ASoC: meson: axg-frddr: add g12a support

On the axg, frddr could only be connected to 1 downstream element, so the
playback was possible on 1 interface only at a time.

On the g12a, the frddr may connect and wait for the request of up to 3
downstream elements. With this, it possible for single playback to be
played on several interfaces at the same time.

Like the toddr fifo, the g12a frddr also need to take care of resetting
the read pointer to the initial fifo address when preparing a playback.

Since the g12a SoC fifo can set the fifo initial start address, we must

Subject: [PATCH] ASoC: meson: axg-fifo: add g12a support

The g12a fifos gained the ability to set the initial address of the
pointer within the buffer, instead of defaulting to the buffer start
address.

It is not very useful to us (yet) but we need to put a copy the buffer
start address in the related register for the fifo to work properly on the
g12a SoC family

Subject: [PATCH] ASoC: meson: add g12a compatibles

Add new compatible strings for the g12a devices.
Audio wise, the g12a is fairly to close to the axg, yet some differences
need to be handled.
