This patch adds basic support for Mediatek AFE for MT2701 SoC.
The patch is based on broonie tree "for-next" branch.
Change since v4:
* remove SND_SOC_MEDIATEK config prompt
* fix config prompt to meaningful one for SND_SOC_MT2701_CS42448
* remove some unnecessary random space change
Change since v3:
* fix comments style.
Change since v2:
* fix comments style.
* replace EXPORT_SYMBOL with EXPORT_SYMBOL_GPL
* reduce debug message
* move mutex lock for irq-allocated to AFE struct
* remove func mtk_simple_isr and call snd_pcm_period_elapsed directly
* mt2701 driver probe will fail if clock initial error
* fix dapm on/off switch control naming
Change since v1:
implement common private structure, fe dai and platform driver.
let mt8173 and mt2701 use the common structure.
Garlic Tseng (9):
ASoC: mediatek: Refine mt8173 driver and change config option
ASoC: mediatek: implement mediatek common structure
ASoC: mediatek: let mt8173 use mediatek common structure
ASoC: mediatek: add documents for mt2701
ASoC: mediatek: add structure define and clock control for 2701
ASoC: mediatek: add mt2701 platform driver implementation.
ASoC: bt-sco: extend rate and add a general compatible string
ASoC: mediatek: add BT implementation
ASoC: mediatek: Add mt2701-cs42448 driver and config option.

Add mt2701 platform driver implementation for playback and capture.
The implement follow DAPM structure (memory interface as FE and I2S
as BE).
Because of the hardware design, i2s out required to be enabled when
we need to enable i2s in. This patch includes the implementation.

Add mt2701 platform driver implementation for playback and capture.
The implement follow DAPM structure (memory interface as FE and I2S
as BE).
Because of the hardware design, i2s out required to be enabled when
we need to enable i2s in. This patch includes the implementation.

* [alsa-devel] [PATCH v5 6/9] ASoC: mediatek: add mt2701 platform driver implementation.

To: linux-arm-kernel
Add mt2701 platform driver implementation for playback and capture.
The implement follow DAPM structure (memory interface as FE and I2S
as BE).
Because of the hardware design, i2s out required to be enabled when
we need to enable i2s in. This patch includes the implementation.

Why are we adding a set_clkdiv() operation? I would expect the driver

Especially in the case where we're configuring LRCLK, that's trivial
when we know the sample rate which we have to know anyway.

This will claim that we support 16k on existing systems which we clearly
don't. It also seems unwise to advertise multiple rates when we've no
way to configure the rates... how does the BT controller figure out
what the sample rate is?

* Applied "ASoC: mediatek: let mt8173 use mediatek common structure" to the asoc tree

The patch
ASoC: mediatek: let mt8173 use mediatek common structure
has been applied to the asoc tree at
git://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.

The patch
ASoC: mediatek: let mt8173 use mediatek common structure
has been applied to the asoc tree at
git://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

The patch
ASoC: mediatek: let mt8173 use mediatek common structure
has been applied to the asoc tree at
git://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

The codec driver is a dummy driver for bt device and actually do
nothing. The user-space will control both bt part and alsa part (at
least in mt2701 platform). Yes the sound/soc/codecs/bt-sco.c was only
support 8k and was already there before the patch, but I think it might
be ok to extend it to 16k without any side effect.
If you worry about some potential risk (I don't see any) maybe we have
to develop another dummy bt-sco codec driver which support both 8k and
16k?

Oh... actually I want to say 'div_mclk_over_bck' and 'div_bck_over_lrck'
I'll fix the naming if we decide to reserve the set_clkdiv() operation.
For div_bck_over_lrck, yes we only support bck = 64fs now so I'll remove
it. Maybe in the future we'll allow bck = 32fs for some board and I'll
send patch on that time.
For div_mclk_over_bck, mt2635 can offer 128fs and 256fs mclk to codec,
and it depends on the board so I tend to let machine driver configure
it. However, maybe changing it to div_mclk_over_lrck will be better.
I'll do the change.
BTW, some patch is applied for the patchset so I need not to send the
new version but send another patchset, right?

Oh... actually I want to say 'div_mclk_over_bck' and 'div_bck_over_lrck'
I'll fix the naming if we decide to reserve the set_clkdiv() operation.
For div_bck_over_lrck, yes we only support bck = 64fs now so I'll remove
it. Maybe in the future we'll allow bck = 32fs for some board and I'll
send patch on that time.
For div_mclk_over_bck, mt2635 can offer 128fs and 256fs mclk to codec,
and it depends on the board so I tend to let machine driver configure
it. However, maybe changing it to div_mclk_over_lrck will be better.
I'll do the change.
BTW, some patch is applied for the patchset so I need not to send the
new version but send another patchset, right?

Ah! If someone whose bluetooth modules only support 8k use the driver,
they might be broken, right? Maybe we can add another snd_soc_dai_driver
which can support both 8k and 16k.

Yes, that'd be fine - it could be the same driver and register different
parameters depending on config/compatible.

Could we also make this driver directly configurable from Kconfig,
and not just selected by platforms (currently Samsung) or by building
all coddecs?

Hi Mark, I recognize that we can set mclk by set_sysclk, fix bck to 64fs
and let lrck be the same as sample rate so yes we don't need set_clkdiv.
Thanks for comment, I'll fix that in the next patch.
