[PATCH 0/5] ARM: shmobile: bockw: add Sound support

[Kuninori Morimoto]

Hi Simon

These patches add R-Car sound support on Bock-W board.
It enables PIO transfer only at this point, because
 1) PIO settings is the most easy basic settings
 2) HPB-DMAC is still not enabled on r8a7778

R-Car sound driver is already supporting DMA transfer on ASoC (= Mark's) branch.
So, it is easy to support DMA transfer if r8a7778 has HPB-DMAC support.

To enable R-Car sound on Bock-W board, ASoC branch mergeing is required

As per my separate email in response to "sh-pfc: r8a7778: add SRU/SSI pin
support", it seems that patch should be reviewed by Laurent and ideally
taken through Linus's tree.

With regards to the remaining patches, Magnus, could you cast an eye over them?

Re: [PATCH 0/5 v2] ARM: shmobile: bockw: add Sound support

[Kuninori Morimoto]

Hi Simon, Laurent

These are v2 of R-Car sound support on Bock-W board.

It enables PIO transfer only at this point, because
 1) PIO settings is the most easy basic settings
 2) HPB-DMAC is still not enabled on r8a7778

R-Car sound driver is already supporting DMA transfer on ASoC (= Mark's) branch.
So, it is easy to support DMA transfer if r8a7778 has HPB-DMAC support.

To enable R-Car sound on Bock-W board, ASoC branch mergeing is required

[PATCH 4/5 v2] ARM: shmobile: bockw: add R-Car sound support (PIO)

[Kuninori Morimoto]

This patch enables R-Car sound,
AK4643 (CN19) and AK4554 (CN20/CN21) codec chip
on Bock-W.

But, it supports PIO transfer only at this point.
User can check sound settings (Dip-switch/PFC etc)
via this patch, but will get under/over flow error
when playback/capture.
Because PIO transfer via SSI will be interrupted
"sampling rate" times per 1 second.

DMA transfer will be supported when HPB-DMAC was
enabled on r8a7778.

You will notice strange ALSA sound card HW
numbering on Bock-W board.
This came from AK4554 strange format on playback/capture.
The format on playback/capture is same on "normal" codec chip,
but AK4554 was different.
Because of that, AK4554 playback/capture are
registered as a different sound card.

    Looks like Vinod Koul has queued HPP-DMAC for 3.12-rc1 in his 'next' 
branch, so you can start looking at addign DMA for 3.13. I'll submit the 
patches enabling HPB-DMAC in {marzen|bockw}_defconfig later...

Thanks, I have queued this up for v3.13.

There was a bit of diff-noise, please make sure I have applied it
correctly. The patch I applied is below:


From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

ARM: shmobile: bockw: add R-Car sound support (PIO)

This patch enables R-Car sound,
AK4643 (CN19) and AK4554 (CN20/CN21) codec chip
on Bock-W.

But, it supports PIO transfer only at this point.
User can check sound settings (Dip-switch/PFC etc)
via this patch, but will get under/over flow error
when playback/capture.
Because PIO transfer via SSI will be interrupted
"sampling rate" times per 1 second.

DMA transfer will be supported when HPB-DMAC was
enabled on r8a7778.

You will notice strange ALSA sound card HW
numbering on Bock-W board.
This came from AK4554 strange format on playback/capture.
The format on playback/capture is same on "normal" codec chip,
but AK4554 was different.
Because of that, AK4554 playback/capture are
registered as a different sound card.

Unfortunately I didn't read your cover email carefully before queuing this up.
I now see that it has dependencies that aren't present in v3.11-rc and
thus I have temporarily dropped it.

It seems to me that the dependencies could be provided by
the topic/car branch of
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git.

Morimoto-san, is this correct?
If so, Mark, would it be possible for you to provide topic/car
or similar as stable branch for me to use as a base?
My intention is to queue these up for v3.13.

Alternatively, if the dependencies are likely to
appear in v3.12-rc1 or v3.12-rc2 then I can just wait until
they are available there.
