[PATCH 0/5] ASoC: Fix smdk64xx-wm8580 problems

[PATCH 0/5] ASoC: Fix smdk64xx-wm8580 problems

[Seungwhan Youn]

Hi,

This patch serise fix some problems in smdk64xx board when it use
I2S with wm8580.

 o ADC source clock setting is set to use MCLK, It makes that
   wm8580 cannot make BCLK and LRCLK for playback and capture.
 o When application set some sampling freq. - 8kHz, 11.025kHz,
   audio doesn't work correctly with broken sound. Because
   wm8580 always set BCLK_RATE and LRCLK_RATE as a default value
   , BCLK_RATE - 256fs and LRCLK_RATE - 64 BCLKs per LRCLK. So,
   BCLK_RATE and LRCLK_RATE setting on wm8580 is not match to
   make these sampling freq. on wm8580 master mode.

So, to solve these problems, this patch apply followings:

 o Support ADC source clock setting on wm8580.
 o Enable to select BCLK_RATE and LRCLK_RATE value on wm8580.
 o Fix smdk-wm8580 machine code to support new features of wm8580.


The following patch series contains:

[PATCH 1/5] ASoC: wm8580: Add to support ADC clock source setting
[PATCH 2/5] ASoC: S3C64XX: Add ADC source clock setting
[PATCH 3/5] ASoC: wm8580: Fix Master Mode BCLK rates names
[PATCH 4/5] ASoC: wm8580: Add to support Master Mode Rates
[PATCH 5/5] ASoC: S3C64XX: Fix to support BCLK, LRCLK rates setting

Thanks,

Claude

[PATCH 1/5] ASoC: wm8580: Add to support ADC clock source setting

[Seungwhan Youn]

This patch adds to support additional ADC clock source setting
with R8 register for CLKSRC on wm8580.

This is OK. Though I don't remember why it wasn't accepted when
I submitted a few months ago.

IIRC it was part of a larger patch or patch series which had other

Yes you are right, seems I forgot to resubmit. My bad.

This isn't a patch for S3C64xx, this is a patch for the SMDK boards.

Can I go-ahead this ADC_MCLK patches? or will you have a plan to
handle this also?

Not really much point if we do the clocking properly - it changes over
to specifying the clock to via set_sysclk() so there's a code change
implied.

[PATCH 3/5] ASoC: wm8580: Fix Master Mode BCLK rates names

[Seungwhan Youn]

This patch fix BCLK rates name from old manual. As a recently
wm8580 manual (Rel. March 2009, Rev 4.7), wm8580 supports 4
BCLK rates, 64, 32, 16 and System Clock per LRCLK. So, this
patch apply to match BCLK rates with manual.

Again.... http://mailman.alsa-project.org/pipermail/alsa-devel/2009-September/021005.html

Also IMO, WM8580_MCLKRATIO and  WM8580_BCLKRATIO sound better
than WM8580_LRCLK_RATE and WM8580_BCLK_RATE resp. That is if they
are to be accepted.

When I write this code, I also think that name 'WM8580_MCLKRATIO' and
'WM8580_BCLKTRATIO'. But I think that 'WM8580_LRCLK_RATE' and
'WM8580_BCLK_RATE' is better because of these are named after wm8580
user manual, to avoid to be confused another guy who see this code
with wm8580 manual. If other guys think same as you, I'm ready to
modify this. :)


Thanks for your opinion. :)

[PATCH 5/5] ASoC: S3C64XX: Fix to support BCLK, LRCLK rates setting

[Seungwhan Youn]

This patch fix to support BCLK and LRCLK rates setting as
wm8580 Master mode. After apply this patch, LRCLK and BCLK
signal appears correctly from wm8580 in some freq., 8kHz
and 11.025kHz, on SMDK board.

is what I meant a few days ago when I said it should be done properly.

Also, I am not sure if we can do without setting RFS,BFS on CPU side
even in slave mode. We need to confirm.

I see, if Mark's opinion is same as before, I think I can try to make
another patch for it. :)

Okay, I agree to confirm this at the H/W design point of view.

I will look at this myself, the major blocker on doing so had been that
for many kernel releases it was not possible to use the IISv4 interface
since the support for the IISv4 main clock didn't get merged so every
time I spent any time on this it was all consumed implementing that and
resubmitting changes for that.  That appears to be sorted in at least
2.6.34 so I can now run tests much more easily.
