[PATCH 0/3] Add WM8580 PCM Machine driver for Samsung SoCs

[PATCH 0/3] Add WM8580 PCM Machine driver for Samsung SoCs

[Sangbeom Kim]

Hi,

This patchset is for WM8580 pcm machine driver that supports
PCM audio on SMDKC110, SMDKV210, SMDK6450, SMDK6440.
and It is tested on SMDKC110, SMDKV210, SMDKV6450.

Based on these patches WM8580 pcm machine driver supports followings:
 o Playback supports 8kHz sampling rates.
 o Capture supports 8kHz sampling rates.

This patchset contains followings 

 o To Kukjin Kim and Ben Dooks,
[PATCH 1/3] ARM: S5PV210: Add PCM audio support for WM8580
[PATCH 2/3] ARM: S5P64X0: Add PCM audio support for WM8580

 o To Jassi Brar, Mark Brown and Liam Girdwood,
[PATCH 3/3] ASoC: SAMSUNG: Add WM8580 PCM Machine driver 

This patch-set is based on 2.6.39-rc1
and WM8580 machine driver is originated by Seungwhan Youn.

Best Regards,
SB Kim (Sangbeom Kim)

[PATCH 1/3] ARM: S5PV210: Add PCM audio support for WM8580

[Sangbeom Kim]

This patch add pcm audio configuration for SMDKV210 and SMDKC110.
Platform device and pcm clock initialization code is added.

[alsa-devel][PATCH 3/3] SoC: SAMSUNG: Add WM8580 PCM Machine driver

[Sangbeom Kim]

This patch add WM8580 PCM machine driver to support PCM audio
on SMDKC110, SMDKV210, SMDK6450, SMDK6440 boards.
Playback and Capture supports 8kHz sampling rates.
and It is tested on SMDKC110, SMDKV210, SMDK6450.

What is the purpose of this variable?  Just the config for the machine
should be enough.

These changes all look reasonable but they're unrelated to adding the
machine driver and should be split out.

Similarly here, this is a bug fix so should be merged for 2.6.39.

Please use snd_soc_register_card() for new machines rather than the
soc-audio device.  Otherwise the actual driver itself looks good.

Ok, I will remove it and use machine config.

Ok, I will split out.

I will submit another bug fix patch for this.

Ok I will apply it.

IIRC the PCM DAI is connected to Secondary i/f of WM8580
on some SMDKs. Isn't it smdk6410 ?

Yes, Your remember is right. SMDK6410 has WM8580 PCM DAI.
But, In this time, I couldn't test on SMDK6410.
After testing on SMDK6410, I will submit related patch.

Thanks and regards,
