[alsa-devel] [PATCH v3 0/5] ASoC: add CSR SiRFSoC sound drivers

[RongJun Ying]

From: Rongjun Ying <rongjun.ying at csr.com>

This patchset adds CSR SiRFSoC sound drivers including:
1. the platform DMA driver which will be shard by all DAI
2. the I2S CPU DAI driver
3. the USP-based PCM CPU DAI driver
4. CPU DAI and Codec driver for internal chip codec
5. the mach driver for EVB board using internal codec

-v3: 
1. Use devm_* API for driver
2. Remove the extcon stuff code
3. Calculated automatically the div vaule at runtime based on the sample rate
4. Automatically discovering the configuration of pcm hardware from the dmaengine driver
5. Add binding documents

Rongjun Ying (5):
  ASoC: sirf: add sirf platform driver which provides DMA
  ASoC: sirf: add I2S CPU DAI driver
  ASoC: usp-pcm: add CPU DAI driver for PCM simulated from USP
  ASoC: sirf-soc-inner: add drivers for both CPU and Codec DAIs
  ASoC: sirf-inner: add mach driver for SiRFSoC internal codec
