ASoC: sirf: Add SiRF internal audio codec driver
SiRF internal audio codec is integrated in SiRF atlas6 and prima2 SoC. Features include: 1. Stereo DAC and ADC with 16-bit resolution amd 48KHz sample rate 2. Support headphone and/or speaker output 3. Integrate headphone and speaker output amp 4. Support LINE and MIC input 5. Support single ended and differential input mode Signed-off-by: Rongjun Ying <rongjun.ying@csr.com> --v5: 1. Drop all inlines. 2. Reordering the Kconfig and Makefile 3. Remove the sirf_audio_codec_reg_bits struct, use the new controls instead it. 4. Add some SND_SOC_DAPM_OUT_DRV instead of HP and SPK enable driver 5. Add audio codec clock supply instead of adc event callback 6. Fixed playback and capture can't concurrent work bug. -- .../devicetree/bindings/sound/sirf-audio-codec.txt | 17 + sound/soc/codecs/Kconfig | 5 + sound/soc/codecs/Makefile | 1 + sound/soc/codecs/sirf-audio-codec.c | 533 ++++++++++++++++++++ sound/soc/codecs/sirf-audio-codec.h | 75 +++ 5 files changed, 631 insertions(+), 0 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/sirf-audio-codec.txt create mode 100644 sound/soc/codecs/sirf-audio-codec.c create mode 100644 sound/soc/codecs/sirf-audio-codec.h Signed-off-by: Mark Brown <broonie@linaro.org>

1SiRF internal audio CODEC
2
3Required properties:
4
5 - compatible : "sirf,atlas6-audio-codec" or "sirf,prima2-audio-codec"
6
7 - reg : the register address of the device.
8
9 - clocks: the clock of SiRF internal audio codec
10
11Example:
12
13audiocodec: audiocodec@b0040000 {
14 compatible = "sirf,atlas6-audio-codec";
15 reg = <0xb0040000 0x10000>;
16 clocks = <&clks 27>;
17};
