| * ASoC: wm_adsp: Split ADSP1 and ADSP2 firmware controlsMark Brown2013-03-291-7/+19
| | | | | | | | | | | | | | | | Now that we have regular register mapped controls we should be splitting the control sets for ADSP1 and ADSP2 as the register maps are not identical. Do that. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
| * ASoC: arizona: Basic support for ISRC rate selectionMark Brown2013-03-211-0/+24
| | | | | | | | | | | | | | | | | | | | Since ASoC does not yet really have the framework features needed to support propagating sample rates through the device well yet implement basic support for the ISRCs equivalent to that we currently have for the ASRCs. The user can opt for 8kHz or 16kHz as the rate for the DSP blocks in addition to the main audio rate, these being the primary use cases.

* ASoC: adsp: Add ADSP base supportMark Brown2012-10-281-0/+571
Many current Wolfson devices feature DSPs based around an architecture known as ADSP. Since there is a lot of commonality in the system integration of these devices a common library will be used to provide support for them. This version provides equivalent support for ADSP1 to that currently included in the WM2200 driver. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
