2013-11-07ASoC: wm_adsp: Fix BUG_ON() and WARN_ON() usagesTakashi Iwai1-11/+6
This patch does: - Move the sanity check with WARN_ON() in wm_adsp_region_to_reg() and remove the checks in the callers, - Fix wrong WARN_ON() usages, replaced with WARN(), - Fix unreachable or wrong BUG_ON() usages and replace with WARN_ON().

2013-08-01ASoC: wm_adsp: Sanitize parameter passingDimitris Papastamos1-15/+16
No need to hold on to the `codec' pointer. We can use the `dsp' pointer and grab all the information we need from there. This makes the parameters for the functions a bit more sane and idiomatic.

2013-07-29ASoC: wm_adsp: Simplify kcontrol handlingDimitris Papastamos1-72/+31
Get rid off the wm_coeff struct and the wm_coeff_add_kcontrol() function. We are now using the snd_soc_card_kcontrol() function to get the kcontrol pointers. No need to call into ALSA code to register the kcontrols. Signed-off-by: Dimitris Papastamos <dp@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-05-28ASoC: wm_adsp: Ensure set controls are synced on each bootDimitris Papastamos1-10/+9
Rename `dirty' to `set' as it is a bit more descriptive. A set control is any control that has been set by the user. We need to ensure that everytime we boot the DSP we sync out any controls that were set. We could at some point start keeping track of the default values of the controls to suppress some of the device I/O.

Add initial support for runtime tuning for the ADSP cores. This is achieved by exposing the coefficient configuration blocks as ALSA binary controls.

2013-04-11ASoC: wm_adsp: Add support for firmware wide coefficient blocksMark Brown1-0/+40

2013-03-29ASoC: wm_adsp: Split ADSP1 and ADSP2 firmware controlsMark Brown1-7/+19

2013-03-21ASoC: arizona: Basic support for ISRC rate selectionMark Brown1-0/+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.
