* ASoC: wm_adsp: Add support for DSP control flagsCharles Keepax2015-04-271-0/+5
| | | | | | | | The DSP control information contains various hints about the usage of the control use these when handling the control. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: wm_adsp: Add basic support for rev 1 firmware file formatCharles Keepax2015-04-271-3/+32
| | | | | | | | | | | | | | Revision one of the file format includes new algorithm and coefficient blocks which provide additional information about the controls exported by the firmware. This patch updates the processing to handle this version of the file format. Note that whilst this version of the format adds support for specifying a name for the control through the firmware file this has not been used and to keep compatibility with existing deployments no changes to the firmware control naming are made by this patch.

* ASoC: wm_adsp: Improve variable namingCharles Keepax2015-04-271-2/+2
| | | | | | | | | | | | | | | | | We have wm_adsp_region, wm_adsp_alg_region, and wmfw_region, the variables for which are all frequently called region, this can get quite confusing when reviewing the code especially given some functions are quite long. Consistently use mem for wm_adsp_regions, alg_region for wm_adsp_alg_region and region for wmfw_region. Additionally, we use a mix of adsp and dsp for pointers to the wm_adsp structure standardise this on dsp. Finally, we use algs to refer to the number of algorithms quite frequently, change this to the more descriptive n_algs.

* ASoC: wm_adsp: Implement support for coefficeint file format 1Mark Brown2013-01-181-5/+10
| | | | | | | | | | | Implement support for a new revision of the coefficeint file format for ADSP cores. Since coefficient file format 0 has not been widely deployed and is very unlikely to ever be used with this driver code support for it has been removed.

* ASoC: adsp: Add ADSP base supportMark Brown2012-10-281-0/+29
| | | | | | | | | | | | 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>
* ASoC: wm2200: Provide initial coefficient loadingMark Brown2012-10-051-0/+43
| | | | | | | | Allow a coefficient set provided using the Wolfson callibration tools to be provided along with the firmware files. Currently only coefficient files which configure absolute register addresses are supported. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: wm2200: Initial DSP supportMark Brown2012-10-051-0/+56
Support download and execution of firmwares to the DSPs on the WM2200. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
