2013-01-23ASoC: wm_adsp: Correct handling of some coefficeint blocksMark Brown1-1/+2
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-22ASoC: wm_adsp: Release firmware on errorCharles Keepax1-1/+1
This patch correctly releases the firmware if the magic string in the firmware header does not match. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-21ASoC: wm_adsp: Provide explicit trace of coefficient writesMark Brown1-0/+3
Helpful for debugging. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-01-20ASoC: wm_adsp: Use GFP_DMA for algorithm readbackMark Brown1-1/+1
Normally kmalloc() returns things that are DMA safe so not visible on all platforms but we do need to explicitly request DMA safe memory. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-20ASoC: wm_adsp: Use GFP_DMA for things that may be DMAedMark Brown1-2/+2
Normally kmalloc() returns things that are DMA safe so not visible on all platforms but we do need to explicitly request DMA safe memory. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-20ASoC: wm_adsp: Make region identification errors more informativeMark Brown1-1/+2
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-18ASoC: wm_adsp: Set ADSP1 clock rate to match sys clockChris Rattray1-0/+33
Sets the ADSP1 clock rate to match the system clock rate. To support this the codec driver provides details of register containing the system clock control bits. Signed-off-by: Chris Rattray <crattray@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-18ASoC: wm_adsp: Implement support for coefficeint file format 1Mark Brown1-5/+15
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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-16ASoC: wm_adsp: Add initialisation function for ADSP1Mark Brown1-0/+8
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-12ASoC: wm_adsp: Add basic firmware selection supportMark Brown1-2/+73
There are many firmwares available for ADSP devices. Add basic support for selecting between them, including a couple of feature sets in the set of available firmware to start off with. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-09ASoC: wm_adsp: Implement support for algorithm-specific coefficient blocksMark Brown1-4/+110
WMDR coefficient files can specify coefficients in terms of algorithm specific data regions. Record the start addresses of these regions while parsing the algorithms and then use them to handle coefficients with these formats. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-09ASoC: wm_asdp: Validate sanity of algorithm countMark Brown1-2/+15
If we run into I/O problems the algorithm count may be crazy, validate it before we proceed and dump the read data for diagnostic purposes. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2013-01-09ASoC: wm_adsp: Add support for parsing algorithmsMark Brown1-0/+143
ADSP devices report information on the algorithms loaded on them. Parse this data and use it to allow coefficients to be configured for specific algorithms. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2013-01-07ASoC: wm_adsp: Ensure that block writes are from DMA aligned addressesMark Brown1-1/+22
Otherwise we won't run correctly on systems that require this for larger data transfers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-12-09Merge remote-tracking branch 'asoc/topic/arizona' into asoc-nextMark Brown1-0/+33
2012-12-02ASoC: adsp: Set DSP clock rate to SYSCLK rateMark Brown1-0/+22
For simplicity always run the DSP at the SYSCLK rate. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-12-02ASoC: adsp: Keep ADSP2 memory powered off when not in useMark Brown1-0/+11
Turn off the ADSP memory when we aren't using it, saving a small amount of power. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-29ASoC: arizona: Add parenthesesMark Brown1-1/+1
Some compiler versions complain. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-29ASoC: wm_adsp: Set the core enable as well as start bit for ADSP2Mark Brown1-3/+5
Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-28ASoC: wm_adsp: Enable DVFS for ADSP2Mark Brown1-2/+95
Some ADSP devices can make use of DVFS to optimise power consumption depending on the operating frequency of the DSP core. Implement support for this in the generic ADSP code. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-10-28ASoC: adsp: Add ADSP base supportMark Brown1-0/+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>
