* ASoC: davinci-mcasp: Fix bit clock polarity settingsPeter Ujfalusi2014-04-081-3/+3
| | | | | | | | IB_NF, NB_IF and IB_IF configured the bc polarity incorrectly. The receive polarity was set to the same edge as the TX in these cases. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: davinci-mcasp: Provide correct filter_data for dmaengine for non-DT bootPeter Ujfalusi2014-03-171-5/+16
| | | | | | | | | | When we boot with non-DT mode the damengine will need the channel number and a filter function in order to get the channel. The filter_data is filled in the DAI driver while the filter_function will be provided by the edma-pcm driver.

| | | | | | | | | | | Platform driver glue for SoC using eDMA3 to use dmaengine PCM. The maximum number of periods need to be limited to 19 since the edma dmaengine driver limits the paRAM slot use for audio at in cyclic mode.

| | | | | | | | | | | | | Machine level DAPM widgets and routes should be registered in the card's DAPM context, rather than in the CODEC's context. While we are at it also drop the snd_soc_dapm_enable_pin() calls, since pins are enabled by default and also turn the snd_soc_dapm_disable_pin() calls into snd_soc_dapm_nc_pin() calls for unconnected pins.

Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code sequence is unsafe in modules: static u64 mask = DMA_BIT_MASK(something); ... if (!dev->dma_mask) dev->dma_mask = &mask; as if a module is reloaded, the mask will be pointing at the original module's mask address, and this can lead to oopses. Moreover, they all follow this with: if (!dev->coherent_dma_mask) dev->coherent_dma_mask = mask; where 'mask' is the same value as the statically defined mask, and this bypasses the architecture's check on whether the DMA mask is possible. Fix these issues by using the new dma_coerce_coherent_and_mask() function.

* | ASoC: davinci-mcasp: Remove redundant num-serializer DT parameterPeter Ujfalusi2013-10-231-17/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | The serial-dir array gives this information so there is no need to have the num-serializer property in DT description. Just ignore the property in the driver the DTS files can be updated separately without regression.

| | | | | | | | | | | | | | | | Change the model omap2-mcasp-audio in compatible property to am33xx-mcasp-audio as omap2 does not have mcasp. Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* | ASoC: davinci-mcasp: Extract DMA channels directly from DTJyri Sarha2013-10-221-14/+31
| | | | | | | | | | | | | | | | | | Extract DMA channels directly from DT as they can not be found from platform resources anymore. This is a work-around until davinci audio driver is updated to use dmaengine. Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* | ASoC: davinci-mcasp: Add location for data port registers to DTJyri Sarha2013-10-221-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a separate register location for data port registers to mcasp DT bindings. On am33xx SoCs the McASP registers are mapped trough L4 interconnect, but data port registers are also mapped trough L3 bus to a different memory location.
