* ASoC: kirkwood: implement NO_PERIOD_WAKEUP supportRussell King2014-06-282-8/+12
| | | | | | | | | | Permit ALSA to run without hardware interrupts from the audio interface. Instead, ALSA will use a kernel timer to decide when to check the buffer state, resulting in a lighter workload for the CPU.

| | | | | | | | | | There is no hardware restriction requiring a minimum of 8 periods, or a minimum of 2048 bytes in a period.

| | | | | | | | | | | | We still see the occasional timeout waiting for busy to clear. As the spec is contradictory, and we know that the current implementation doesn't work, try an alternative interpretation from the spec. This one appears to work - I have yet to find any issue with it during my testing over several months.

| | | | | | | | | | | The spec requires that the mute bits must be set while the channel is disabled. Ensure that this is the case by providing a helper which ensures that the appropriate mute bit is set while the enable bit is clear.

| | | | | | | | | | | Since we wish to disable capture inputs for some formats, we need to ensure that we clear the enable bits in our cached record control register.

| |/ | | | | | | | | | | | | | | | | | | | | The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.

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() ...
| * DMA-API: sound: fix dma mask handling in a lot of driversRussell King2013-10-311-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: kirkwood: change the compatible string of the kirkwood-i2s driverThomas Petazzoni2013-09-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The compatible string of the kirkwood-i2s driver was chosen as "marvell,mvebu-audio". Using such a compatible string is not a good idea, since "mvebu" is the name of a large family of SOCs, in which new, unknown SOCs will be coming in the future. It is therefore impossible to know what will be evolutions of this hardware block in the next generations of the SOCs. For this reason, the recommandation for compatible strings of on-SOCs devices has always been to use the name of the oldest SOC that has the hardware block. New SOCs that have an exactly compatible hardware block can reference it using the same compatible string. See [1], [2] and [3] for various cases were this suggestion was made, including from Rob Herring, a Device Tree binding maintainer. As an example, there are already small differences between current generations: * On Kirkwood, only one interrupt is used for audio. * On Dove, two interrupts are used, one for audio data and one for error reporting. In the near future, I'll be adding audio support to Armada 370, which allows has the same hardware block (but maybe with minor variants). Therefore, this patch changes the driver to accept "marvell,kirkwood-audio" and "marvell,dove-audio" as compatible strings instead of the too-generic "marvell,mvebu-audio". The reason for the two different compatible strings is the difference in the number of interrupts used by the two SOCs for audio. This Device Tree binding has never been part of a Linux kernel stable release so far, so it can be changed now without breaking backward compatibility.

| | | | | | | | | | | | | | | | The kirkwood_dma_ops struct is not used outside of kirkwood-dma.c, so make it static. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: Convert to devm_ioremap_resource()Thierry Reding2013-01-221-5/+3
| | | | | | | | | | | | | Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

* ASoC: kirkwood-dma: remove channel restrictionsRussell King2012-11-211-2/+4
| | | | | | | | | | | | | This is part of a patch found in Rabeeh Khoury's git tree for the cubox. With SPDIF passthrough, we are not restricted to just two channels of audio; we can support however many channels the non-audio stream can itself support. In any case, kirkwood-dma is not involved in the format selection. So yet rid of this restriction.
