2014-03-04ASoC: n810: fix init with DT bootAaro Koskinen
Since 3.14-rc1 only DT boot has been supported on N810, so this file fails to init. Make a minimal fix to retain functionality. This file should be properly converted to DT in longer term. There seems to be still other unresolved issues with N810 audio support, but this patch is needed at minimum as otherwise the machine driver probing would completely fail.

2013-12-24ASoC: omap: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen
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.

2013-12-02ASoC: omap: n810: Convert to clk_prepare_enable/clk_disable_unprepareJarkko Nikula
N810 audio driver has stopped working at some point. Probably when OMAP2 was converted to common clock framework since now call to clk_enable dumps the stack trace in drivers/clk/clk.c: __clk_enable() due clk->prepare_count is zero. Fix this by converting clk_enable/_disable calls to those that take care of clock prepare/unprepare. I'm not queueing this to linux-stable since OMAP2 common clock framework conversion in commit ed1ebc4948fd ("ARM: OMAP2: clock: Convert to common clk") happened before N810 was really usable in mainline and user base for N810 is anyway small. Potential linux-stable candidates are only those after commit 3d3a6d18abc6 ("watchdog: introduce retu_wdt driver").

All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-11-14Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. 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() ...

2013-10-31DMA-API: sound: fix dma mask handling in a lot of driversRussell King
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.

2013-04-17ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optionalLars-Peter Clausen
Refactor the dmaengine PCM library to allow the DMA channel to be requested before opening a PCM substream. snd_dmaengine_pcm_open() now expects a DMA channel instead of a filter function and filter parameter as its parameters. snd_dmaengine_pcm_close() is updated to not release the DMA channel. This allows a dmaengine based PCM driver to request its channels before the substream is opened. The patch also introduces two new functions, snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan(), which have the same signature and behaviour of the old snd_dmaengine_pcm_{open,close}() and internally use the new variants of these functions. All users of snd_dmaengine_pcm_{open,close}() are updated to use snd_dmaengine_pcm_open_request_chan() and snd_dmaengine_pcm_close_release_chan().

2013-03-20ASoC: omap-mcpdm: Fix for full duplex audio use casePeter Ujfalusi
Due to HW limitation within OMAP McPDM IP uplink and downlink need to be started at the same time. This causes issues when we have two streams running, for example: arecord | aplay In this case the playback stream would have no channels enabled since at the capture start we are not aware that a playback is going to start. The workaround is to configure the other direction to stereo when the first stream is started. When the second stream is coming we check the new stream's number of channels against the pre-configured channels. If it does not match we stop and restart McPDM to update the configuration. This might result a small pop. If the coming stream is a match we do nothing in the McPDM driver. This workaround can handle most use cases without the need to restart McPDM.
