* dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()Luis R. Rodriguez2016-03-091-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename dma_*_writecombine() to dma_*_wc(), so that the naming is coherent across the various write-combining APIs. Keep the old names for compatibility for a while, these can be removed at a later time. A guard is left to enable backporting of the rename, and later remove of the old mapping defines seemlessly. Build tested successfully with allmodconfig. The following Coccinelle SmPL patch was used for this simple transformation: @ rename_dma_alloc_writecombine @ expression dev, size, dma_addr, gfp; @@ -dma_alloc_writecombine(dev, size, dma_addr, gfp) +dma_alloc_wc(dev, size, dma_addr, gfp) @ rename_dma_free_writecombine @ expression dev, size, cpu_addr, dma_addr; @@ -dma_free_writecombine(dev, size, cpu_addr, dma_addr) +dma_free_wc(dev, size, cpu_addr, dma_addr) @ rename_dma_mmap_writecombine @ expression dev, vma, cpu_addr, dma_addr, size; @@ -dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size) +dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size) We also keep the old names as compatibility helpers, and guard against their definition to make backporting easier.

* ASoC: pxa: pxa-pcm-lib: switch over to snd-soc-dmaengine-pcmDaniel Mack2015-10-014-178/+50
| | | | | | | | | | | | | | | | This patch removes the old PXA DMA API usage and switches over to generic functions provided by snd-soc-dmaengine-pcm. More cleanups may be done on top of this, and some function stubs can now be removed completetly. However, the intention here was to keep the transition as small as possible. This was tested on the mioa701 pxa27x board.

* ASoC: fix broken pxa SoC supportRobert Jarzmik2015-09-161-7/+8
| | | | | | | | | | | | | | | | | | | | The previous fix of pxa library support, which was introduced to fix the library dependency, broke the previous SoC behavior, where a machine code binding pxa2xx-ac97 with a coded relied on : - sound/soc/pxa/pxa2xx-ac97.c - sound/soc/codecs/XXX.c For example, the mioa701_wm9713.c machine code is currently broken. The "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared in sound/arm/Kconfig and sound/soc/pxa/Kconfig. Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct pxa2xx-ac97 compilation.

* ASoC: pxa: remove mach header dependencyArnd Bergmann2014-05-212-2/+3
| | | | | | | | | | | | | | | | | | | | As we are moving the mmp platform towards multiplatform support, we have to stop including platform header files. This changes the pxa-ssp sound driver file to no longer depend on mach/hardware.h and mach/dma.h. The code using the definitions from those headers is actually gone already, the only thing that was still being used was the pxa_dma_desc typedef, which we can easily work around by using the normal 'struct pxa_dma_desc' name. The pxa2xx-dma driver still uses this header, so we include it explicitly there, which is ok because that is only used on pxa, not on mmp.

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/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ALSA: pxa27x: fix ac97 warm resetMike Dunn2013-01-081-1/+17
| | | | | | | | | | | | | | | | | | | | | | | This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.

Also, a timeout loop is needed to wait for the reset to complete. Tested on a palm treo 680 machine.

| * ALSA: convert sound/* to use module_platform_driver()Axel Lin2011-11-271-12/+1
| | | | | | | | | | | | | | | | | | This patch converts the drivers in sound/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* sound: irq: Remove IRQF_DISABLEDYong Zhang2011-09-222-2/+2
| | | | | | | | | | | | | | | Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.

| * ASoC: PXA: Fix oops in __pxa2xx_pcm_prepareVasily Khoruzhick2011-04-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1, but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will be called immediately, it leaves prtd->dma_ch initialized with -1, and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered via SDL. This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and cleans prtd->params, so now it works properly.

| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make Primecell driver probe functions take a const pointer to their ID tables. Drivers should never modify their ID tables in their probe handler. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AACI TRM requires the MAINCR enable bit to be held zero for two bitclk cycles plus three apb_pclk cycles. Use a delay of 1us to ensure this. Ensure that writes to MAINCR to change the addressed codec only happen when required, and that they take effect in a similar manner to the above, otherwise we seem to occasionally have stuck slot busy bits.

* | | ALSA: AACI: no need to call snd_pcm_period_elapsed() for each periodRussell King2011-01-261-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to call snd_pcm_period_elapsed() each time a period elapses - we can call it after we're done once loading/unloading the FIFO with data. ALSA works out how many periods have elapsed by reading the current pointers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Display the revision as an unsigned decimal, and display only the first 8 hex digits of the base address unless it's larger. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | | ALSA: AACI: fix channel mask selectionRussell King2011-01-261-50/+20
| | | | | | | | | | | | | | | | | | | | | | | | When double-rate mode was selected, we weren't setting the additional two channel mask bits to allow double-rate to work. Rearrange the hw_params code to allow the correct channel mask to be selected. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | | ALSA: AACI: fix number of channels for recordRussell King2011-01-251-62/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AC'97 codecs only support two channels for recording, so we shouldn't advertize that there are up to six channels available. Limit the selection of 4 and 6 channel audio to playback only. As this adds additional SNDRV_PCM_STREAM_PLAYBACK conditionals, we can combine some resulting in the elimination of __aaci_pcm_open() entirely, and making the code easier to read.

* | | ALSA: AACI: fix multiple IRQ claimingRussell King2011-01-252-9/+17
|/ / | | | | | | | | | | | | | | | | Claiming the IRQ each time a playback or capture interface is opened is wasteful; the second copy of the registered handler is identical to the first and just wastes resources. Track the number of opens and only register the handler when necessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | ALSA: AACI: fix timeout durationRussell King2011-01-251-19/+23
| | | | | | | | | | | | | | | | | | | | | | Relying on the access time of peripherals is unreliable - it depends on the speed of the CPU and the bus. On Versatile Express, these timeouts were expiring, causing the driver to fail. Add udelay(1) to ensure that they don't expire early, and adjust timeouts to give a reasonable margin over the response times. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
