* ASoC: davinci-mcasp: Move private struct definition to source filePeter Ujfalusi2013-12-102-35/+30Star

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/+3Star
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Most of it is restored by running a normal audio stream startup, but the DAI format is left unset as that's configured on the audio device creation.

| * | ASoC: davinci-mcasp: Add support for multichannel playbackMichal Bachraty2013-03-043-15/+68
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Davinci McASP has support for I2S multichannel playback. For I2S playback/receive, each serializer is capable to play 2 channels (L/R) audio data.Serializer function (Playback-receive-none) is configured in DT, depending on hardware specification. It is possible to play less channels than configured in DT. For that purpose,only specific number of active serializers are enabled. McASP FIFO need to have DMA transfer Bcnt set to number of enabled serializers, otherwise no data are transfered to McASP and Alsa generates "DMA/IRQ playback write error (DMA or IRQ trouble?)" error. For TDM mode, McASP is capable to play or receive 32 channels for one serializer. McAsp has support for max 16 serializer, therefore max channels is 32 * 8.

| * ASoC: tlv320aic3x: Convert mic bias to a supply widgetHebbar Gururaja2013-02-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert MicBias widgets to supply widget. On tlv320aic3x, Mic bias power on/off shares the same register bits with output mic bias voltage. So, when power on mic bias, we need reclaim it to voltage value. Provide a new platform data so that the micbias voltage can be sent according to board requirement. Now since tlv320aic3x codec driver is DT aware, update dt files and functions to handle this new "micbias-vg" platform data. Because of sharing of bits, when enabling the micbias, voltage also needs to be updated. So use SND_SOC_DAPM_POST_PMU & SND_SOC_DAPM_PRE_PMD macro to create an event to handle this. Since micbias is converted to supply widget, updated machine drivers as well. This change is runtime tested on da850-evm with audio loopback (arecord|aplay) for confirmation.

* | ASoC: McASP: Fix data rotation for playback. Enables 24bit audio playbackMichal Bachraty2013-01-271-1/+1
|/ | | | | | | | | | | | | | u32 rotate = (32 - word_length) / 4; This implementation is wrong, but it works only for 16, or 32 bit audio data. (rotation for 16 or 32 bit is same as in code I present) Mcasp rotated data in 4 bits (max value 0x7)and then masks them . That data are sended to i2s bus. For 24 bit or 20 bit or other data formats, this code rotates data badly and you hear somethink like noise. You need to use u32 rotate = (word_length / 4) & 0x7; to proper data rotation.

* ASoC: McASP: implement a way to force BCLK/LRCLK ratiosDaniel Mack2012-12-072-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Depending on the Codec, the the BCLK/LRCLK ratio might not be freely chosen by the CPU DAI. For example, some Codec might want to be supplied with 32-bit samples for both its channels regardless of the actual audio word size the CPU sends. In such cases, the rest of the bits on the data lines must be padded with zeros: _______________________________ LRCLK / \ --' `---------- ..... BCLK ||||||||||||||||||||||||||||||||||||||||||||||| ..... DATA ____||||||||||||||||_________________|||||||||| ..... |<-- data -->|<-- pads --> | This patch adds a new clock divider to configure the BCLK/LRCLK ratio. If the machine code uses that divider, the driver uses the specified value, instead of deriving that information from the audio word size. Otherwise, the original behaviour is retained.

* ASoC: McASP: calculate values for channel sizeDaniel Mack2012-12-072-63/+10Star
| | | | | | | | | | | | | Change davinci_config_channel_size() to derive the values for XSSZ and XROT in DAVINCI_MCASP_[RT]XFMT_REG from the configured word length rather than hard-coding them in a switch/case block. Also, by directly passing the word length to davinci_config_channel_size(), we can get rid of the DAVINCI_AUDIO_WORD_* enum.
