2017-01-17ASoC: mxs-saif: fix setting master base rateJörg Krause
The SAIF base oversample rates are either 512*fs or 384*fs. An additional divider exists within the SAIF to generate sub-multiples of these two base rates if MCLK is required by the codec. * The sub-rates for the 512x base rate are: 256x, 128x, 64x, and 32x. * The sub-rates for the 384x base rate are: 192x, 96x, and 48x. Setting the base rate depending on the modulo operation with 32 and 48 give wrong results for some mclk. If mclk=18.432MHz both modulo operations results in 0. As testing the result with 32 is done first, a wrong base rate of 512*fs is set instead of the correct 384*fs. Fix this by setting the base rate depending on the calculated sub-rate.

2017-01-17ASoC: mxs-saif: fix setting SAIF1 registerJörg Krause
If SAIF0 is used in master and SAIF1 in slave mode setting the SAIF1 register in mxs_saif_set_dai_fmt() does not have any effect on the interface as the clk gate needs to be cleared before the register can be written.

Check for snd_soc_ops structures that are only stored in the ops field of a snd_soc_dai_link structure.

2016-02-05ASoC: mxs-saif: check BUSY bit in hw_params() only if not mclk_in_useMans Rullgard
If something else, typically a codec, has enabled mclk, the BUSY bit may be set when hw_params() is called without this being an error. This check thus causes intermittent failures to configure the sound device when used in such a manner. Fix this by making the test conditional on !saif->mclk_in_use.

The clk_prepare() call in hw_params() has no matching clk_unprepare(), leaving the clk with an ever-increasing prepare count. Moreover, hw_params() can be called multiple times which would again leave us with a runaway prepare count. Fix this by moving the clk_prepare() call to the startup() function and adding a shutdown() function with a matching clk_unprepare() as these operations are already correctly bracketed by soc-core.

2014-11-27ASoC: mxs-sgtl5000: Remove MCLK restrictionFabio Estevam
According to the sgtl5000 datasheet the MCLK frequency range restriction of 8 to 27 MHz only applies when the PLL is used - synchronous SYS_MCLK input mode. mxs-sgtl5000 machine sets the codec as slave, and mx28 generates MCLK in the range of 256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK input. In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the current check would return -EINVAL, which is not correct. Remove the 8 to 27MHz frequency check, since this only applies to the synchronous SYS_MCLK input case.

Since commit 7b11304 ("dma: mxs-dma: Report correct residue for cyclic DMA") the mxs dmaengine driver has support for residue reporting. So there is no need to specify the SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag anymore. This allows a finer grained resolution for the PCM pointer as well as avoids the race condition that can occur with the period counting that is used when the dmaengine driver does not support residue reporting.

A significant change in the subsystem level is the introduction of snd_soc_component, which will help more generic handling of SoC and off-SoC components. Also, snd_BUG_ON() macro is enabled unconditionally now due to its misuses, so people might hit kernel warnings (it's a good thing for us). - compress-offload: support for capture by Charles Keepax - HD-audio: codec delay support by Dylan Reid - HD-audio: improvements/fixes in generic parser: better headphone mic and headset mic support, jack_modes hint consolidation, proper beep attach/detachment, generalized power filter controls by David Henningsson, et al - HD-audio: Improved management of HDMI codec pins/converters - HD-audio: Better pin/DAC assignment for VIA codecs - HD-audio: Haswell HDMI workarounds - HD-audio: ALC268 codec support, a few new quirks for Chromebooks - USB: regression fixes: USB-MIDI autopm fix, the recent ISO latency fix by Clemens Ladisch - USB: support for DSD formats by Daniel Mack - USB: A few UAC2 device endian/cock fixes by Eldad Zack - USB: quirks for Emu 192kHz support, Novation Twitch DJ controller, Yamaha THRxx devices - HDSPM: updates for TCO controls by Adrian Knoth - ASoC: Add a snd_soc_component object type for generic handling of SoC and off-SoC components by Kuninori Morimoto, - dmaengine: a large set of cleanups and conversions by Lars-Peter Clausen - ASoC DAPM: performance optimizations from Ryo Tsutsui - ASoC DAPM: support for mixer control sharing by Stephen Warren - ASoC: multiplatform ARM cleanups from Arnd Bergmann - ASoC: new codec drivers for AK5385 and TAS5086 from Daniel Mack" * tag 'sound-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (315 commits) ALSA: usb-audio: caiaq: fix endianness bug in snd_usb_caiaq_maschine_dispatch ALSA: asihpi: add format support check in snd_card_asihpi_capture_formats ALSA: pcm_format_to_bits strong-typed conversion ALSA: compress: fix the states to check for allowing read ALSA: hda - Move Thinkpad X220 to use auto parser ALSA: USB: adjust for changed 3.8 USB API ALSA: usb - Avoid unnecessary sample rate changes on USB 2.0 clock sources sound: oss/dmabuf: use dma_map_single ALSA: ali5451: use mdelay instead of large udelay constants ALSA: hda - Add the support for ALC286 codec ALSA: usb-audio: USB quirk for Yamaha THR10C ALSA: usb-audio: USB quirk for Yamaha THR5A ALSA: usb-audio: USB quirk for Yamaha THR10 ALSA: usb-audio: Fix autopm error during probing ALSA: snd-usb: try harder to find USB_DT_CS_ENDPOINT ALSA: sound kconfig typo ALSA: emu10k1: Fix dock firmware loading ASoC: ux500: forward declare msp_i2s_platform_data ASoC: davinci-mcasp: Add Support BCLK-to-LRCLK ratio for TDM modes ASoC: davinci-pcm, davinci-mcasp: Clean up active_serializers ...

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().
