2018-01-09ASoC: codecs: dmic: Make number of channels configurableMatthias Kaehlcke
The DMIC DAI driver specifies a number of 1 to 8 channels for each DAI. The actual number of mics can currently not be configured in the device tree or audio glue, but is derived from the min/max channels of the CPU and codec DAI. A typical CPU DAI has two or more channels, in consequence a single mic is treated as a stereo/multi channel device, even though only one channel carries audio data. This change adds the option to specify the number of used DMIC channels in the device tree. When specified this value overwrites the default channels_max value of 8 in the snd_soc_dai_driver struct of the codec.

2018-01-08ASoC: Intel: Fix nested/unnecessary Kconfig dependenciesPierre-Louis Bossart
This patch fixes a number of issues: 1. IOSF_MBI is only needed for byt-cr detection, which is only supported on Baytrail/Cherrytrail, move to HiFi2 config 2. SND_SOC_INTEL_SST should not select SND_SOC_INTEL_SST_ACPI, the latter config is only valid for Haswell/Baytrail legacy but not needed by Skylake 3. SND_SST_IPC_ACPI, used only by the atom/sst driver, should not select SND_SOC_INTEL_SST, none of the code under common/sst*.c is used This nesting of configs really makes no sense, it's easier to maintain if for each platform one can control what is strictly required.

The PCI-based platforms may be removed at some point since Medfield is not really supported by anyone, and with Edison now defunct support for Merrifield/Edison is to be determined.

Follow network example suggested by Linus, move Intel definitions in if/endif block and clarify in help text which options distro configurations should enable - everything except legacy Baytrail stuff and NOCODEC (test only) To avoid user confusion, machine drivers are handled with a submenu made dependent on this top-level selector. There should be no functionality change - except that sound capabilities are restored when using older configs without any user selection. Note that the SND_SOC_ACPI_INTEL_MATCH config is currently filtered out by the top-level selector. This will change in the near future to allow for this option to be selected by both SST and SOF drivers (simplification with submenu for machine drivers by Vinod Koul) Fixes: f6a118a800e3 ("ASoC: Intel: clarify Kconfig dependencies") Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-01-08ASoC: rockchip: i2s: fix playback after runtime resumeJohn Keeping
When restoring registers during runtime resume, we must not write to I2S_TXDR which is the transmit FIFO as this queues up a sample to be output and pushes all of the output channels down by one. This can be demonstrated with the speaker-test utility: for i in a b c; do speaker-test -c 2 -s 1; done which should play a test through the left speaker three times but if the I2S hardware starts runtime suspended the first sample will be played through the right speaker. Fix this by marking I2S_TXDR as volatile (which also requires marking it as readble, even though it technically isn't). This seems to be the most robust fix, the alternative of giving I2S_TXDR a default value is more fragile since it does not prevent regcache writing to the register in all circumstances. While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these are not writable so they do not suffer from the same problem as I2S_TXDR but reading from I2S_RXDR does suffer from a similar problem.
