2016-12-15ASoC: atmel: tse850: rely on the ssc to register as a cpu dai by itselfPeter Rosin
This breaks devicetree compatibility, but in this case that is ok. All affected units are either on my desk, or running an even older version of the driver that is not compatible with the upstreamed version anyway (and when these other units are eventually updated, they will get a fresh dtb as well, so that is not a significant problem either). All of that is of course assuming that noone else has managed to build something that can use this driver, but that seems extremely improbable.

When this driver masters BCLK and/or LRCLK, and noone has stated differently, assume that all the bits of a frame are used.

2015-04-27ASoC: dmaengine_pcm: Make FLAG_NO_RESIDUE internalLars-Peter Clausen
Whether residue can be reported or not is not a property of the audio controller but of the DMA controller. The FLAG_NO_RESIDUE was initially added when the DMAengine framework had no support for describing the residue reporting capabilities of the controller. Support for this was added quite a while ago and recently the DMAengine framework started to complain if a driver does not describe its capabilities and a lot of patches have been merged that add support for this where it was missing. So it should be safe to assume that driver on actively used platforms properly implement the DMA capabilities API. This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio controller drivers to manually set the flag. If a DMA driver against expectations does not support reporting its capabilities for now the generic DMAengine PCM driver will now emit a warning and simply assume that residue reporting is not supported. In the future this might be changed to aborting with an error. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

This patch adds the missing route and then sets the fully_routed flag for the card. This allows to remove all the manual calls to snd_soc_dapm_nc_pin().

2015-02-10ASoC: atmel_ssc_dai: Allow more ratesPeter Rosin
When the SSC acts as BCK master, use a ratnum rule to limit the rate instead of only doing the standard rates. When the SSC acts as BCK slave, allow any BCK frequency up to the SSC master clock, divided by either of 2, 3 or 6. Put a cap at 384kHz. Who's /ever/ going to need more than that? The divider of 2, 3 or 6 is selected based on the Serial Clock Ratio Considerations section from the SSC documentation: The Transmitter and the Receiver can be programmed to operate with the clock signals provided on either the TK or RK pins. This allows the SSC to support many slave-mode data transfers. In this case, the maximum clock speed allowed on the RK pin is: - Peripheral clock divided by 2 if Receiver Frame Synchro is input - Peripheral clock divided by 3 if Receiver Frame Synchro is output In addition, the maximum clock speed allowed on the TK pin is: - Peripheral clock divided by 6 if Transmit Frame Synchro is input - Peripheral clock divided by 2 if Transmit Frame Synchro is output Signed-off-by: Peter Rosin <peda@axentia.se> Acked-by: Bo Shen <voice.shen@atmel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
