2017-01-18ASoC: arizona: Propagate errors from arizona_spk_initCharles Keepax
arizona_spk_init uses snd_soc_dapm_new_control which since commit 37e1df8c95e2 ("ASoC: dapm: handle probe deferrals") will occasionally request a probe deferral. Which means we should propagate the error out of our driver from it. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-01-06ASoC: wm_adsp: Add mechanism to preload firmware on a coreCharles Keepax
As requirements to bring up audio paths are continuous getting tighter and the DSP download to most ADSP devices happens over an external bus it can become an important factor in the path bring up time. As such sometimes it is a reasonable trade off to download the firmware ahead of when it will be required and take a small hit on power consumption for keeping the core powered up. This "preloading" adds an additional control for each DSP core "DSPx Preload Switch" that when set to true will power up the DSP core and download the firmware currently selected in the "DSPx Firmware" control. Whilst the core is preloaded the current firmware can not be changed and the CODEC will be kept powered up and SYSCLK held on. Although future improvements may allow the SYSCLK to be powered down as well because the hardware only requires SYSCLK whilst the download is actually taking place, but this is not covered in this series.

2016-11-30ASoC: arizona: Use component pin control functionsRichard Fitzgerald
We need to modify the state of some of our own pins and are currently not taking account that the pin name may have a name_prefix applied to it. Replace the snd_soc_dapm_x_pin functions with the equivalent snd_soc_component_x_pin functions so that any name_prefix will be handled automatically.

2016-10-26ASoC: arizona: Access driver data through platform from compressed opsCharles Keepax
As the compressed ops run on the platform side of things we should really access the driver data through the platform pointer rather than the CODEC pointer. As the compressed DAIs in our systems always connect our CODEC to our platform this has never been an issue, but should still be corrected. Additionally it clears the way for future core refactoring work.

2016-10-24ASoC: arizona: Add gating for clock when used for direct MCLKCharles Keepax
Whilst ultimately we would like to move all the clocking over to the clock framework, as an intermediate step to get people going for now gating the source clocks for SYSCLK/ASYNCCLK when they are configured to come directly from an MCLK pin.

2016-09-24ASoC: arizona: Attach SYSCLK to DSP preloadersCharles Keepax
Currently SYSCLK is attached to every compressed DAI as this follows the pattern of attaching clocks to the chips inputs and outputs, however, it is really the DSP that requires the clock here. As firmware download can be a significant part of the path startup time for these devices occasionally it would be desirable to download the firmware in advance of the path being brought up. To help facilitate this early firmware loading this patch attaches the SYSCLK to the DSP preloader widget. This also saves us adding a new route to SYSCLK every time a new compressed DAI is created.

2016-08-11ASoC: arizona: Connect ASRCs to both clock domainsCharles Keepax
The two clock domains are enabled based on each input and output of the chip being connected to its respective clock domain. The ASRC however can bridge the two domains and as such can function as an input/output to either domain. The hardware also requires that both clocks are enabled before the ASRC is. Ensure these constraints by linking the ASRCs to both SYSCLK and ASYNCCLK. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-08-08ASoC: codec duplicated callback function goes to component on cs47l24Kuninori Morimoto
codec driver and component driver has duplicated callback functions, and codec side functions are just copied to component side when register timing. This was quick-hack, but no longer needed.

2016-05-31ASoC: arizona: Add data structure for voice trigger notifierCharles Keepax
64-bit builds would generate a warning when we passed the core number as a pointer through the notifier data: sound/soc/codecs/cs47l24.c:1091:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] (void *)i); Rather than just fix this up with more casting add a data structure that holds information for the notifier chain. This will make it easier to add additional information in the future as well.

2016-05-30ASoC: arizona: Add voice trigger output widgetCharles Keepax
In some situations the voice control firmware will by used to only provide a trigger notification event. In this case a compressed stream will not be opened by user-space, as such we need to provide a virtual output to power on the DSP in this use-case. This patch adds a virtual output 'DSP Voice Trigger' that can be used for this, and a switch that lets it be connected to the core when required.

2016-05-30ASoC: arizona: Tie SYSCLK to DRC signal activity widgetsCharles Keepax
The intent is for SYSCLK to be tied to all input and output widgets such that it turns on whenever the chip is in use. It is not tied to the DRC signal activity detect virtual outputs, whilst in practice this is unlikely to cause an issue (as an input will likely also be powered up) best to correct.

2016-02-05ASoC: arizona: Add support for SNDRV_PCM_RATE_KNOTCharles Keepax
The Arizona CODECs support several rates that do not have simple defines in ALSA. This patch adds support for SNDRV_PCM_RATE_KNOT so that users can open stream at these rates. As part of this we should always set constraints in arizona_startup, currently we only set the constraints if we already have a clock to limit rates to that family of sample rates. This patch updates this to set a constraint of all rates supported by the chip if we do not already know which family of rates to limit to. Finally we also reduce the list of rates supported in the constraints to only include those that are supported on current parts.

2016-01-29ASoC: wm_adsp: Move setting of DSP speed into CODEC specific codeCharles Keepax
The ADSP code should be agnostic of which CODEC it runs upon, currently there is only one remaining part of the implementation that doesn't follow this. When the DSP is booted on ADSP2 we read ARIZONA_SYSTEM_CLOCK_1 and use that to set the initial speed for the DSP clock. This patch factors that out into CODEC specific code, leaving the ADSP code entirely CODEC agnostic.
