2017-01-18ASoC: arizona: Propagate errors from arizona_spk_initCharles Keepax1-1/+5
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>
2016-11-30ASoC: arizona: Use component pin control functionsRichard Fitzgerald1-1/+2
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.

2016-11-10ASoC: arizona: Call arizona_init_notifiers for all CODECsCharles Keepax1-0/+1
The call to arizona_init_notifiers was only added for CODECs that are generating voice trigger events, however, this is somewhat annoying for machine drivers that might be used with multiple CODECs as they need to conditionally register for the notifier, depending on the CODEC being attached. As the cost of initialising the notifier is so minimal, and we may well add other events in the future that apply to more CODECs, simply do this for all Arizona CODECs.

2016-10-26ASoC: arizona: Move request of speaker IRQs into bus probeCharles Keepax1-5/+21

Check for snd_soc_codec_driver structures that are only passed to snd_soc_register_codec or memcpy (2nd arg), for which the corresponding parameters are declared const.

2016-08-08ASoC: codec duplicated callback function goes to component on wm8997Kuninori Morimoto1-6/+8
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.

2016-02-05ASoC: arizona: Add support for SNDRV_PCM_RATE_KNOTCharles Keepax1-1/+1
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.

2015-07-07ASoC: arizona: Implement stability check for LHPF coefficientsCharles Keepax1-4/+4

2015-07-07ASoC: arizona: Implement stability check for EQ coefficientsCharles Keepax1-8/+4
Specifying unstable coefficients for the EQ can have a severe impact on the audio. This patchs adds a stability check on the coefficients written to the EQ, for this it is necessary to merge the mode control and the coefficients as some coefficients may only be unstable with a certain mode setting so it is ideal if these are always updated in sync.

2015-06-02ASoC: arizona: Export functions to control subsystem DVFSRichard Fitzgerald1-3/+8
The WM5102 and WM8997 codecs have an internal dynamic clock booster. When this booster is active, the DCVDD voltage must be increased. If all the currently active audio paths can run with the root SYSCLK we can disable the booster, allowing us to turn down DCVDD voltage to save power. Previously this was being done by having the booster enable bit set as a side-effect of the LDO1 regulator driver, which is unexpected behaviour of a regulator and not compatible with using an external regulator. [Originally this was documented as a feature of the internal LDO -- broonie] This patch exports functions to handle the booster enable and DCVDD voltage, with each relevant subsystem flagging whether it can currently run without the booster. Note that these subsystems are stateless and none of them are nestable, so there's no need for reference counting, we only need a simple boolean for each subsystem of whether their current condition could require the booster or will allow us to turn the codec down to lower operating power.
