Modern devices allow systems to enable and disable individual supplies on the device, allowing additional power saving by switching off regulators which power portions of the device which are not currently in use. Add a new SND_SOC_DAPM_REGULATOR_SUPPLY widget type factoring out the code for managing such widgets from individual drivers. The widget name will be used as the supply name when requesting the regulator from the regulator API.

Provide managed versions of regulator_get() and regulator_bulk_get(), saving code in error handling and cleanup paths by ensuring that that the regulators will be automatically unregistered when the device is unregistered.

When the hardware is configured with one or both of the IN4 inputs used for DC measurement (with no DC blocking capacitor connected) then we can improve power consumption slightly in idle modes by applying a register write sequence. Provide platform data to enable this, implemented using a regmap patch. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Merge tag 'regmap-patch-initial' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into for-3.4 regmap: Inital export of the patching implementation An initial export of the regmap register patch implementation, mostly for integration into ASoC so it can be used by drivers there which have conflicting updates already.

Device manufacturers frequently provide register sequences, usually not fully documented, to be run at startup in order to provide better defaults for devices (for example, improving performance in the light of silicon evaluation). Support such updates by allowing drivers to register update sets with the core. These updates will be written to the device immediately and will also be rewritten when the cache is synced. The assumption is that the reason for resyncing the cache will always be that the device has been powered off. If this turns out to not be the case then a separate operation can be provided. Currently the implementation only allows a single set of updates to be specified for a device, this could be extended in future. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

If a driver is using regmap directly ensure that we're coherent with non-ASoC register updates by using the regmap API directly to do our read/modify/write cycles. This will bypass the ASoC cache but drivers using regmap directly should not be using the ASoC cache. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
