Ensure that the audio subsystem is powered down cleanly when the system shuts down by providing a shutdown operation. This ensures that all the components have been returned to an off state cleanly which should avoid audio issues from partially charged capacitors or noise on digital inputs if the system is restarted quickly.

Event for voice sidetone was being interpreted as an analog HiFi bypass event because VSTPGA register offset is less than ARXR2_APGA_CTL offset. Reordering the register checks allows to handle voice digital bypass event properly.

Add basic support for integration with the regulator API to WM8580. Since the core cannot yet disable biases when the CODEC is idle we simply request and enable the regulators for the entire time the driver is active. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

This patch mostly follows commit 5998102b "ASoC: Refactor WM8731 device registration" to make UDA1380 use standard device instantiation. Similarly, the I2C device registration temporarily moves into the magician machine driver before it will find its final resting place in the board file. At the same time, platform specific configuration is moved to platform data and common power/reset GPIO handling moves into the codec driver.

Now that ASoC subdevices can be regular devices they can have normal suspend and resume calls from their buses. However, suspending them individually is not desirable since this can lead to problems such as pops and clicks from devices being suspended with their signals being amplified or clocks being stopped suddenly. This will be resolved by having the normal device model suspend and resume calls call into ASoC which will suspend the entire card while any of its components are suspended. At present this is not yet implemented but in order to aid the transition of drivers to the standard device model this patch adds API calls for the notifications.

Handle gain ramping for PGAs so we can coalesce their power updates too. This is not ideal since we can't cope properly with gain ramping for stereo paths but that was the case without coalescing and gain ramping is relatively infrequently used so the effects are limited.

Reduce the number of register writes we need to set the power state for a CODEC by coalescing updates to widgets with the same sequence order and same register into a single write. This can be a noticable performance improvement with slow or heavily contended control buses, such as I2C controllers with a low clock frequency, and is particularly noticable when resuming. It can also reduce the noticability of and pops and clicks by ensuring that left and right channels are powered simultaneously if they are in the same register. Currently widgets that have events are not coalesced, including PGAs which may use the volume ramping control. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

In the past the DAPM power sequencing was done by iterating over the list of widgets once for each widget type and powering widgets of that type. Instead of doing that do the sorting at the time we insert the widgets into the lists of widgets to apply power changes to. This reduces the amount of computation required for seqencing still further, though the costs are generally dwarfed by the costs of the register writes implementing them.

In case the initalization of an soc_device failed, there is no codec associated with it. soc_suspend() will still dereference the pointer and cause an Ooops when entering the sleep mode. This happens on our board with a multi-target kernel image when booted on a machine without audio circuits. This patch makes the code bail out very early in this special case.
