* ASoC: Add WM8912 DAC supportMark Brown2010-02-041-18/+72
| | | | | | | | | The WM8912 is a DAC only device register compatible with the WM8904 CODEC with ADC portions omitted. Support it within the WM8904 driver based on the configured I2C device name.

* ASoC: Optimise WM8904 output stage power controlMark Brown2010-02-041-7/+27
| | | | | | | | | | Handle the output PGAs as part of the output powerup since they can never be powered separately and reorder things so that we remove the output shorts after both line and headphone outputs have been brought up, minimising the opportunity for any issues.

* ASoC: Add support for BIAS_OFF when idle to WM8904Mark Brown2010-02-041-13/+39
| | | | | | | | | | | | | | As well as disabling the biases of the CODEC the drop into BIAS_OFF will also disable all the regulators powering the CODEC, allowing even greater power savings on appropriately configured systems. Since the regulator API does not currently provide notification when regulators are disabled we assume that this always happens when we stop using the regulators. Once 2.6.34 is merged this code can be optimised to only sync the cache when power was actually removed.

* ASoC: Initial WM8904 CODEC driverMark Brown2009-12-041-0/+2538
The WM8904 is a high performance ultra-low power stereo CODEC optimised for portable audio applications, with features including a class W amplifier, FLL with free running mode, Mobile ReTune and ground referenced headphone and line outputs. Support for some features, most particularly the digital microphone interface, is not yet present.
