2010-02-04ASoC: Disable WM8993 regulators when turning bias offMark Brown
While the regulators are disabled we cache all register writes. Currently we assume that the regulator disable actually takes effect, after the merge with the regulator tree in 2.6.34 the regulator API will be able to notify us if the power is actually removed (due to constraints or regulator sharing it may not be).

2010-02-04ASoC: Initial WM8993 regulator API hookupMark Brown
At the minute the regulators are simply enabled for the entire lifetime of the device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-02-04ASoC: Convert WM8993 to use shared cache I/O codeMark Brown
Saves a little bit of code duplication. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2010-02-01ASoC: Improved wm_hubs headphone handlingMark Brown
Perform DC servo offset calibration using a series update sequence rather than startup update sequence, tuning the configuration of the WM8993 DC servo to make best use of this. Also introduce currently unused data allowing us to correct for any systematic errors in the DC servo calibration results and an alternative startup path for the headphone output which performs better with some chip revisions. The alternative setup sequence is enabled for WM8993. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2009-11-12ASoC: Remove redundant snd_soc_dapm_new_widgets() callsMark Brown
The DAPM widgets are now insntantiated by the core when creating the card so there is no need for the individual CODEC drivers to do so. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-11-03ASoC: Factor out snd_soc_init_card()Mark Brown
snd_soc_init_card() is always called as the last part of the CODEC probe function so we can factor it out into the core card setup rather than have each CODEC replicate the code to do the initialiastation. This will be required to support multiple CODECs per card. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-09-30ASoC: Factor out analogue platform data from WM8993Mark Brown
This is also shared with newer CODECs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-09-05ASoC: Add source argument to PLL configurationMark Brown
More and more devices feature PLLs and FLLs with the ability to select between multiple input clocks. In order to better support these devices a new argument, source, has been added to the set_pll() configuration API. Using set_clkdiv() is often difficult due to the need to stop the PLL/FLL before any reconfiguration can be done. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-08-18ASoC: WM8993 digital mixing supportMark Brown
The WM8993 provides digital sidetone paths and also allows each channel on the audio interface to be routed separtately to the DACs and ADCs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-17ASoC: Implement TDM configuration for WM8993Mark Brown
Note that the number of slots used internally is specified in terms of stereo slots while the external API works with mono slots. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-17ASoC: Fix WM8993 MCLK configuration for high frequency MCLKsMark Brown
When used without the PLL we were accidentally clearing the MCLK/2 divider, resulting in a double rate SYSCLK when the divider should have been used. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-08-13ASoC: Factor out shared code from WM8993Mark Brown
The WM8993 analogue control is shared with other devices in the same product line. Since this is a very substantial proportion of the driver move the definitions of these controls into a new wm_hubs module which allows them to be shared between the two.
