* ASoC: Fix backport of WM8994 thermal warningMark Brown2011-08-17
| | | | | Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
* ASoC: Implement WM8994 thermal warning and shutdown interrupt supportMark Brown2011-08-16
| | | | | | | ALSA doesn't really have good mechanisms for dealing with these so we just log them - the hardware already has automatic shutdown support. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* ASoC: Disable pulls on WM8994 AIF2 when starting itMark Brown2011-08-15
| | | | | | | | | | Pull control is availalbe for WM8994 AIF2, generally disabled as part of the GPIO configuration in order to save power after system startup. As on newer devices in the series there is no GPIO functionality on these pins this will happen less naturally so have the driver disable the pulls as the AIF is probed.

* ASoC: Disable WM8994 VMID for digital only pathsMark Brown2011-08-14
| | | | | | | | | | | On WM8994 class devices only the analogue portions of the CODEC require VMID so when running digital only paths we can leave VMID disabled. On some earlier devices the FLL uses VMID so we don't use DAPM reference counting alone, we maintain an internal reference count which is also enabled and disabled by the FLL startup.

* | ASoC: Implement new DC servo readback mode for late WM8994 revisionsMark Brown2011-08-01
|/ | | | | | | | | Later WM8994 devices implement a new DC servo readback mode with the register used to access the offset moved to register 0x59. Implement support for this and enable it on the appropriate devices. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

| * ASoC: Correct WM8994 MICBIAS supply widget hookupMark Brown2011-07-17
| | | | | | | | | | | | | | | | | | | | | | | | The WM8994 and WM8958 series of devices have two MICBIAS supplies rather than one, the current widget actually manages the microphone detection control register bit (which is managed separately by the relevant API). Fix this, hooking the relevant supplies up to the MICBIAS1 and MICBIAS2 widgets. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@kernel.org
* | ASoC: Reduce power consumption for idle DAIs in WM8994Mark Brown2011-07-17
| | | | | | | | | | | | | | | | If DAIs are idle but their clocks are in use for some reason (eg, as SYSCLK or for accessory detect) then set the clock dividers to the maximum to reduce slightly the power consumption of the unclocked circuits.

* | ASoC: Handle failed WM8994 FLL lock waitsMark Brown2011-07-17

| | | | | | | | | | | | | Commit fafd217 ("ASoC: Store a list of widgets in a DAPM mux/mixer kcontrol") changed the control private data type that is passed to snd_soc_cnew when creating dapm mixer and mux controls. Commit did not update a few codec drivers that are using their own put callbacks and thus are accessing a wrong data type.

* ASoC: Disable WM8994/58 microphone detection over suspendMark Brown2011-05-11
| | | | | | | | | | It will be non-functional with the basises and clocks off anyway, if the system needs microphone detection enabled over suspend then it should be causing the CODEC to ignore suspend using the APIs for that to prevent the biases being disabled.

* | ASoC: Simplify default WM8958 jack detection codeMark Brown2011-02-22
| | | | | | | | | | | | | | | | | | | | | | | | The default WM8958 jack detection handler implements a full set of buttons and also support for video detection. Support for multi-button jacks is fairly system specific and will usually require some tuning for headsets so simplify the implementation to only report a simple short to ground button, leaving multi-button headsets to be handled by system specific code.
