2011-10-22ASoC: wm8996: Fix wrong mask for setting WM8996_AIF_CLOCKING_2Axel Lin

2011-10-20ASoC: wm8996: Use SND_SOC_DAPM_AIF_OUT for AIF2 CaptureAxel Lin

2011-10-03ASoC: Remove needless codec->dapm.bias_level assignment to SND_SOC_BIAS_OFFAxel Lin
This assignment is done by the snd_soc_register_codec so there is no need to redo it in probe function of a codec driver. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-09-20ASoC: Refcount WM8996 bandgap from FLL tooMark Brown
For digital only paths we need to make sure the bandgap is enabled prior to starting the FLL which isn't tied into DAPM. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-09-20ASoC: Fix unused variable warning in WM8996Mark Brown

2011-09-19ASoC: Initial WM8996 headphone impedance measurement supportMark Brown
The WM8996 can measure the impedance of accessories connected to the headphone output. Implement initial support for this, measuring the left channel impedance when an accessory is detected and using this to distinguish between a line load and a headphone load.

2011-09-19ASoC: WM8996 only needs bandgap for analogue functionalityMark Brown
Rather than managing the bandgap in the bias level control use a supply widget as we only actually need to enable it for analogue paths, not fully digital ones. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-09-16ASoC: Fix WM8996 DC servo operation without IRQMark Brown
We need to count the timeout down. Reported-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-09-14ASoC: Correct channel numbers for WM8996 AIF2Mark Brown
The AIF1 channels are numbered from zero than one; do the same thing for AIF2 too. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-09-14ASoC: Disable WM8996 CPVDD supply when not in useMark Brown
The WM8996 only requires CPVDD when the charge pump is active so control it separately to the other supplies, only enabling it when the charge pump is active. This will result in a small power saving on systems which are able to provide independent software control of the supply.

2011-09-05ASoC: Check that WM8996 FLL started even if we don't have the IRQMark Brown
We can directly read the FLL lock status on WM8996 so even if we don't have an interrupt wired up we can still verify that the FLL started successfully. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

I can count. Honest. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

2011-08-22ASoC: Clear completions from late WM8996 FLL lock IRQsMark Brown
In case we have a pending completion, for example due to a problem with the input clock which got corrected after we timed out. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-08-22ASoC: Optimise WM8996 no interrupt pathMark Brown
This occurs frequently if we are in edge triggered mode as we must poll the interrupt status register until we get no more interrupts so it's worth the effort - it means we skip writing null acknowledgements to the chip.

2011-08-22ASoC: Automatically manage WM8996 MICBIAS regulating modeMark Brown
For non-audio uses like accessory detection we can use a lower quality, unregulated microphone bias, saving a little power. As the hardware can manually enable and disable the biases we can select regulating mode automatically with supply widgets connected to the biases.

2011-08-22ASoC: Fix configuration of WM8996 input enablesMark Brown
There's no need for separate widgets for the enables (as the map already shows). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-08-22ASoC: WM8996 record paths need AIFCLKMark Brown
Make AIFCLK supply the record paths otherwise record will not work unless there is a simultaneous playback. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2011-08-08ASoC: Acknowledge WM8996 interrupts before acting on themMark Brown
This closes the small race between a status being read in response to an interrupt and clearing the interrupt, meaning that if the status changes between those periods we might not get a reassertion of the interrupt. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-08-08ASoC: Rename WM8915 to WM8996Mark Brown
For marketing reasons the part will be called WM8996. In order to avoid user confusion rename the driver to reflect this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Acked-by: Liam Girdwood <lrg@ti.com>
