2011-12-13mfd: Convert wm8994 to use generic regmap irq_chipMark Brown
Factor out the irq_chip implementation, substantially reducing the code size for the driver. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Mark WM1811 GPIO6 register volatile for later revisionsMark Brown
For later chip revisions the WM1811 GPIO6 register is always volatile so store the device revision when initialising the driver and then check at runtime if we're running on a newer device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Add missing mutex.h inclusion to WM8994 core.hMark Brown
struct wm8994 includes a mutex so we need to include mutex.h before we declare it. All current users rely on this being done implicitly. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Constify WM8994 regulator_init_dataMark Brown
The driver has no need to modify the regulator_init_data so declare it const to allow machine code to do so. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Enable register cache for wm8994 devicesMark Brown
As part of this we provide information about the registers that exist in the device to the regmap core, drop the small amount of cache that the core had been using and let regmap do the sync. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Define some additional wm8994 registersMark Brown
Add a bunch of definitions for wm8994 registers that are not currently used by software. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-13mfd: Disable more pulls on WM8994Mark Brown
Disable more pulls by default on WM8994 for a small current saving. Since some designs do leave SPKMODE floating provide platform data to allow that to be left enabled. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>
2011-12-01ASoC: Add platform data for WM8958/WM1811 microphone detection ratesMark Brown
Allow systems to override the default microphone detection rates using platform data in case the settings are not suitable (eg, due to an unusually noisy jack). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-12-01ASoC: Implement support for WM1811A jack detectionMark Brown
The WM1811A features an advanced low power accessory detection subsystem which allows the device to be maintained in a very low power state while the system is idle without sacrificing any accessory detection features. Implement software support for this, automatically managing the power configuration of the device depending on the detected accessory. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-12-01ASoC: Allow more WM8958/WM1811 button levels with default handlerMark Brown
The WM8958 and WM1811 support detecting a range of buttons. Allow the user to provide platform data enabling more of these levels without having to write a custom detection handler. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-11-04ASoC: Ensure we get an impedence reported for WM8958 jack detectMark Brown
Occasionally we may see an accessory reported before we have a stable impedance for the accessory. If this happens then reread the status in order to ensure that the handler can take the appropriate action for the status change. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-10-24mfd: Allow WM8994 LDO enable pulls to be disabledMark Brown
In systems where the LDO enables are always driven (for example, being connected to an always on supply rail or a GPIO which is driven by the CPU even in suspend) then we can disable the pull downs on the LDO for a small power savings.

2011-10-04ASoC: Add WM1811 supportMark Brown
The WM1811 is mostly register compatible with the WM8994 and WM8958, providing a high performance audio hub CODEC in a small form factor suitable for ultra compact system designs. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-09-06mfd: Fix value of WM8994_CONFIGURE_GPIOMark Brown
This needs to be an out of band value for the register and on this device registers are 16 bit so we must shift left one to the 17th bit. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@kernel.org Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2011-03-02mfd: Don't suspend WM8994 if the CODEC is not suspendedMark Brown
ASoC supports keeping the audio subsysetm active over suspend in order to support use cases such as audio passthrough from a cellular modem with the main CPU suspended. Ensure that we don't power down the CODEC when this is happening by checking to see if VMID is up and skipping suspend and resume when it is. If the CODEC has suspended then it'll turn VMID off before the core suspend() gets called.

2011-02-22ASoC: Support configuration of WM8958 microphone bias analogue parametersMark Brown
The WM8958 has a different microphone bias architecture to WM8994 so needs different configuration to WM8994. Support this in platform data. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2011-02-22ASoC: Support WM8958 direct microphone detection IRQMark Brown

2010-12-01ASoC: Allow user-specified WM8958 multiband compressor configurationsMark Brown
The paramters of the WM8958 multiband compressor can be tuned by the user for their system using a graphical configuration tool on the host. Allow the user to specify a set of such paramters in platform data and select between them at runtime.

2010-11-27ASoC: Add WM8958 microphone detection supportMark Brown
The WM8958 contains an advanced accessory detection feature which allows detection of up to seven different impedence levels on the microphone bias output, including detection of video outputs. Since some of the more involved accessory interfaces may involve noticable interactions with external components a simple detection scheme is provided by default with the option to provide custom handling of accessory detect.

2010-11-27ASoC: Add WM8958 Multi-band compressor supportMark Brown
The WM8958 features a multi-band compressor which can be enabled on any of the AIF inputs. The MBC allows different gains to be applied to differnt audio bands, providing an improvement in perceived loudness of the signal by avoiding overdriving the output transducers. This patch enables support for the MBC. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>
2010-11-27ASoC: Implement support for enhanced AIF3 on WM8958Mark Brown

2010-11-26mfd: Add initial WM8958 supportMark Brown
The WM8958 is a derivative of the WM8994 which is register compatible with the addition of some extra features, mostly in the CODEC side. The major change visible at the MFD level is that rather than a single DBVDD supply we now have three separate DBVDDs so we must request and enable a different set of supplies.

2010-04-05mfd: Add WM8994 interrupt controller supportMark Brown
The WM8994 has an interrupt controller which supports interrupts for both CODEC and GPIO portions of the chip. Support this using genirq, while allowing for systems that do not have an interrupt hooked up. Wrapper functions are provided for the IRQ request and free to simplify the code in consumer drivers when handling cases where IRQs are not set up.

2010-03-07mfd: Add initial WM8994 supportMark Brown
The WM8994 is a highly integrated ultra low power audio hub CODEC. Since it includes on-board regulators and GPIOs it is represented as a multi-function device, though the overwhelming majority of the functionality is provided by the ASoC CODEC driver.
