* mfd: wm8994: Remove unused irq_lockMark Brown2013-10-231-2/+0
| | | | | | | Since the conversion to regmap-irq irq_lock has been unused. Signed-off-by: Mark Brown <broonie@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: wm8994: Inline register I/O functionsMark Brown2013-10-231-9/+36
| | | | | | | | | Since the register I/O functions are all simple wrappers for the regmap equivalents inline them to provide a small code size saving and an example of good practice. Signed-off-by: Mark Brown <broonie@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: wm8994: Emulate level triggered interrupts if requiredMark Brown2013-06-111-0/+2
| | | | | | | | | The interrupt controller on the wm8994 series of devices requires a level triggered parent. If one is not available but a GPIO is available for the interrupt then emulate.

* mfd: wm8994: Store platform data in deviceMark Brown2012-11-231-0/+4
| | | | | | | | | This is better style as platform data is supposed to be discardable after init (though hotplug usually prevents this) and will ease implementation of device tree property bindings.

* | mfd: wm8994: Update to fully use irq_domainMark Brown2012-05-151-6/+6
|/ | | | | | | | | | Take advantage of the new regmap irq_domain support to dynamically allocate interrupts, using regmap_irq_get_virq() rather than irq_base to look up the interrupts. This means that most users should not need to specify an irq_base at all. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | 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.

* mfd: Don't suspend WM8994 if the CODEC is not suspendedMark Brown2011-03-021-0/+1
| | | | | | | | | | | | 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.

* mfd: Add initial WM8958 supportMark Brown2010-11-261-0/+8
| | | | | | | | | | | | 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.

* mfd: Add WM8994 interrupt controller supportMark Brown2010-04-051-1/+52
| | | | | | | | | | | | | 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.

* mfd: Add initial WM8994 supportMark Brown2010-03-071-0/+54
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.
