2010-03-07mfd: Convert WM8350 to genirqMark Brown
This gives us use of the diagnostic facilities genirq provides and will allow implementation of interrupt support for the WM8350 GPIOs. Stub functions are provided to ease the transition of the individual drivers, probably after additional work to pass the IRQ numbers via the struct devices.

2010-03-07mfd: Add a data argument to the WM8350 IRQ free functionMark Brown
To better match genirq. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-01-18mfd: WM8350 off by one bugDan Carpenter
If irq == WM8350_NUM_IRQ that would put us past the end of the array. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Mask and unmask wm8350 IRQs on request and freeMark Brown
Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.

2009-12-13mfd: Convert wm8350 IRQ handlers to irq_handler_tMark Brown
This is done as simple code transformation, the semantics of the IRQ API provided by the core are are still very different to those of genirq (mainly with regard to masking). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-12-13mfd: Convert WM835x IRQ handling to use a data tableMark Brown
Rather than open coding individual IRQs in each function which manipulates them store data for IRQs in a table which is then referenced in the users. This is a substantial code shrink and should be a performance win in cases where only a single IRQ goes off at once since instead of reading four of the second level IRQ registers for each interrupt we read only the sub-registers which have had an interrupt flagged.

2009-12-13mfd: Split wm8350 IRQ code into a separate fileMark Brown
In preparation for refactoring - it's over 700 lines of well-isolated code and having it in a file by itself makes things more managable. While we're at it make sure that we clean up the IRQ if we fail after acquiring it on init.
