* mfd: Mask and unmask wm8350 IRQs on request and freeMark Brown2009-12-135-41/+9
| | | | | | | | | | | | | | | | | | | | 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.

* mfd: Convert wm8350 IRQ handlers to irq_handler_tMark Brown2009-12-136-34/+59
| | | | | | | | | 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).

* mfd: ezx-pcap: Don't pass pcap pointer as subdev drvdata.Antonio Ospite2009-12-131-1/+0
| | | | | | | | | | | Abusing subdev drvdata is not needed anymore, as all pcap subdevs are now retrieving the pcap pointer from their parent device. This change removes a leftover coming from early versions of ezx-pcap and its subdevs drivers.

* mfd: Allow configuration of VDCDC2 for tps65010Ben Dooks2009-12-132-0/+47
| | | | | | | | | | | | | | | Add function to allow the configuation fo the VDCDC2 register by external users, to allow changing of the standard and low-power running modes. This is needed, for example, for the Simtec IM2440D20 where we need to use the low-power mode to shutdown the LDO/DCDC that are not needed during suspend (saving substantial power) and the runtime use of the low-power mode to change VCore.

* mfd: Allow the board to choose any GPIO base for tps65010Ben Dooks2009-12-131-1/+1
| | | | | | | | | | | | | If the board does not care where the TPS turns up, then specifiying the value -1 to get gpiolib to dynamically allocate the base for the chip is valid. Change the test to look for != 0, so that any boards specifying zero will not end up with gpio that they didn't want.

* mfd: Fix more undefined twl4030-power resconfig value checksAmit Kucheria2009-12-131-2/+2
| | | | | | | | | | | | | | | | | Based on Aaro's previous fix, this needs to be fixed for the newly added remap_off and remap_sleep resources as well. The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true. The patch eliminates the following compiler warnings: drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource': drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to limited range of data type Signed-off-by: Amit Kucheria <amit.kucheria@verdurent.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | Currently the pcf50633-regulator driver data is set to the pcf50633 core structure, but the pcf50633-regulator remove handler assumes that it is set to the regulator device.

| | | | | | | | | | | | | Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link.

* mfd: Convert WM835x IRQ handling to use a data tableMark Brown2009-12-132-648/+387
| | | | | | | | | | | | | | 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.
