* mfd: Implement tps65910 IRQ cleanupMark Brown2011-07-311-0/+1
| | | | | | | | | | The tps65910_irq_exit() cleanup function was generating a warning from sparse due to the lack of a prototype. This wasn't causing GCC warnings as the driver wasn't cleaning up its IRQs on exit at all so there was no use of an unprototyped function.

* mfd: Fix WM8994 IRQ register cache restore on resumeMark Brown2011-07-311-5/+11
| | | | | | | | | | | When the byte swap was factored out into the per-register I/O functions the register restore for the IRQ mask cache (which we use and store in CPU native format for the interrupt handler) was not updated to do a byte swap when it uses the bulk I/O. Fix this by writing the cache out one register at a time. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: Support multiple active WM831x AUXADC conversionsMark Brown2011-07-311-77/+177
| | | | | | | | | | | | | | | The WM831x AUXADC hardware can schedule multiple conversions at once, allowing higher performance when more than one source is in use as we can have the hardware start new conversions without having to wait for a register write. Take advantage of this in the interrupt driven case, maintaining a list of callers that are waiting for AUXADC conversions and completing them all simultaneously. The external interface of the AUXADC is not changed so there will be limited use of the feature immediately.

* mfd: Allocate wm835x irq descs dynamicallySascha Hauer2011-07-311-6/+12
| | | | | | | | | | | | | This allows boards to leave the irq_base field unitialized and prevents them having to reserve irqs in the platform. pdata can be optional for irq support now. Without pdata the driver allocates some free irq range. With pdata and irq_base > 0 the driver allocates exactly the specified irq. Without pdata the irq defaults to IRQF_TRIGGER_LOW.

* mfd: Read wm831x AUXADC conversion results before acknowledging interruptMark Brown2011-07-311-16/+31
| | | | | | | | | | Ensure that there's no possibility of loosing an AUXADC interrupt by reading the conversion result in the IRQ handler when using interrupts. Otherwise it's possible that under very heavy load a new conversion could be initiated before the acknowledgement for a previous interrupt has happened.

* mfd: Support dynamic allocation of IRQ range for wm831xMark Brown2011-07-311-5/+13

| | | | | | | | | | | | The WM831x IRQ set_type() operation is doing a direct register write when called but since set_type() is called with the bus lock held this isn't legal and could cause deadlocks in the IRQ core.

| * | | | hwmon: (lm90) Make SA56004 detection more robustJean Delvare2011-07-291-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a device ID register value of 0, the SA56004 detection is rather weak. Check several other register too to confirm the detection, as we do for other supported devices.

| * | | | hwmon: (lm90) Simplify handling of extended local temp registerJean Delvare2011-07-291-15/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The optional extended local temperature register can never have address 0, as this address is already used by another register. Thus we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on reg_local_ext being non-zero to determine if a given chip has this extension or not. This makes the code more simple.
