* mfd: Use request_threaded_irq for twl4030-irq instead of irq_set_chained_handlerNeilBrown2011-12-20
| | | | | | | | | | | | | | | | irq_set_chained_handler sets 'desc->handle_irq'. However this irq is called by handle_nested_irq from handle_twl4030_pih, and that uses action->thread_fn. So the handled set with irq_set_chained_handler is never called. So change to use request_threaded_irq instead - that sets the correct field. Tested on GTA04 Phoenux.

* mfd: Base interrupt for twl4030-irq must be one-shotNeilBrown2011-12-20
| | | | | | | | | | | | As the interrupt source is only cleared by the threaded interrupt service routine, we need to make the base interrupt IRQF_ONESHOT. Without this, the first interrupt from the TWL4030 cause the CPU to enter an infinite loop trying to handle to interrupt but never clearing it.

Although the irq_desc and lock are different, LOCKDEP treats these as equivalent, presumably due to problems that can be incurred when locking more than one irq_desc, so best to avoid this.

| * mfd: Add Intel MSIC driverMika Westerberg2011-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Intel MSIC chip found on Intel Medfield platforms. This chip embeds several subdevices: audio, ADC, GPIO, power button, etc. The driver creates platform device for each subdevice. We also provide an MSIC register access API which should replace the more generic SCU IPC interface currently used. Existing drivers can choose whether they convert to this new API or stick with the SCU IPC interface.

| * mfd: Simulate active high IRQs with wm831xMark Brown2011-10-24
| | | | | | | | | | | | | | | | | | | | | | In order to ease system integration provide a simulation of active high IRQs on the GPIOs by polling the GPIO status when an IRQ is generated. This isn't ideal on several fronts and will miss initially active IRQs in the current implementation but it should work well for most cases.
