Mark Brown	5fb4d38b19	mfd: Move WM831x to generic IRQ ... Replace the wm831x-local IRQ infrastructure with genirq, allowing access to the diagnostic infrastructure of genirq and allowing us to implement interrupt support for the GPIOs. The switchover is done within the wm831x specific IRQ API, further patches will convert the individual drivers to use genirq directly.

Mark Brown	7d4d0a3e73	mfd: Add WM831x interrupt support ... The WM831x includes an interrupt controller managing interrupts for the various functions on the chip. This patch adds support for the core interrupt block on the device. Ideally this would be supported by genirq, particularly for the GPIOs, but currently genirq is unable to cope with controllers on interrupt driven buses so we cut'n'paste the generic interface. Once genirq is able to cope chips like this it should be a case of filing the prefixes off the code and redoing wm831x-irq.c to move over.
