The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

2010-05-28mfd: Ensure WM831x charger interrupts are acknowledged when suspendingMark Brown
The charger interrupts on the WM831x are unconditionally a wake source for the system. If the power driver is not able to monitor them (for example, due to the IRQ line not having been wired up on the system) then any charger interrupt will prevent the system suspending for any meaningful amount of time since nothing will ack them. Avoid this issue by manually acknowledging these interrupts when we suspend the WM831x core device if they are masked. If software is actually using the interrupts then they will be unmasked and this change will have no effect.
