The hardware doesn't support affinity on individual error interrupts.

2014-04-18fsl_pme: disable interrupts in suspendJeffrey Ladouceur
In order to enter deepsleep the pme device must clear all pending interrupts. Setting the interrupt inhibit register accomplishes this. On wakeup this register is restored by the original backed up value.

2014-04-09fsl_pme: Support for power managementJeffrey Ladouceur
Change the pme error interrupt handler to be per-CPU to avoid a warning ("Cannot set affinity for irq") when entering suspend-to-ram state. Added IRQF_PERCPU flag. While sending frames to the PME device, this device can return a serious error. Added logic to properly handle this scenario. If this happens while reading the pme database, upon resume the resulting database will not be restored. The size of the confidence table was incorrect for a specific version of pme.

2014-04-09fsl_pme: Add support for suspend and resume power management callbacksJeffrey Ladouceur
When power is removed from the pme device, all its internal state is lost. The suspend() function saves all necessary state in order to later resume the device. The resume() function "writes" back the previously saved state. The functionality is implemented as part of the pme ctrl plane device. The state the requires saving is CCSR registers and internal SRAM memory.
