2013-02-14mfd: arizona: Disable interrupts during resumeMark Brown
Runtime power management does not function during system suspend but the Arizona devices need to use runtime power management to power up the device in order to handle interrupts. Try to avoid interrupts firing during resume by disabling the primary IRQ before interrupts are reenabled on resume and only reenabling it again during main resume. The goal is to avoid issues in the situation where an interrupt is asserted during resume (eg, due to it being the wake source) and the interrupt handling gets scheduled prior to the device being able to handle runtime PM.

2013-02-12mfd: db8500-prcmu: update resource passingLinus Walleij
When trying to get rid of the cross-includes of <mach/id.h> from different drivers, so we can localize ASIC/CPU detection to the mach-ux500 folder, we run into the way the PRCMU handles base addresses and firmware detection. This patch updates the firmware version detection to pass the required information as platform data instead of relying on cpu_is_* macros. Now the PRCMU base address, the secondary TCDM area, the TCPM area and the IRQ are passed as resources instead of being grabbed from <mach/*> files. Incidentally this also removes part of the reliance on <mach/irqs.h>. Further it updates the firmware version detection, since the location of the firmware ID bytes in the designated memory are is now passed from the platform data instead. There is no reason not to include the nice split-off of a struct to hold the firmware information and a separate function to populate it. The patch actually rids the need to use the external db8500_prcmu_early_init call at all, but I'm keepin back that removal as I don't want the patch to be too big.

2013-02-08mfd: ab8500: provide a irq_set_type() functionLee Jones
In the AB8500 IRQ mask and unmask functions, we rely on testing for IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to physically mask and unmask the correct interrupt lines. In order for us to do that, the trigger needs to be set in the associated flags. However, unless a irq_set_type() function pointer is passed when registering the IRQ chip, the IRQ subsystem will refuse to do it. For that reason, we're providing one.

2013-02-08mfd: ab8500: actually handle the AB8500 GPIO IRQs correctlyLinus Walleij
The patch: "mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly" altered the AB8500 IRQ mask/unmask functions such that they would handle masking on/off the falling edge IRQ if this was requested by the consumer. However the bit mask for hwirqs 43 and 44 was shifting the bit mask incorrectly, resulting in the wrong IRQ being mased/unmasked. Further while the patch would mask/unmask the correct line, when the interrupt actually came in, it would still be treated as a valid hwirq. The offsetting applied when masking/unmasking was not applied when handling the IRQ, i.e. the falling edge lines were not routed back to the rising edge lines. This fixes both cases. The end result has been tested with the SIM detect IRQ, GPIO12, hwirq 46 and 62.

2013-02-08mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctlyLee Jones
In an upcoming patch, the gpio-ab8500 driver will relinquish all IRQ handling capability and pass it back into the AB8500 core driver. This will aid in reducing massive code duplication within the kernel. Also, most of the functionality is already in the AB8500 core driver, as the GPIO IRQs are actually sandwiched between lots of other IRQs which the core driver already handles. All we're doing here is providing the core driver with knowledge that each GPIO has two IRQs assigned to it; one for rising and a separate one for falling.
