2013-02-14mfd: twl-core: Clean up module id lookup and definitionsPeter Ujfalusi2-85/+86
Use enums for all module definitions: twl_module_ids for common functionality among twl4030/twl6030 twl4030_module_ids for twl4030 specific ids twl6030_module_ids for twl6030 specific ids In this way the list can be managed easier when new functionality going to be implemented.

2013-02-14mfd: arizona: Disable interrupts during resumeMark Brown1-0/+26
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.

2013-02-08mfd: ab8500: provide a irq_set_type() functionLee Jones1-0/+6
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 Walleij1-3/+19
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 Jones1-1/+25
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.
