2013-02-14mfd: vexpress: Allow vexpress-sysreg to self-initialiseCatalin Marinas1-4/+6
The vexpress_sysreg_init() is a core_initcall() already and it can trigger the early initialisation if a matching node is found. This patch allows the SoC code to avoid calling vexpress_sysreg_of_early_init() explicitly.

2013-02-14mfd: rtsx: Implement driving adjustment to device-dependent callbacksRoger Tseng3-3/+29
Implement different ways of selecting driving capability(a necessary adjustment along with voltage change). It was origionally in device-independent mmc/host/rtsx_pci_sdmmc.c. Moving it here to support devices which may have a different way of adjustment.

2013-02-14mfd: rtsx: Optimize card detect flowWei WANG1-12/+19
1. Schedule card detect work at the end of the ISR 2. Callback function ops->cd_deglitch may delay for a period of time. It is not proper to call this callback when local irq disabled. 3. Card detect flow can't be executed in parallel with other card reader operations, so it's better to be protected by mutex.

The tps65090 mfd driver implement the suspend/resume callbacks which just disable and enable irqs in suspend/resume respectively. This operation is already done in irq suspend and irq_resume and hence it is not require to implement the same in the driver. Remove this non-require code.

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.
