We delete the parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will be diverted to respective driver. Common registers are in dbx500-prcmu-regs.h and common accessors and defines in <linux/mfd/dbx500-prcmu.h> This way we get a a lot more abstraction and code reuse.

2011-10-24mfd: Disable twl6030 IRQ during suspendTodd Poynor
Module IRQs may still be disabled by DPM at the time the TWL6030 ISR runs, causing handle_simple_irq() to silently do nothing. This may result in missing TWL RTC alarm wakeups, for example, since the RTC child module ISR is not called to ack the IRQ. Disable the TWL6030 IRQ during suspend, enable it at DPM resume time, at which time the child module IRQs will be re-enabled.

2011-10-24mfd: Fix twl6030 lockdep recursion warning on setting wake IRQsTodd Poynor
LOCKDEP explicitly sets all irq_desc locks as a single lock-class, causing "possible recursive locking detected" when the TWL RTC driver calls through enable_irq_wake to twl6030_irq_set_wake, which recursively calls irq_set_irq_wake. Although the irq_desc and lock are different, LOCKDEP treats these as equivalent, presumably due to problems that can be incurred when locking more than one irq_desc, so best to avoid this. Suspend/resume actions implemented as PM notifiers to avoid touch the TWL core for this.

The codec for Devkit8000 (TWL4030) was not detected except when build with CONFIG_SND_SOC_ALL_CODECS. twl-core.c still uses the CONFIG_TWL4030_CODEC for twl_has_codec().

2011-10-24mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann
We currently have two symbols to control compilation the MFD subsystem, MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required at all, it only hides the submenu when not set, with the effect that Kconfig warns about missing dependencies when another driver selects an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu back from menuconfig into a plain menu simplifies the Kconfig syntax for those kinds of users and avoids the surprise when the menu suddenly appears because another driver was enabled that selects this symbol.
