2011-10-24mfd: Set twl6030 irq_wake infrastructure upSantosh Shilimkar1-0/+9
TWL6030 devices have an interrupt line which is connected to application processor like OMAP. These devices support multiple features such as MMC card detect, USB cable detect, RTC interrupt, etc. that must wake up the application processor. With this change, TWL6030 client drivers can make use of irq_wake() if the wakeup is desirable on it's irq events.

2011-10-24mfd: Support software initiated shutdown of WM831x PMICsMark Brown3-0/+27
In systems where there is no hardware signal from the processor to the PMIC to initiate the final power off sequence we must initiate the shutdown with a register write to the PMIC. Support such systems in the driver. Since this may prevent a full shutdown of the system platform data is used to enable the feature.

2011-10-24mfd: Fix twl4030 dependencies for audio codecThomas Weber1-1/+1
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(). In commit 57fe7251f5bfc4332f24479376de48a1e8ca6211 the CONFIG_TWL4030_CODEC was renamed into CONFIG_MFD_TWL4030_AUDIO, thatswhy the codec was not detected. This patch renames the CONFIG_ TWL4030_CODEC into CONFIG_MFD_TWL4030_AUDIO in twl-core.c.

2011-10-24mfd: remove CONFIG_MFD_SUPPORTArnd Bergmann1-18/+4
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.
