2010-10-29mfd: Factor out WM831x I2C I/O from the core driverMark Brown
In preparation for the addition of SPI support for the WM831x move the I2C specific code into a separate file with a separate Kconfig option so the I2C support can be excluded from the build. Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new symbol. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

The chip TRM documentation contradicts itself about this bit, page 174 of swcu050e says bit should be 0 for clear-on-read behavior, while page 487 says it should be 1.

2010-10-29mfd: Adding twl6030 mmc card detect support for MMC1kishore kadiyala
Adding card detect callback function and card detect configuration function for MMC1 Controller on OMAP4. Card detect configuration function does initial configuration of the MMC Control & PullUp-PullDown registers of Phoenix. For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect, the suspend/resume initialization which was done in omap_hsmmc_gpio_init previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

2010-10-29mfd: Remove obsolete mc13783 private dataUwe Kleine-König
The regulator driver was converted to get the needed data directly from platform_data by a10099b (regulator/mc13783: various cleanups) so regulators and num_regulators can go away. Then apart from the flag indicating that the adc does a conversion, flags is only a copy of the flags member of platform_data. This flag isn't needed to be returned by mc13783_get_flags, so mc13783_get_flags now gets the flags from platform_data, too and the driver private member is renamed for clearity.

2010-10-29ARM: mach-shmobile: ap4evb: Fix hotplug for SDHI1Arnd Hannemann
On AP4EVB the card detect pin of the top SD/MMC slot is not directly connected to the tmio/mmcif controller but to a GPIO pin, so polling needs to be done for SDHI1 and MMCIF in order to support hotplug for that slot. SHDI1 and MMCIF share that slot, and the used controller is selected by a DIP switch. This patch adds a helper function to check if a card is present in that particular slot, registers this function with SDHI1 and MMCIF and enables polling for SDHI1.
