When the cell data_size is 0, the resulting platform_data pointer will be set to ZERO_SIZE_PTR. That could be misleading for device drivers running a NULL check on thei platform_data pointer before dereferencing it.

The mfd driver for MC13783 recently got support for MC13892 and was renamed accordingly from mc13783-core to mc13xxx-core. Do the same for rtc-mc13783. The only relevant change is to use platform id's to tell the platform bus that this driver is responsible for mc13892-rtc devices, too.

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.

mc13892 is the companion PMIC for Freescale's i.MX51. It's similar enough to mc13782 to support it in a single driver. This patch introduces enough compatibility cruft to keep all users of the superseded mc13783 driver unchanged.

The regulator driver was converted to get the needed data directly from platform_data by a10099bc (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.

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.

In some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly connected to the sh_mmcif controller, so that polling needs to be used. To overcome the overhead induced by querying the controller on each poll cycle, card detection can be handled in the platform code more efficiently. This patch exposes a get_cd hook for that purpose.
