| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: Adding twl6030 mmc card detect support for MMC1kishore kadiyala2010-10-292-2/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mmc: Allow the platform to specify the sh_mmcif get_cd handlerArnd Hannemann2010-10-291-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: Allow the platform to specify the sh_mobile_sdhi get_cd handlerArnd Hannemann2010-10-291-0/+13
| | | | | | | | | | | | | | | | | | | | | | On some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly connected to the sdhi hardware, so that polling needs to be used with tmio_mmc and card detection is handled in the platform code. This patch allows to set tmio_mmc capabilities (to pass the MMC_CAP_NEEDS_POLL flag) and exposes a get_cd hook for that purpose.

| * mmc: Allow the tmio_mmc mfd driver to specify get_cd handlerArnd Hannemann2010-10-291-0/+13
| | | | | | | | | | | | | | | | | | | | Some controllers, supported by the tmio_mmc driver do not have the card detect pin of a slot connected, so that polling needs to be used and card detection is handled by other means. This patch exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
