Support voltage control for regulators on ROHM BD71815 PMIC. ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED). Bucks 1 and 2 support HW state based voltage level and enable states. Other regulators support HW state based enable states. All bucks and LDOs 1-5 allow voltage changes for RUN state and LDO4 can be enabled/disabled via GPIO. LDO3 does support changing between two predetermined voltages by using a GPIO but this functionality is not included in this commit. This work is derived from driver originally written by Tony Luo <luofc@embedinfo.com> - although not much of original work is left. Signed-off-by:

Most ROHM PMIC sub-devices only use the regmap pointer from parent device. They can obtain this by dev_get_regamap so in most cases the MFD device does not need to allocate and populate the driver data. Simplify drivers by removing this. The BD70528 still needs the access to watchdog mutex so keep rohm_regmap_dev in use on BD70528 RTC and WDG drivers for now. Signed-off-by:

The ROHM BD71828 and BD71815 RTC drivers only need the regmap pointer from parent. Regmap can be obtained via dev_get_regmap() so do not require parent to populate driver data for that. BD70528 on the other hand requires parent data to access the watchdog so leave the parent data for BD70528 here for now. Signed-off-by:

The charging algorithm header is only used locally in the power supply subsystem so push this down into drivers/power/supply and rename from the confusing "ux500_chargalg.h" to "ab8500-chargalg.h" for clarity: it is only used with the AB8500.

The global definition of platform data for the battery management code has no utility after the OF conversion, move the <linux/mfd/abx500/ab8500-bm.h> to be a local file in drivers/power/supply and stop defining the platform data in drivers/power/supply/ab8500_bmdata.c and broadcast to the kernel only to have it assigned as platform data to the MFD cells and then picked back into the same subsystem that defined it in the first place. This kills off a layer of indirection. Signed-off-by:
