regulator: max8998: Convert to GPIO descriptors This rewrites the max8998 regulator driver to fetch the dvs regulators as descriptors. This will likely mostly come from the device tree since there are no in-tree users of the platform data, but supplying GPIO descriptor tables from board files is also possible if needed.

regulator: max8998: Add charger regulator The max8998 has a current regulator for charging control. The charger driver in drivers/power/supply/max8998_charger.c has a comment in it stating that 'charger control is done by a current regulator "CHARGER"', but this regulator was never added until now. The current values have been extracted from a downstream driver for the SGH-T959V.

regulator: max8998: Use arrays for specifying voltages in platform data This patch modifies the platform data of max8998 to use arrays for specifying predefined voltages of buck1 and buck2 instead of separate field for each voltage. This allows to simplify the code a bit and will help in adding support for Device Tree, which will be introduced in further patch.

mfd: max8998: Add irq domain support This patch adds irq domain support for max8998 interrupts. To keep both non-DT and DT worlds happy, simple domain is used, which is linear when no explicit IRQ base is specified and legacy, with static mapping, otherwise.

mfd: Support LP3974 RTC The first releases of LP3974 have a large delay in RTC registers, which requires 2 seconds of delay after writing to a rtc register (recommended by National Semiconductor's engineers) before reading it. If "rtc_delay" field of the platform data is true, the rtc driver assumes that such delays are required. Although we have not seen LP3974s without requiring such delays, we assume that such LP3974s will be released soon (or they have done so already) and they are supported by "lp3974" without setting "rtc_delay" at the platform data. This patch adds delays with msleep when writing values to RTC registers if the platform data has rtc_delay set.
