• 735a3d9ef   regulator: Support MAX8998/LP3974 DVS-GPIO ... Browse Code »

  The previous driver did not support BUCK1-DVS3, BUCK1-DVS4, and
  BUCK2-DVS2 modes. This patch adds such modes and an option to block
  setting buck1/2 voltages out of the preset values.

• 337ce5d1c   mfd: Support LP3974 RTC ... Browse Code »

  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.

  Acked-by: Mark Brown

  This patch adds voltage regulator driver for Maxim 8998 chip. This chip
  is used on Samsung Aquila and GONI boards and provides following
  functionalities:
  - 4 BUCK voltage converters, 17 LDO power regulators and 5 other power
  controllers
  - battery charger

  This patch adds basic driver for voltage regulators and MAX 8998 MFD core.
