[PATCH v5 00/14] Add Maxim 77802 PMIC support

MAX77802 is a PMIC that contains 10 high efficiency Buck regulators,
32 Low-dropout (LDO) regulators, two 32kHz buffered clock outputs,
a Real-Time-Clock (RTC) and a I2C interface to program the individual
regulators, clocks and the RTC.

This fifth version of the patch-set addresses several issues pointed
out by Krzysztof Kozlowski and Yadwinder Singh Brar. The individual
changes are added on each patch change log.

This series are based on drivers added by Simon Glass to the Chrome OS
kernel and adds support for the Maxim 77802 Power Management IC, their
regulators, clocks, RTC and I2C interface.

NOTE: This version of the series model the real power scheme for Maxim
77802 regulators instead of a simplistic model like in older versions.
So these changes depend on patch:

"[PATCH v3] ARM: dts: Add cros_ec to exynos5420-peach-pit and exynos5800-peach-pi"
https://patchwork.kernel.org/patch/4411351/

which adds tps65090 support to Peach boards since regulators from this
PMIC supply power to a set of MAX77802 regulators.

The patch-set has been tested on both Daisy/Snow (max77686) and Peach
pit (max77802) Chromebooks and it's composed of the following patches:

Doug Anderson (1):
  mfd: max77686: Allow the max77686 rtc to wakeup the system

Javier Martinez Canillas (13):
  mfd: max77686: Convert to use regmap_irq
  clk: max77686: Add DT include for MAX77686 PMIC clock
  clk: max77686: Improve Maxim 77686 PMIC clocks binding
  clk: Add generic driver for Maxim PMIC clocks
  clk: max77686: Convert to the generic max clock driver
  mfd: Add driver for Maxim 77802 Power Management IC
  mfd: max77802: Add DT binding documentation
  regmap: Add regmap_reg_copy function
  regulator: Add driver for Maxim 77802 PMIC regulators
  clk: Add driver for Maxim 77802 PMIC clocks
  clk: max77802: Add DT binding documentation
  rtc: Add driver for Maxim 77802 PMIC Real-Time-Clock
  ARM: dts: Add max77802 to exynos5420-peach-pit and exynos5800-peach-pi
