[PATCH v6 00/23] Add Maxim 77802 PMIC support

[Javier Martinez Canillas]

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 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 and 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.

This is a sixth version of the patch-set that addresses several issues
pointed out in v5. Individual changes are added on each patch change log.

The biggest change is that now the MAX77686 mfd driver is extended to
also support the MAX77802 PMIC instead of having a separate mfd driver
as was suggested by Lee Jones.

Patches 1-16 are cleanups and improvements to the MAX77686 PMIC driver
as a preparation to also support the MAX77802 PMIC. Patch 17 adds support
for MAX77802 to the MAX77686 mfd driver and Patch 18 adds the DT binding
doc for this PMIC. Patch 19 adds support for the regulators in the PMIC,
Patch 20 adds support for the clocks in the PMIC and Patch 21 adds its DT
binding. Patch 22 adds support for the Real-Time-Clock found in the PMIC
and Patch 23 adds the needed device nodes for the max77802 to the Exynos5
base Peach Pit and Pi boards device tree source files.

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

  rtc: max77686: Allow the max77686 rtc to wakeup the system
