[PATCH v3 0/7] Add max77802 support for Peach boards

[Javier Martinez Canillas]

Hello Kukjin,

This is a third version of th series that adds max77802 support for
the Peach Pit and Pi boards. The series also have all the pending
patches that were posted but depended on this support. I've picked
all the patches I found and rebased them to be sure that they apply
cleanly on top of linux-next. Also I've taken some DT snippets from
the downstream Chrome OS 3.8 kernel DTS for devices that use one of
these regulators as their input supply.

Changes since v2 [0]:
 - Remove left over supply on ldo35 regulator, suggested by Doug Anderson.
 - Add a patch to change the i2c7 clock at 400kHz, suggested by Doug Anderson.
 - Add a patch from Vivek Gautam to enable max77802 regulator driver support.

Changes sinve v1 [1]:
 - Dropped patch that added vmmc and vqmmc supplies as suggested
   by Doug Anderson.
 - Use IRQ flags define instead of a magic number as suggested by
   Andreas Faerber.

The series is composed of the following patches:

Javier Martinez Canillas (3):
  ARM: dts: Add Peach Pit and Pi dts entry for max77802 PMIC
  ARM: dts: Add Peach Pit and Pi dts entry for ISL29018 sensor
  ARM: dts: Set i2c7 clock at 400kHz for Peach boards

Naveen Krishna Chatradhi (1):
  ARM: dts: Add thermistor dts fragment used by exynos based Peach
    boards

Rahul Sharma (2):
  ARM: dts: add hdmi regulators for exynos5800 based peach-pi board
  ARM: dts: add hdmi regulators for exynos5420 based peach-pit board

Vivek Gautam (1):
  ARM: exynos_defconfig: Enable MAX77802

[PATCH v3 1/7] ARM: dts: Add Peach Pit and Pi dts entry for max77802 PMIC

[Javier Martinez Canillas]

Exynos5420 based Peach Pit and Exynos5800 based Peach Pi boards
uses a Maxim 77802 power management IC to drive regulators and
its Real Time Clock. This patch adds support for this chip.

These are the device nodes and pinctrl configuration that
are present on the Peach pit DeviceTree source file in the
the Chrome OS kernel 3.8 tree.

[PATCH v3 5/7] ARM: dts: Add Peach Pit and Pi dts entry for ISL29018 sensor

[Javier Martinez Canillas]

The Exynos5420 based Peach Pit and the Exynos5800 based Peach Pi
machines have an i2c ISL29018 light sensor. This patch adds the
device nodes needed to support this device.

These DTS snippets were taken from the downstream Chrome OS 3.8
kernel Device Tree for Peach Pit and Pi boards.
