[PATCH 01/11] ARM: shmobile: ape6evm: MP clock parent become EXTAL2

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

The orignal commit 3263e09d287fbaa8a9424b5e69396599a3bbd518
(ARM: shmobile: Initial r8a73a4 SoC support V3)
put MP clock parent as EXTAL2, but its code was removed
on DIV6 clock support commit.
This patch makes it consistent.

[PATCH 03/11] ARM: shmobile: kzm9d: resigser smsc911x platform device with id -1

[Simon Horman]

As the kzm9d only has one smsc911x device it
may be registered as a platform device with id -1.

This allows the kzm9d board to access the smsc911x device
when CONFIG_REGULATOR (and CONFIG_REGULATOR_FIXED_VOLTAGE)
are set. The motivation for which is twofold: using regulators
seems to be generally a good thing; it will move the kzm9d defconfig
one step closer to being able to be consolidated with other
shmobile defconfigs.

An alternate but so far untested approach would be to
update the definition of dummy_supplies in board-kzm9d.c
to use "smsc911x.0" instead of "smsc911x".

[PATCH 04/11] ARM: shmobile: kzm9g: add AS3711 PMIC platform data

[Simon Horman]

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>

KZM9G uses an AS3711 PMIC to supply power to the CPU and the LCD backlight.
The PMIC on the board is pre-programmed to supply correct voltages to the
CPU, power supply to the backlight has to be turned on at run-time. The
latter is currently performed by a hard-coded I2C command sequence in the
board file. This patch removes the backlight hack and instead adds an I2C
device to instantiate the AS3711 MFD driver, which will add a regulator
device to dynamically adjust CPU voltages and a backlight device.

[PATCH 08/11] ARM: shmobile: lager: support GPIO switches

[Simon Horman]

The lager board has pins 1 - 4 of SW2 wired up to GPIO pins.
This patch allows access to those pins as KEYS 1 - 4 using
gpio-keys.

[PATCH 09/11] ARM: shmobile: marzen: Use INTC External IRQ pin driver for SMSC

[Simon Horman]

Update the marzen board to use the INTC External IRQ pin driver for SMSC.

This code was originally posted by Magnus Damm as part of
"ARM: shmobile: INTC External IRQ pin driver on r8a7779"
but somehow omitted when I applied that patch.

[PATCH 10/11] ARM: shmobile: bockw: add SDHI0 support

[Simon Horman]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

This patch is directly accessing to PUPR4 register which can
control SDHI0 CD/WP pin pull-up setting.
It should be replaced in the future.
