[GIT PULL 00/12] Second Round of Renesas ARM based SoC Board updates for v3.14

[GIT PULL 00/12] Second Round of Renesas ARM based SoC Board updates for v3.14

[Simon Horman]

Hi Kevin, Hi Olof, Hi Arnd,

please consider the this second round of Renesas ARM based SoC board
updates for v3.14.

This pull request is based on a merge of:

* The first round of Renesas ARM based SoC board
  updates for v3.14, tagged as renesas-boards-for-v3.14,
  which you have already pulled.

* The second round of Renesas ARM based SoC
  updates for v3.14, tagged as renesas-soc-for-v3.14,
  which I have previously sent a pull-request for.

The reason for this merge is to provide SoC dependencies
used by the multiplatform and CCF changes in this series.


The following changes since commit 70d4f2e5576a16120e6bc85b10011032306c1179:

  Merge branch 'heads/soc2' into boards2-base (2013-12-19 19:08:11 +0900)

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

The Armadillo 800 EVA panel module has a backlight enable signal
connected to GPIO 61. Instead of requesting the GPIO in board code and
setting it to a high level unconditionally, pass the GPIO number to the
PWM backlight driver as the backlight enable GPIO.

[PATCH 06/12] ARM: shmobile: lager-reference: Instantiate clkdevs for SCIF and CMT

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Now that the common clock framework is supported, the clock lookup
entries in clock-r8a7790.c are not registered anymore. Devices must
instead reference their clocks in the device tree. However, SCIF and CMT
devices are still instantiated through platform code, and thus need a
clock lookup entry.

Retrieve the SCIF and CMT clock entries by name and register clkdevs for
the corresponding devices. This will be removed when the SCIF and CMT
devices will be instantiated from the device tree.

[PATCH 07/12] ARM: shmobile: koelsch-reference: Instantiate clkdevs for SCIF and CMT

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Now that the common clock framework is supported, the clock lookup
entries in clock-r8a7791.c are not registered anymore. Devices must
instead reference their clocks in the device tree. However, SCIF and CMT
devices are still instantiated through platform code, and thus need a
clock lookup entry.

Retrieve the SCIF and CMT clock entries by name and register clkdevs for
the corresponding devices. This will be removed when the SCIF and CMT
devices will be instantiated from the device tree.

[PATCH 08/12] ARM: shmobile: Remove non-multiplatform Lager reference support

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Now that r8a7790 has CCF support remove the legacy Lager reference
Kconfig bits CONFIG_MACH_LAGER_REFERENCE for the non-multiplatform
case.

Starting from this commit Lager board support is always enabled via
CONFIG_MACH_LAGER, and CONFIG_ARCH_MULTIPLATFORM is used to select
between board-lager.c and board-lager-reference.c

The file board-lager-reference.c can no longer be used together with
the legacy sh-clk clock framework, instead CCF is used.
