[GIT PULL] Renesas ARM Based SoC r8a7740 CCF and Timers Updates for v3.18

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC r8a7740 CCF and timers updates
for v3.18.

These changes are in their own branch as there are SoC and board changes
that depend on DT changes, the reverse of the usual branch dependencies.


The following changes since commit 7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9:

  Linux 3.17-rc1 (2014-08-16 10:40:26 -0600)

Renesas ARM Based SoC R8a7740 CCF and Timers Updates for v3.18

When booting using the r8a7740/armadillo800eva using dt-reference:
* Use CCF to initialise clocks via DT
* Initialise timers via DT

[PATCH 2/8] ARM: shmobile: r8a7740: add SoC clocks to DTS

[Simon Horman]

From: Ulrich Hecht <ulrich.hecht+renesas@gmail.com>

Declares the r8a7740 clocks supported by the legacy clock framework,
excluding those requiring extensions to the DIV6 driver.

Now that r8a7740_add_standard_devices_dt() is just a wrapper for
of_platform_populate() call the latter directly.

This is in preparation for removing r8a7740_add_standard_devices_dt().

This pull request includes a minor conflict in
arch/arm/mach-shmobile/board-armadillo800eva-reference.c with
0eb07c96ee61be10 ("ARM: shmobile: armadillo800eva-reference: Sort
includes") which is included in the pull request
"Renesas ARM Based SoC Boards Cleanups For v3.18"
which is tagged as renesas-boards-cleanups-for-v3.18.

The resolution is to take both.
The resulting #includes should be:

#include <linux/clk.h>
#include <linux/err.h>
#include <linux/gpio.h>
#include <linux/io.h>
#include <linux/kernel.h>
#include <linux/of_platform.h>

This resolution can be found in the next branch of the renesas tree.

I have withdrawn the boards cleanup pull request and the

Thanks for splitting these out. I decided to put them into next/soc in the
end, since it didn't feel worth doing something special about them
