[GIT PULL] Renesas ARM Based SoC DT Timers Updates for v3.18

[Simon Horman]

Hi Olof, Hi Kevin, Hi Arnd,

Please consider these Renesas ARM based SoC DT Timers updates for v3.18.

The patches in this pull request were originally posted as
"Renesas ARM Based SoC DT Timers Updates for v3.17" and tagged as
renesas-dt-timers-for-v3.17.  For various reasons it did not get
pulled for v3.17 so I have rebased it on v3.17-rc1 and am submitting
it for v3.18.


The following changes since commit 7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9:

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

are available in the git repository at:

[PATCH 7/8] ARM: shmobile: r7s72100: Add MTU2 device to DT

[Simon Horman]

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

Add the MTU2 counter to the r7s72100 device tree and make it disabled by
default.

[PATCH 8/8] ARM: shmobile: genmai-reference: Enable MTU2 in device tree

[Simon Horman]

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

No more device needs to be added from platform code when booting the
reference platform, move MTU2 registration from setup-r7s72100.c to
board-genmai.c and remove the now empty r7s72100_add_dt_devices()
function.

As the genmai_add_standard_devices() function is now identical to the
default init_machine implementation, remove it as well.
