Merge tag 'renesas-boards-lager-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/boards2
From Simon Horman:
Renesas ARM based SoC lager board updates for v3.10
* Use r8a7790 timer setup code to force the
arch timer to be enabled regardless of the bootloader setting
- This is necessary for the lager board to boot
This pull request is based on:
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git renesas-boards3-for-v3.10
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git renesas-soc-r8a7790-for-v3.10
The merge was made to provide the r8a7790 timer setup code
* tag 'renesas-boards-lager-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
ARM: shmobile: use r8a7790 timer setup code on Lager
ARM: shmobile: force enable of r8a7790 arch timer
ARM: shmobile: Add second I/O range for r8a7790 PFC
