Merge tag 'renesas-soc-r8a7790-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc2
From Simon Horman: Renesas ARM based r8a7790 SoC update for v3.10 * Force architecture timer to be activated regardless of bootloader - This is necessary for the lager board to boot * Add second memory range to r8a7790 PFC device - This is in preparation for further PFC work. It should not break anything as it is not used yet. This pull request is based on: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git renesas-soc2-for-v3.10 * tag 'renesas-soc-r8a7790-for-v3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: force enable of r8a7790 arch timer ARM: shmobile: Add second I/O range for r8a7790 PFC Signed-off-by: Olof Johansson <olof@lixom.net>
