Merge tag 'renesas-soc-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc
From Simon Horman: Renesas ARM-based SoC updates for v3.11 * Increased clock coverage for r8a7740, r8a73a4, r8a7778 and r8a7790 * Use fixed clock ratio for r8a7778 * Always use shmobile_setup_delay for sh73a0 * Add add CPUFreq support for sh73a0 * Check kick bit before changing rate on sh73a0 * Do not overwrite all div4 clock operations on sh73a0 * Cleanup SH_FIXED_RATIO_CLK and SH_FIXED_RATIO_CLK macros * sh73a0: Use DEFINE_RES_MEM*() everywhere * r8a7740: Make private clock arrays static * r8a7778: Correct model number The last four changes listed above are cleanups. I have included them in this series as all bar the last one are dependencies of non-cleanup patches. * tag 'renesas-soc-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (27 commits) ARM: shmobile: sh73a0: div4 clocks must check the kick bit before changing rate ARM: shmobile: sh73a0: do not overwrite all div4 clock operations ARM: shmobile: sh73a0: Always use shmobile_setup_delay() ARM: shmobile: sh73a0: add CPUFreq support ARM: shmobile: sh73a0: add support for adjusting CPU frequency ARM: shmobile: r8a7790: add TPU PWM support ARM: shmobile: r8a7790: Make private clock arrays static ARM: shmobile: r8a7790: add div6 clocks ARM: shmobile: r8a7790: add div4 clocks ARM: shmobile: r8a7790: add main clock ARM: shmobile: r8a7778: Register SDHI device ARM: shmobile: r8a7778: add SDHI clock support ARM: shmobile: r8a7778: use fixed ratio clock ARM: shmobile: r8a7779: Add PCIe clocks ARM: shmobile: r8a73a4: add div6 clocks ARM: shmobile: r8a73a4: add div4 clocks ARM: shmobile: r8a73a4: add pll clocks ARM: shmobile: r8a73a4: add main clock ARM: shmobile: r8a7740: add TPU PWM support ARM: shmobile: r8a7740: Add I2C DT clock names ...
