Merge tag 'renesas-soc-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc
Merge "Renesas ARM Based SoC Updates for v4.4" from Simon Horman: * ARM: shmobile: R-Mobile: Use CPG/MSTP Clock Domain attach/detach helpers This part of a multi-stage effort by Geert Uytterhoeven to add: "Clock Domain support to the Clock Pulse Generator (CPG) Module Stop (MSTP) Clocks driver using the generic PM Domain, to be used on shmobile SoCs without device power domains (R-Car Gen1 and Gen2, RZ). This allows to power-manage the module clocks of SoC devices that are part of the CPG/MSTP Clock Domain using Runtime PM, or for system suspend/resume, similar to SoCs with device power domains (SH-Mobile and R-Mobile)." * tag 'renesas-soc-for-v4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: shmobile: R-Mobile: Use CPG/MSTP Clock Domain attach/detach helpers clk: shmobile: mstp: Consider "zb_clk" suitable for power management
