2016-04-28clk: renesas: mstp: Use always-on governor for Clock DomainGeert Uytterhoeven
As a pure Clock Domain does not have the concept of powering the domain itself, the CPG/MSTP driver does not provide power_off() and power_on() callbacks. However, the genpd core may still perform a dummy power down, causing /sys/kernel/debug/pm_genpd/pm_genpd_summary to report the domain's status being "off-0". Use the always-on governor to make sure the domain is never powered down, and always shows up as "on" in pm_genpd_summary.

All local setup of the generic_pm_domain structure should have been completed before calling pm_genpd_init(). Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org>
2016-04-07clk: renesas: mstp: Clarify cpg_mstp_{at,de}tach_dev() domain parameterGeert Uytterhoeven
Make it clear that the "domain" parameter of the cpg_mstp_attach_dev() and cpg_mstp_detach_dev() functions is not used. The cpg_mstp_attach_dev() and cpg_mstp_detach_dev() callbacks are not only used by the CPG/MSTP Clock Domain driver, but also by the R-Mobile SYSC PM Domain driver.

2016-04-07clk: renesas: mstp: Drop check for CONFIG_PM_GENERIC_DOMAINS_OFGeert Uytterhoeven
As of commit 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains"), CONFIG_PM_GENERIC_DOMAINS_OF is always enabled for SoCs with MSTP clocks.

2016-03-15clk: renesas: Rename header file renesas.hSimon Horman
This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs. Along with the above mentioned Kconfig changes it seems appropriate to also rename files.

Along with the above mentioned Kconfig changes it seems appropriate to also rename directories that only hold drivers for such SoCs.
