Markus Elfring 0637a4c781 clk/Renesas-MSTP: Use kmalloc_array() in cpg_mstp_clocks_init()
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".

This issue was detected by using the Coccinelle software.

Geert Uytterhoeven 20729300ca clk: renesas: mstp: Use always-on governor for Clock Domain
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.

Geert Uytterhoeven b3a52d75bc clk: renesas: mstp: Postpone call to pm_genpd_init()
All local setup of the generic_pm_domain structure should have been
completed before calling pm_genpd_init().

Geert Uytterhoeven 12a56817b3 clk: renesas: mstp: Clarify cpg_mstp_{at,de}tach_dev() domain parameter
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.

Geert Uytterhoeven 848fc67da5 clk: renesas: mstp: Drop check for CONFIG_PM_GENERIC_DOMAINS_OF
As of commit 71d076ceb2 ("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.

Simon Horman 09c32427c9 clk: renesas: Rename header file renesas.h
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.

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 directories that only hold drivers for such SoCs.
