drivers: sh: Disable PM runtime for multi-platform r8a7740 with genpd

2015-02-23T22:26:12Z

If the default PM domain using PM_CLK is used for PM runtime, the real PM domain(s) cannot be registered from DT later. Hence do not enable it when running a multi-platform kernel with genpd support on an r8a7740. The R-Mobile PM domain driver will take care of PM runtime management of the module clocks. The default PM domain is still needed for: - platforms without genpd support, - the legacy (non-DT) case, where genpd may take over later, except for the C5 "always on" PM domain.

drivers: sh / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T02:08:24Z

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM in drivers/sh/pm_runtime.c. Signed-off-by: Rafael J. Wysocki Acked-by: Simon Horman Acked-by: Geert Uytterhoeven

drivers: sh: Leave disabling of unused PM domains to genpd

sh: intc: Confine SH_INTC to platforms that need it

2014-08-22T03:28:16Z

Currently the sh-intc driver is compiled on all SuperH and non-multiplatform SH-Mobile platforms, while it's only used on a limited number of platforms: - SuperH: SH2(A), SH3(A), SH4(A)(L) (all but SH5) - ARM: sh7372, sh73a0 Drop the "default y" on SH_INTC, make all CPU platforms that use it select it, and protect all sub-options by "if SH_INTC" to fix this.

drivers: sh: pm_runtime implementation needs to suspend and resume devices

2014-05-26T01:45:06Z

If we override the platform bus calls for pm_runtime then we end up with the calls to the devices' suspend and resume methods ignored in favour of the bus ones. Change to calling the pm_runtime calls to suspend and resume the devices specifically in the drivers/sh/pm_runtime.c implementation to allow any device that may want to run power management to do so. Note, all the current sh driver implementations do not use their own power management code so this is not a major implementation issues. This also brings the implementation into line with the versions used by the Davinci and Keystone PM domain code, so once fully tested these implementations could be merged together.
