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

2015-09-14T01:20:23Z

If the default PM Domain using PM_CLK is used for PM runtime, the real Clock Domain cannot be registered from DT later. Hence do not enable it when running a multi-platform kernel with genpd support on R-Car or RZ. The CPG/MSTP Clock Domain driver will take care of PM runtime management of the module clocks. Now most multi-platform ARM shmobile platforms (SH-Mobile, R-Mobile, R-Car, RZ) use DT-based PM Domains to take care of PM runtime management of the module clocks, simplify the platform logic by replacing the explicit SoC checks by a single check for the presence of MSTP clocks in DT. Backwards-compatiblity with old DTs (mainly for R-Car Gen2) is provided by checking for the presence of a "#power-domain-cells" property in DT. The default PM Domain is still needed for: - backwards-compatibility with old DTs that lack PM Domain properties, - the CONFIG_PM=n case, - legacy (non-DT) ARM/shmobile platforms without genpd support (r8a7778, r8a7779), - legacy SuperH.

drivers: sh: Disable legacy default PM Domain on emev2

2015-09-14T01:20:22Z

EMMA Mobile EV2 doesn't have MSTP clocks. All its device drivers manage clocks explicitly, without relying on Runtime PM, so it doesn't need the legacy default PM Domain. Signed-off-by: Geert Uytterhoeven Reviewed-by: Ulf Hansson Signed-off-by: Simon Horman

drivers: sh: remove boilerplate code and use USE_PM_CLK_RUNTIME_OPS

2015-05-12T21:55:38Z

USE_PM_CLK_RUNTIME_OPS is introduced so we don't repeat the same code to do runtime_suspend and runtime_resume across users of PM clocks. Use it to remove the boilerplate code.

drivers: sh: Disable PM runtime for multi-platform r8a73a4 with genpd

2015-04-27T04:08:13Z

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 r8a73a4. 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.
