drivers: sh: Stop using the legacy clock domain on ARM

2016-05-30T00:41:11+00:00

Since commits 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains") and 2ee98234b88174f2 ("arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM Domains"), CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled unconditionally for Renesas ARM-based SoCs. Hence the legacy clock domain is no longer used on these SoCs. Remove the related support code, and stop entering drivers/sh/ on ARM. Signed-off-by: Geert Uytterhoeven Signed-off-by: Simon Horman

drivers: sh: Restore legacy clock domain on SuperH platforms

2016-02-25T00:05:19+00:00

CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms (which are DT based and multi-platform), but also on a select set of Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence since commit 0ba58de231066e47 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer installed on these SuperH platforms, and module clocks may not be enabled when needed, leading to driver failures. To fix this, add an additional check for CONFIG_OF. Fixes: 0ba58de231066e47 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI"). Signed-off-by: Geert Uytterhoeven Signed-off-by: Simon Horman

Shmobile is all multiplatform these days, so get rid of the reference to CONFIG_ARCH_SHMOBILE_MULTI. Signed-off-by: Geert Uytterhoeven Signed-off-by: Simon Horman

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

2015-09-14T01:20:23+00:00

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

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

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

2015-04-27T04:08:13+00:00

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.
