PM / devfreq: Remove ARCH_HAS_OPP completely

2014-09-29T09:54:11Z

The Kconfig symbol ARCH_HAS_OPP became redundant in v3.16: commit 049d595a4db3 ("PM / OPP: Make OPP invisible to users in Kconfig") removed the only dependency that used it. Setting it had no effect anymore. So commit 78c5e0bb145d ("PM / OPP: Remove ARCH_HAS_OPP") removed it. For some reason that commit did not remove all select statements for that symbol. These statements are now useless. Remove one from devfreq too. Signed-off-by: Paul Bolle Signed-off-by: MyungJoo Ham

PM / OPP: Remove ARCH_HAS_OPP

2014-07-22T22:51:30Z

Since the OPP layer is a kernel library which has been converted to be directly selectable by its callers rather than user selectable and requiring architectures to enable it explicitly the ARCH_HAS_OPP symbol has become redundant and can be removed. Do so. Signed-off-by: Mark Brown Reviewed-by: Viresh Kumar Acked-by: Nishanth Menon Acked-by: Rob Herring Acked-by: Shawn Guo Acked-by: Simon Horman Signed-off-by: Rafael J. Wysocki

PM / devfreq: remove checks for CONFIG_EXYNOS_ASV

2014-05-24T13:33:51Z

Checks for CONFIG_EXYNOS_ASV were added in v3.3. But the related Kconfig symbol has never been added to the tree. Remove these checks, as they always evaluate to false. Signed-off-by: Paul Bolle [Merge conflict resolved by MyungJoo] Signed-off-by: MyungJoo Ham

PM / devfreq: exynos5: Add CONFIG_PM_OPP dependency to fix probe fail

2014-05-24T08:56:38Z

This patch add CONFIG_PM_OPP dependecy to exynos5_bus driver to fix probe fail. If CONFIG_PM_OPP is disabled, dev_pm_opp_find_freq_floor() will always return ERR_PTR(-EINVAL) error. Signed-off-by: Chanwoo Choi Reviewed-by: Tomasz Figa Signed-off-by: MyungJoo Ham

PM / devfreq: exynos4: Add CONFIG_PM_OPP dependency to fix probe fail

2014-05-24T08:56:37Z

This patch add CONFIG_PM_OPP dependecy to exynos4_bus driver to fix probe fail as following log: [ 3.721389] exynos4-busfreq busfreq.3: Fail to add opp entries. [ 3.721697] exynos4-busfreq: probe of busfreq.3 failed with error -22 If CONFIG_PM_OPP is disabled, dev_pm_opp_find_freq_floor() in xxx_probe() will always return -EINVAL error.

PM / devfreq: Disable Exynos4 driver build on multiplatform

2014-01-27T22:21:30Z

Exynos4 devfreq driver uses mach/map.h which is not available on multiplatform. Hence disable build on multiplatform for now. Without this patch we get the following build errors: drivers/devfreq/exynos/exynos4_bus.h:15:22: fatal error: mach/map.h: No such file or directory Signed-off-by: Sachin Kamat Signed-off-by: Rafael J.

PM / devfreq: fix typo "CPU_EXYNOS4.12" twice

2013-06-03T11:20:29Z

Dependencies on CPU_EXYNOS4212 and CPU_EXYNOS4412 for the "ARM Exynos4210/4212/4412 Memory Bus DEVFREQ Driver" were added in commit 7b4050381127ae11fcfc74a106d715a5fbbf888a ("PM/Devfreq: Add Exynos4-bus device DVFS driver for Exynos4210/4212/4412."). The tree (at that time, v3.3, and currently) makes clear that this should have been dependencies on SOC_EXYNOS4212 and SOC_EXYNOS4412. Signed-off-by: Paul Bolle

PM / devfreq: Add Exynos5-bus devfreq driver for Exynos5250

2013-06-03T11:20:29Z

Exynos5-bus device devfreq driver monitors PPMU counters and adjusts operating frequencies and voltages with OPP. ASV should be used to provide appropriate voltages as per the speed group of the SoC rather than using a constant 1.025V.

PM / devfreq: governors: add GPL module license and allow module build

2012-11-20T09:46:23Z

Add GPL module license and remove the static build restrictions for building governors.
