PM / devfreq: Export helper functions for drivers

2014-09-29T11:22:22Z

These functions are indended for use by drivers and should be available also when the driver is built as a module. Cc: MyungJoo Ham Cc: Kyungmin Park Signed-off-by: Ãrjan Eide Signed-off-by: MyungJoo Ham

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: Use devm_devfreq_* function using device resource management

PM / devfreq: Add devm_devfreq_{register,unregister}_opp_notfier function

2014-05-24T13:33:41Z

This patch add resource-managed function for devfreq opp as following functions.

PM / devfreq: Fix devfreq_remove_device() to improve the sequence of resource free

2014-05-24T13:33:34Z

This patch modify devfreq_remove_device() to improve the sequence of resource free. If executing existing devfreq_remove_device(), this function always executes _remove_devfreq() twice. In result, second _remove_devfreq() always return error value. So, This patch resolves complicated function sequence as following: [Flow sequence before modification] devfreq_remove_device() _remove_devfreq(devfreq, false) kfree(devfreq); /* Free devfreq */ if (!skip ...) { /* skip is false */ device_unregister(&devfreq->dev) put_device(&devfreq->dev); ... dev->release() devfreq_dev_release() _remove_devfreq(devfreq, true) <- Recall to free devfreq /* * Always return error without freeing resource because * already _remove_devfreq() frees the memory of devfreq. */ } [Flow sequence after modification] devfreq_remove_device device_unregister(&devfreq->dev) put_device(&devfreq->dev); .. dev->release() devfreq_dev_release() _remove_devfreq() kfree(devfreq); /* Free devfreq */ Signed-off-by: Chanwoo Choi [Merge conflict resolved by MyungJoo] Signed-off-by: MyungJoo Ham
