PM / devfreq: exynos-bus: add missing of_node_put after calling of_parse_phandle

2016-07-06T04:11:24Z

of_node_put needs to be called when the device node which is got from of_parse_phandle has finished using.

PM / devfreq: exynos-ppmu: fix error path in exynos_ppmu_probe()

iounmap() needs to be called in case of memory allocation (for devfreq-event devices) failure. Fix it. Signed-off-by: Bartlomiej Zolnierkiewicz Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: exynos: fix error path in exynos_bus_probe()

2016-07-06T04:11:24Z

In case of exynos_bus_parse_of() failure the code shouldn't try to remove the OPP table and disable+unprepare bus->clk as it has been already handled in exynos_bus_parse_of(). Signed-off-by: Bartlomiej Zolnierkiewicz Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: make event/exynos-ppmu DEVFREQ_EVENT_EXYNOS_PPMU tristate

2016-07-06T04:11:23Z

The Kconfig currently controlling compilation of this code is: config DEVFREQ_EVENT_EXYNOS_PPMU bool "EXYNOS PPMU (Platform Performance Monitoring Unit) DEVFREQ event Driver" ...meaning that it currently is not being built as a module by anyone. Rather than rip out the existing modular code, Chanwoo indicated that he'd rather see the driver offered as tristate. I don't have the hardware for runtime validation, so this change is only validated for compile and modpost. Signed-off-by: Paul Gortmaker Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: make devfreq-event explicitly non-modular

2016-07-06T04:11:22Z

The Kconfig currently controlling compilation of this code is: menuconfig PM_DEVFREQ_EVENT bool "DEVFREQ-Event device Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. This code wasn't using module_init, so we don't need to be concerned with altering the initcall level here. We don't replace module.h with init.h since the file already has that. But we do add export.h since this file does export some symbols. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

PM / devfreq: Send the DEVFREQ_POSTCHANGE notification when target() is failed

2016-06-23T21:15:12Z

This patch sends the DEVFREQ_POSTCHANGE notification when devfreq->profile->targer() is failed. The PRECHANGE/POSTCHANGE should be paired.
