This patchset support devicetree and use common ppmu driver instead of individual code of exynos4_bus.c to remove duplicate code. Also this patchset get the resources for busfreq from dt data by using DT helper function. - PPMU register address - PPMU clock - Regulator for INT/MIF block This patchset use SET_SYSTEM_SLEEP_PM_OPS macro intead of legacy method. To remove power-leakage in suspend state, before entering suspend state, disable ppmu clocks. Changes from v1: - Add exynos4_bus.txt documentation for devicetree guide - Fix probe failure if CONFIG_PM_OPP is disabled - Fix typo and resource leak(regulator/clock/memory) when happening probe failure - Add additionally comment for PPMU usage instead of previous PPC - Split separate patch to remove ambiguous of patch Chanwoo Choi (8): devfreq: exynos4: Support devicetree to get device id of Exynos4 SoC devfreq: exynos4: Use common ppmu driver and get ppmu address from dt data devfreq: exynos4: Add ppmu's clock control and code clean about regulator control devfreq: exynos4: Fix bug of resource leak and code clean on probe() devfreq: exynos4: Use SET_SYSTEM_SLEEP_PM_OPS macro devfreq: exynos4: Fix power-leakage of clock on suspend state devfreq: exynos4: Add CONFIG_PM_OPP dependency to fix probe fail devfreq: exynos4: Add busfreq driver for exynos4210/exynos4x12 .../devicetree/bindings/devfreq/exynos4_bus.txt | 49 +++ drivers/devfreq/Kconfig | 1 + drivers/devfreq/exynos/Makefile | 2 +- drivers/devfreq/exynos/exynos4_bus.c | 415 ++++++++++++++------- 4 files changed, 341 insertions(+), 126 deletions(-) create mode 100644 Documentation/devicetree/bindings/devfreq/exynos4_bus.txt -- 1.8.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
