PM / devfreq: exynos-ppmu: Staticize event list

2017-06-12T01:12:07Z

The ppmu_events array is accessed only in this compilation unit so it can be made static. Signed-off-by: Krzysztof Kozlowski Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-ppmu: Handle return value of clk_prepare_enable

2017-06-12T01:12:07Z

clk_prepare_enable() can fail here and we must check its return value. Signed-off-by: Arvind Yadav Signed-off-by: MyungJoo Ham

clk_prepare_enable() can fail here and we must check its return value. Signed-off-by: Arvind Yadav Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-ppmu: Show the registred device for ppmu device

2017-01-31T05:12:20Z

This patch just adds the simple log to show the PPMU device's registration during the kernel booting.

PM / devfreq: exynos-ppmu: Use the regmap interface to handle the registers

2017-01-31T05:12:19Z

This patch uses the regmap interface to read and write the registers for exynos PPMU device instead of the legacy memory map functions. Signed-off-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-ppmu: Remove unused mutex from struct exynos_ppmu

2016-11-17T02:31:28Z

The mutex is not used at all, remove it. Signed-off-by: Axel Lin Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-ppmu: ppmu_events array should not be NULL terminated

2016-11-17T02:31:28Z

The rest of the code uses ARRAY_SIZE to count the number of entries in ppmu_events array. The NULL terminated entry makes ARRAY_SIZE return off-by-one value. Signed-off-by: Axel Lin Acked-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-ppmu: Fix module autoload

2016-11-17T02:31:28Z

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/devfreq/event/exynos-ppmu.ko | grep alias $ After this patch: $ modinfo drivers/devfreq/event/exynos-ppmu.ko | grep alias alias: of:N*T*Csamsung,exynos-ppmu-v2C* alias: of:N*T*Csamsung,exynos-ppmu-v2 alias: of:N*T*Csamsung,exynos-ppmuC* alias: of:N*T*Csamsung,exynos-ppmu Signed-off-by: Javier Martinez Canillas Signed-off-by: MyungJoo Ham
