PM / devfreq: rk3399_dmc: Add COMPILE_TEST and HAVE_ARM_SMCCC dependency

2020-02-24T07:36:41Z

[ Upstream commit eff5d31f7407fa9d31fb840106f1593399457298 ] To build test, add COMPILE_TEST depedency to both ARM_RK3399_DMC_DEVFREQ and DEVFREQ_EVENT_ROCKCHIP_DFI configuration. And ARM_RK3399_DMC_DEVFREQ used the SMCCC interface so that add HAVE_ARM_SMCCC dependency to prevent the build break.

PM / devfreq: exynos-ppmu: Fix excessive stack usage

2020-02-24T07:36:41Z

[ Upstream commit d4556f5e99d5f603913bac01adaff8670cb2d08b ] Putting a 'struct devfreq_event_dev' object on the stack is generally a bad idea and here it leads to a warnig about potential stack overflow: drivers/devfreq/event/exynos-ppmu.c:643:12: error: stack frame size of 1040 bytes in function 'exynos_ppmu_probe' [-Werror,-Wframe-larger-than=] There is no real need for the device structure, only the string inside it, so add an internal helper function that simply takes the string as its argument and remove the device structure.

PM / devfreq: events: extend events by type of counted data

2019-08-25T03:44:38Z

This patch adds posibility to choose what type of data should be counted by the PPMU counter. Now the type comes from DT where the event has been defined. When there is no 'event-data-type' the default value is used, which is 'read+write data in bytes'. It is needed when you want to know not only read+write data bytes but i.e. only write data in byte, or number of read requests, etc. Signed-off-by: Lukasz Luba Acked-by: Chanwoo Choi [Updated property by MyungJoo. data_type --> event_type] Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-events: change matching code during probe

2019-08-25T03:36:47Z

The patch changes the way how the 'ops' gets populated for different device versions. The matching function now uses 'of_device_id' in order to identify the device type. Signed-off-by: Lukasz Luba Signed-off-by: Chanwoo Choi Signed-off-by: MyungJoo Ham

PM / devfreq: events: add Exynos PPMU new events
