PM / devfreq: Add debugfs support with devfreq_summary file (2020-01-16 19:14:49 +0900)
---------------------------------------------------------------- Detailed description for this pull request: 1. Update devfreq core - Add new 'name' attribute of sysfs to show the device name : /sys/class/devfreq/devfreqX/name
- Make 'trans_stat' sysfs resetting by entering zero(0) as following : echo 0 > /sys/class/devfreq/devfreqX/trans_stat
- Add debugfs support with 'devfreq_summary' file to show the summary : /sys/kernel/debug/devfreq/devfreq_summary
- Change the type of time variable to 64bit to prevent the overflow - Make the separate devfreq_stats including the statistics information - Fix the minor coding-style like indentation and kernel-doc warnings
2. Update devfreq driver - Add new imx8m-ddrc.c devfreq driver for dynamic scaling of DDR frequency. It changes the DDR frequency by using ARM SMCCC(SMC Calling Convention) interface to control TF-A firmware.
- Add COMPILE_TEST dependency for rk3399_dmc.c
- Clean-up code for exynos-bus.c and rk3399_dmc.c without behavior changes
3. Update devfreq-event driver - Fix excessive stack usage of exynos-ppmu.c and clean-up code of rockchip-dfi.c without behavior changes ----------------------------------------------------------------
