Pull devfreq updates for v5.6 from Chanwoo Choi: "1. Update devfreq core - Add new 'name' attribute of sysfs to show the device name : /sys/class/devfreq/devfreqX/name - Make 'trans_stat' sysfs reset by entering zero(0) : echo 0 > /sys/class/devfreq/devfreqX/trans_stat - Add debugfs support with 'devfreq_summary' to show the summary : /sys/kernel/debug/devfreq/devfreq_summary - Change the type of time variable to 64bit to avoid overflows. - Make separate devfreq_stats including the statistics information. - Fix minor coding-style like indentation and kernel-doc warnings. 2. Update devfreq drivers - 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 drivers - Fix excessive stack usage of exynos-ppmu.c and clean-up code of rockchip-dfi.c without behavior changes." * tag 'devfreq-next-for-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux: (24 commits) PM / devfreq: Add debugfs support with devfreq_summary file PM / devfreq: exynos: Rename Exynos to lowercase PM / devfreq: imx8m-ddrc: Fix inconsistent IS_ERR and PTR_ERR PM / devfreq: exynos-bus: Add error log when fail to get devfreq-event PM / devfreq: exynos-bus: Disable devfreq-event device when fails PM / devfreq: rk3399_dmc: Disable devfreq-event device when fails PM / devfreq: imx8m-ddrc: Remove unused defines PM / devfreq: exynos-bus: Reduce goto statements and remove unused headers PM / devfreq: rk3399_dmc: Add COMPILE_TEST and HAVE_ARM_SMCCC dependency PM / devfreq: rockchip-dfi: Convert to devm_platform_ioremap_resource PM / devfreq: rk3399_dmc: Add missing of_node_put() PM / devfreq: rockchip-dfi: Add missing of_node_put() PM / devfreq: Fix multiple kernel-doc warnings PM / devfreq: exynos-bus: Extract exynos_bus_profile_init_passive() PM / devfreq: exynos-bus: Extract exynos_bus_profile_init() PM / devfreq: Move declaration of DEVICE_ATTR_RW(min_freq) PM / devfreq: Move statistics to separate struct devfreq_stats PM / devfreq: Add clearing transitions stats PM / devfreq: Change time stats to 64-bit PM / devfreq: Add new name attribute for sysfs ...
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
