Detailed description for this pull request: 1. Update devfreq core - Add support delayed timer for polling mode. Until now, the devfreq supports only deferrable timer for reducing the unneeded CPU wakeup. But, it has a problem for Non-CPU device like DMC device with DMA operation. These Non-CPU device need to monitor continuously regardless of CPU state. Add support the delayed timer for polling mode to support the continuous monitoring. - Fix indentation of result of devfreq_summary debugfs node. - Fix the wrong end of code with semicolon instead of comma - Clean-up code to use the unified local variable name in sysfs-related internal funcitons. - Fix trivial spelling for devfreq-event.c. 2. Update devfreq driver - Add the exception handling code to control when rockchip,pmu property is absent for rk3399_dmc.c. - Add missing 'rockchip,pmu' property to dt-binding document for rk3399_dmc.c. - Change the kind of timer of exynos5422-dmc.c from deferrable to delayed timer in order to monitor the DMC (Dynamic Memory Controller) status regardless of CPU idle state. And adjust the polling interval and upthreshold value in order to react faster and make better decisions when benchmarking testing for the memory behavior. - Add module parameter to either enable or disable the IRQ mode for DMC behavior monitoring. The exynos5422-dmc.c can operate in both polling and IRQ mode. The user can choose the monitoring mode by using module param. The default monitoring mode is polling mode with delayed timer. 3. Add maintainer entry - Add Dmitry Osipenko <digetx@gmail.com> as maintainer for memory frequency scaling drivers for Nvidia Tegra. He have been developed and reviewed the tegra*-devfreq.c. -----BEGIN PGP SIGNATURE----- iQJKBAABCgA0FiEEsSpuqBtbWtRe4rLGnM3fLN7rz1MFAl8iiJ0WHGN3MDAuY2hv aUBzYW1zdW5nLmNvbQAKCRCczd8s3uvPU+WbD/0TkndmsnqXgzkLsyAUFgWsRy3N LL8xwtHXmM76ujT5m5UH5A+BHp3Ex9SsGA4xJ9cr7C3Reg2OmSKe8BZjkA52fwDE 2qu0CHB4IP41EjS3skBqiEhSGdFPv7xd9z39dk6xgUNaQM3yEmcrtPI96jx2CYE9 WYroUl8Lc1uU9fnV+1dyah7nK9p+pi27QqFQBdyOLikOpi2qq5loY6EsBjDq8bym Lv5VjgpI5cpBflolf1y5Zi6p+qFHNUroPz5iOnYJIUNqgKUHEhY8CdGVlLynQTo/ IOLXvhuGQc7q2grFKUjHGTAps+YV2lbY8j8WZl+ujhLTkCxme/XILHXe7b2GHHZy TleViwsdhL0lYkGCOrla66qFn2kNIXMjEnRJ3GfL7wRUFliS6IlFrg50/TLws7Qe RogI+rM/LuBPM9H4IDy5WTglChnctOxc2sSmbWKy2u1LoDMxfR/SIEwjvdFq/enx U0fE/vpXrJkADPSk/4+W/AdnnV2JmIFKlHoy83cZYzp5KHq9voQOv575sMkvSYRl hRc9Y8zxYtPOS9cJGV/nxgyEfp/gkOpcwrvy/uPuOqVMLC//ZEK/gR78nfT1YvJ3 c6ODnY8wpK+HZdqhWqc7SXWA9kK3BZrrDRkDBRPXthVOvyvKcifKn9AjVETqRGDu OPpZ19FZqIy3KMVMEg== =Iw2C -----END PGP SIGNATURE----- Merge tag 'devfreq-next-for-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux Pull devfreq updates for v5.9 from Chanwoo Choi: 1. Update devfreq core - Add delayed timer support for polling mode. Until now, devfreq supported only deferrable timer to avoid unneeded CPU wakeups. However, it has a problem for non-CPU devices, like DMC, doing DMA. Such devices need to monitor continuously regardless of the CPU state, so delayed timer support for the polling mode to facilitate the continuous monitoring. - Fix indentation of result of devfreq_summary debugfs node. - Fix the wrong end of code with a semicolon instead of a comma. - Clean-up code to use a unified local variable name in sysfs-related internal funcitons. - Fix trivial spelling mistake in devfreq-event.c. 2. Update devfreq drivers - Add the exception handling code to control when rockchip,pmu property is absent for rk3399_dmc.c. - Add missing 'rockchip,pmu' property to dt-binding document for rk3399_dmc.c. - Change the type of timer in exynos5422-dmc.c from deferrable to delayed in order to monitor the DMC (Dynamic Memory Controller) status regardless of the CPU idle state.

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.
