mainlining shenanigans

DMC-620 PMU supports total 10 counters which each is independently programmable to different events and can be started and stopped individually. Currently, it only supports ACPI. Other platforms feel free to test and add support for device tree. Usage example: #perf stat -e arm_dmc620_10008c000/clk_cycle_count/ -C 0 Get perf event for clk_cycle_count counter. #perf stat -e arm_dmc620_10008c000/clkdiv2_allocate,mask=0x1f,match=0x2f, incr=2,invert=1/ -C 0 The above example shows how to specify mask, match, incr, invert parameters for clkdiv2_allocate event.

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.
