Joakim Zhang 0a2228ab23 MLK-23195-3 perf/imx_ddr: speed up overflow frequency of cycle counter
For i.MX8MP, we cannot ensure that cycle counter overflow occurs at
least 4 times as often as other events. Due to byte counters will count for
any event configured, it will overflow more often. And if byte counters
oveflow that related counters would stop since they share the
COUNTER_CNTL. We can speed up cycle counter overflow frequency by
setting counter parameter(CP) field of cycle counter.

README

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.
