Sascha Hauer bbe7cbd074 PM / devfreq: rockchip-dfi: account for multiple DDRMON_CTRL registers
The currently supported RK3399 has a set of registers per channel, but
it has only a single DDRMON_CTRL register. With upcoming RK3588 this
will be different, the RK3588 has a DDRMON_CTRL register per channel.

Instead of expecting a single DDRMON_CTRL register, loop over the
channels and write the channel specific DDRMON_CTRL register. Break
out early out of the loop when there is only a single DDRMON_CTRL
register like on the RK3399.

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.
