This allows to simplify all drivers that use three pwm-cells. The only ugly side effect is that if a driver specified of_pwm_n_cells = 2 it suddenly supports device trees that use #pwm-cells = <3>. This however isn't a bad thing because the driver doesn't need explicit support for three cells as the core handles all the details. Also there is no such in-tree driver.

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.
