The cros-ec device tree binding only uses #pwm-cells = <1>, and so there is no period provided in the device tree. Up to now this was handled by hardcoding the period to the only supported value in the custom xlate callback. Apart from that, the default xlate callback (i.e. of_pwm_xlate_with_flags()) handles this just fine (and better, e.g. by checking args->args_count >= 1 before accessing args->args[0]). To simplify make use of of_pwm_xlate_with_flags(), drop the custom callback and provide the default period in .probe() already. Apart from simplifying the driver this also drops the last non-core user of pwm_request_from_chip() and so makes further simplifications possible.

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 reStructuredText 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.
