It is required to know the PWM clock source frequency to calculate the PWM period. In driver, the clock source frequency of the PWM does not get change and, hence, get the clock source frequency in driver init. Get this values later for period calculation from pwm_config(). This will help in avoiding the clock call for getting clock rate in the pwm_config() each time.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
