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. Signed-off-by:
