* pwm: Add the pwm_is_enabled() helperBoris Brezillon2015-07-201-2/+2
| | | | | | | | | | Some PWM drivers are testing the PWMF_ENABLED flag. Create a helper function to hide the logic behind enabled test. This will allow us to smoothly move from the current approach to an atomic PWM update approach.

* pwm: add ep93xx PWM supportH Hartley Sweeten2013-10-171-0/+230
Remove the non-standard EP93xx PWM driver in drivers/misc and add a new driver for the PWM controllers on the EP93xx platform based on the PWM framework. These PWM controllers each support 1 PWM channel with programmable duty cycle, frequency, and polarity inversion.
