* clk: pwm: Migrate to clk_hw based OF and registration APIsStephen Boyd2016-08-241-5/+4
| | | | | | | | | | | | Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.

* clk: pwm: Use pwm_get_args() where appropriateBoris Brezillon2016-05-171-5/+12
| | | | | | | | | | | | | | | | | The PWM framework has clarified the concept of reference PWM config (the platform dependent config retrieved from the DT or the PWM lookup table) and real PWM state. Use pwm_get_args() when the PWM user wants to retrieve this reference config and not the current state. This is part of the rework allowing the PWM framework to support hardware readout and expose real PWM state even when the PWM has just been requested (before the user calls pwm_config/enable/disable()).

* clk: Add PWM clock driverPhilipp Zabel2015-04-101-0/+136
Some board designers, when running out of clock output pads, decide to (mis)use PWM output pads to provide a clock to external components. This driver supports this practice by providing an adapter between the PWM and clock bindings in the device tree. As the PWM bindings specify the period in the device tree, this is a fixed clock.
