Boris Brezillon	dd0b38b7ca	clk: pwm: Use pwm_get_args() where appropriate ... 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()).

Philipp Zabel	9a74ccdbbb	clk: Add PWM clock driver ... 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.
