dt-bindings: microchip: atmel,at91rm9200-tcb: Add atmel,tcb-pwm 



Move the TCB pwm nodes under their parent. This removes the need for the
tc-block property as there is now a child-parent relationship between the
TC channel and the TC block.

Move the documentation to the main file.

Atmel TCB PWM controller



Required properties:

- compatible: should be "atmel,tcb-pwm"

- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of

  the cells format. The only third cell flag supported by this binding is

  PWM_POLARITY_INVERTED.

- tc-block: The Timer Counter block to use as a PWM chip.



Example:



pwm {

	compatible = "atmel,tcb-pwm";

	#pwm-cells = <3>;

	tc-block = <1>;

};
