Binding for the HSDK v1 reset controller



This binding uses the common reset binding[1].



[1] Documentation/devicetree/bindings/reset/reset.txt



Required properties:

- compatible: should be "snps,hsdk-v1.0-reset".

- reg: should always contain 2 pairs address - length: first for reset

  configuration register and second for corresponding SW reset and status bits

  register.

- #reset-cells: from common reset binding; Should always be set to 1.



Example:

	reset: reset@880 {

		compatible = "snps,hsdk-v1.0-reset";

		#reset-cells = <1>;

		reg = <0x8A0 0x4>, <0xFF0 0x4>;

	};



Specifying reset lines connected to IP modules:

	ethernet@.... {

		....

		resets = <&reset HSDK_V1_ETH_RESET>;

		....

	};
