Required properties:
- compatible: Should contain one of the following:
  - "nvidia,tegra186-pmc": for Tegra186
  - "nvidia,tegra194-pmc": for Tegra194
- reg: Must contain an (offset, length) pair of the register set for each
  entry in reg-names.
- reg-names: Must include the following entries:
  - "pmc"
  - "wake"
  - "aotag"
  - "scratch"
  - "misc" (Only for Tegra194)

Optional properties:

Example:

SoC DTSI:

	pmc@c3600000 {
		compatible = "nvidia,tegra186-pmc";
		reg = <0 0x0c360000 0 0x10000>,
		      <0 0x0c370000 0 0x10000>,
		      <0 0x0c380000 0 0x10000>,
		      <0 0x0c390000 0 0x10000>;
		reg-names = "pmc", "wake", "aotag", "scratch";
	};

Board DTS:

	pmc@c360000 {
		nvidia,invert-interrupt;
	};
