* General Power Controller (GPC)
-------------------------------------------
The General Power Controller (GPC) module controls the following functions:
  - Provide low power mode control for A7 and M4 platform
  - Provide Power domain management all ARM and SOC power domain
  - Provide domain control mechanism based on A7 and M4 CPU domain
  - Provide handshake with CCM for clock management in low power mode
  - Provide handshake with SRC for power down and power up sequence
  - Provide handshake with Analog for Deep Sleep Mode control

Required properties:
  - reg : Offset and length of the register set of the GPC block.
  - compatible : Must contain a chip-specific GPC block compatible string
	and (if applicable) may contain a chassis-version GPC compatible
	string. Chip-specific strings are of the form "fsl,<chip>-gpc",
	such as:
	* "fsl,imx7d-gpc"
	* "fsl,imx7s-gpc"
  - interrupt-controller : Specifies that this is an interrupt controller

Example:
The GPC node for imx7d:
	gpc: gpc@303a0000 {
		compatible = "fsl,imx7d-gpc";
		reg = <0x303a0000 0x1000>;
		interrupt-controller;
		interrupts = <GIC_SPI 87 IRQ_TYPE_LEVEL_HIGH>;
		#interrupt-cells = <3>;
		interrupt-parent = <&intc>;
		fsl,mf-mix-wakeup-irq = <0x54010000 0xc00 0x0 0x1040640>;
	};

* Power Gating Controller (PGC)
-------------------------------------------
The Power Gating Controller (PGC) is a power management component that controls the
power-down and power-up sequencing of individual subsystems.
The PGC block is found inside GPC, and share the same register.

Required properties:
  - compatible : Must contain a chip-specific PGC block compatible string
	and (if applicable) may contain a chassis-version PGC compatible
	string. Chip-specific strings are of the form "fsl,<chip>-pgc",
	such as:
	* "fsl,imx7d-pgc"
	* "fsl,imx7s-pgc"
  - *-supply : Specifies the regulators that can be managed by this PGC. For exampe:
	* "mipi-phy-supply = <&reg_1p0d>;"

Example:
The PGC node for imx7d:
	pgc {
		compatible = "fsl,imx7d-pgc";
		mipi-phy-supply = <&reg_1p0d>;
		pcie-phy-supply = <&reg_1p0d>;
		vcc-supply = <&reg_1p2>;
	};
