Device tree bindings for Low Power General Purpose Register found in i.MX6Q/D
Secure Non-Volatile Storage.

This DT node should be represented as a sub-node of a "syscon",
"simple-mfd" node.

Required properties:
- compatible: should be one of the fallowing variants:
	"fsl,imx6q-snvs-lpgpr" for Freescale i.MX6Q/D/DL/S
	"fsl,imx6ul-snvs-lpgpr" for Freescale i.MX6UL

Example:
snvs: snvs@020cc000 {
	compatible = "fsl,sec-v4.0-mon", "syscon", "simple-mfd";
	reg = <0x020cc000 0x4000>;

	snvs_lpgpr: snvs-lpgpr {
		compatible = "fsl,imx6q-snvs-lpgpr";
	};
};
