1	* System Controller Registers R/W driver
2	
3	System controller node represents a register region containing a set
4	of miscellaneous registers. The registers are not cohesive enough to
5	represent as any specific type of device. The typical use-case is for
6	some other node's driver, or platform-specific code, to acquire a
7	reference to the syscon node (e.g. by phandle, node path, or search
8	using a specific compatible value), interrogate the node (or associated
9	OS driver) to determine the location of the registers, and access the
10	registers directly.
11	
12	Required properties:
13	- compatible: Should contain "syscon".
14	- reg: the register region can be accessed from syscon
15	
16	Examples:
17	gpr: iomuxc-gpr@020e0000 {
18		compatible = "fsl,imx6q-iomuxc-gpr", "syscon";
19		reg = <0x020e0000 0x38>;
20	};
