1* System Controller Registers R/W driver
2
3System controller node represents a register region containing a set
4of miscellaneous registers. The registers are not cohesive enough to
5represent as any specific type of device. The typical use-case is for
6some other node's driver, or platform-specific code, to acquire a
7reference to the syscon node (e.g. by phandle, node path, or search
8using a specific compatible value), interrogate the node (or associated
9OS driver) to determine the location of the registers, and access the
10registers directly.

12Required properties:
13- compatible: Should contain "syscon".
14- reg: the register region can be accessed from syscon

16Examples:
17gpr: iomuxc-gpr@020e0000 {
18 compatible = "fsl,imx6q-iomuxc-gpr", "syscon";
19 reg = <0x020e0000 0x38>;
