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 };
