| * System Controller Registers R/W driver | |
| System controller node represents a register region containing a set | |
| of miscellaneous registers. The registers are not cohesive enough to | |
| represent as any specific type of device. The typical use-case is for | |
| some other node's driver, or platform-specific code, to acquire a | |
| reference to the syscon node (e.g. by phandle, node path, or search | |
| using a specific compatible value), interrogate the node (or associated | |
| OS driver) to determine the location of the registers, and access the | |
| registers directly. | |
| Required properties: | |
| - compatible: Should contain "syscon". | |
| - reg: the register region can be accessed from syscon | |
| Optional property: | |
| - reg-io-width: the size (in bytes) of the IO accesses that should be | |
| performed on the device. | |
| Examples: | |
| gpr: iomuxc-gpr@020e0000 { | |
| compatible = "fsl,imx6q-iomuxc-gpr", "syscon"; | |
| reg = <0x020e0000 0x38>; | |
| }; |
