| * 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 |
| |
| Examples: |
| gpr: iomuxc-gpr@020e0000 { |
| compatible = "fsl,imx6q-iomuxc-gpr", "syscon"; |
| reg = <0x020e0000 0x38>; |
| }; |
