1 * System Controller Registers R/W driver
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
13 - compatible: Should contain "syscon".
14 - reg: the register region can be accessed from syscon
17 - reg-io-width: the size (in bytes) of the IO accesses that should be
18 performed on the device.
