description: |
The System Integration Module (SIM) provides system control and chip
configuration registers. One typical use-case is for some other nodes to
acquire a reference to the syscon node by phandle, and the other typical
use-case is that the operating system should consider all subnodes of the
SIM module as separate child devices.
