+description: |
+  The i.MX8ulp SIM (System Integration Module) may contain reset controller to
+  reset peripherals. The reset controller is controlled by the SIM. So, the
+  reset controller's device node has to be a child node of the SIM's device
+  node. Peripherals that need access to reset lines should specify them as a
+  reset phandle in their corresponding device nodes as specified in reset.txt.
