+title: NXP i.MX8ULP System Integration Module Reset Controller

+
+description: |
+  Some instances of i.MX8ULP's SIM may offer control over the
+  reset of some components of a certain domain (e.g: AVD-SIM).
+  As far as the DT is concerned, this means that the reset
+  controller needs to be a child of the SIM node.
+
+properties:
+  compatible:
+    const: nxp,imx8ulp-avd-sim-reset
+
+  '#reset-cells':
+    const: 1
+
+required:
+  - compatible
+  - '#reset-cells'
+
+additionalProperties: false
+
+examples:
+  - |
+    #include <dt-bindings/clock/imx8ulp-clock.h>
+    syscon@2da50000 {
+      compatible = "nxp,imx8ulp-avd-sim", "syscon";
+      reg = <0x2da50000 0x38>;
+      clocks = <&pcc5 IMX8ULP_CLK_AVD_SIM>;
+
+      reset-controller {
+        compatible = "nxp,imx8ulp-avd-sim-reset";
+        #reset-cells = <1>;
+      };
