+title: TI-SCI reset controller
+

+  - Nishanth Menon <nm@ti.com>
+
+description: |
+  Some TI SoCs contain a system controller (like the Power Management Micro
+  Controller (PMMC) on Keystone 66AK2G SoC) that are responsible for controlling
+  the state of the various hardware modules present on the SoC. Communication
+  between the host processor running an OS and the system controller happens
+  through a protocol called TI System Control Interface (TI-SCI protocol).
+
+  This reset controller node uses the TI SCI protocol to perform the reset
+  management of various hardware modules present on the SoC. Must be a child
+  node of the associated TI-SCI system controller node.
+
+properties:
+  $nodename:
+    pattern: "^reset-controller$"
+
+  compatible:
+    const: ti,sci-reset
+
+  "#reset-cells":
+    const: 2
+    description:
+      The two cells represent values that the TI-SCI controller defines.
+
+      The first cell should contain the device ID.
+
+      The second cell should contain the reset mask corresponding to the device
+      used by system controller.
+
+      Please see  http://processors.wiki.ti.com/index.php/TISCI for
+      protocol documentation for the values to be used for different devices.
