+title: TI-SCI clock controller
+
+maintainers:
+ - 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 clock controller node uses the TI SCI protocol to perform various clock
+ management of various hardware modules (devices) present on the SoC. This
+ node must be a child node of the associated TI-SCI system controller node.
+
+properties:
+ $nodename:
+ pattern: "^clock-controller$"
+
+ compatible:
+ const: ti,k2g-sci-clk
+
+ "#clock-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 clock ID.
+
+ Please see http://processors.wiki.ti.com/index.php/TISCI for
+ protocol documentation for the values to be used for different devices.
