Subject[PATCH 1/2] dt-bindings: documentation: add clock bindings information for Agilex
Date
From: Dinh Nguyen <dinh.nguyen@intel.com>

Document the Agilex clock bindings, and add the clock header file. The
clock header is an enumeration of all the different clocks on the Agilex
platform.

+Device Tree Clock bindings for Intel's SoCFPGA Agilex platform
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be
+ "intel,agilex-clkmgr"
+
+- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
+
+- #clock-cells : from common clock binding, shall be set to 1.
+
+Example:
+ clkmgr: clock-controller@ffd10000 {
+ compatible = "intel,agilex-clkmgr";
+ reg = <0xffd10000 0x1000>;
+ #clock-cells = <1>;
+ };
