+* Meta Control Logic Device(CLD) Driver
+
+PROPERTIES
+
+- compatible:
+  Usage:      required
+  Type:       <string-list>
+  Definition: must include "meta,control-logic-device-<driver version>."
+              For v1, the register number, name and mode can be set in dts file.
+              Driver exports the filesystem following the dts setting.
+
+- reg:
+  Usage:      required
+  Definition: physical address
+
+- register-map:
+	Usage:      optional
+	type:       <string-list>
+	Definition: this property is an array of strings defining the names, modes
+		    and offsets of the CLD registers. The string format is "<name>:<mode>:<offset>".
+		<name>: the system file name
+		<mode>: the system file access mode. Should be r, w or rw.
+		<offset>: the register offset. If it begins with 0x the number will be
+			  parsed as a hexadecimal, if it otherwise begins with 0, it will
+			  be parsed as an octal number. Otherwise it will be parsed as a
+			  decimal.
+
+EXAMPLE
+	cld: cld@0f {
+		compatible = "meta,control-logic-device-v1";
+		reg = <0x0f>;
+		registers-map =
+			"uart-selection:rw:0x00",
+			"led-identify:rw:0x01",
+			"led-critical:rw:0x02";
+	};

Subject: drop second/last, redundant "bindings". The "dt-bindings"
prefix is already stating that these are bindings.

Subject: Drop "driver"

New bindings only in DT schema format. Start
Documentation/devicetree/bindings/writing-schema.rst,
example-schema.yaml and other docs.
