+* 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";
+ };
