+Required properties:

+
+Optional properties:
+
+  - marvell,caldata* : A series of properties with marvell,caldata prefix,
+  		      represent Calibration data downloaded to the device during
+		      initialization. This is an array of unsigned values.

+Example:
+
+Tx power limit calibration data is configured in below example.
+The calibration data is an array of unsigned values, the length
+can vary between hw versions.
