+btmrvl
+------
+
+Required properties:
+
+  - compatible : must be "btmrvl,cfgdata"
+
+Optional properties:
+
+  - btmrvl,cal-data : Calibration data downloaded to the device during
+                     initialization. This is an array of 28 values(u8).
+
+  - btmrvl,gpio-gap : gpio and gap (in msecs) combination to be
+                     configured.
+
+Example:
+
+GPIO pin 13 is configured as a wakeup source and GAP is set to 100 msecs
+in below example.
