Probably the following form?

	/* Calibration data group 1 */
	...
	/* Calibration data group 2 */
	...
	/* Calibration data group 3 */
	...
	/* Calibration data group 4 */
	...

Different subsystem or binding examples use different style, but when we
put things together in the platform dts, we would like to have them in a
unified style.
