"arm64: dts: ls1046a: ..." for subject prefix please.  Also, since we
have ls1046a in prefix, the 'for LS1046A' is not needed.

Unneeded newline.

Instead of a newline, can we have a single line comment here to tell how
these calibration data is grouped?

We usually do not have newline between properties but nodes, or between
property list and child node.

Have a newline here.
