OK, I see. I will add only 'compatible' and skip the rest then.
So the lpddr3.txt file will get this addition:

+Samsung K3QF2F20DB LPDDR3 memory
+------------------------------------------------------------
+
+This binding uses the LPDDR3 binding (described above)
+
+Required properties:
+- compatible: Should be:
+ "samsung,K3QF2F20DB"
+ followed by "jedec,lpddr3"
+
+Optional properties:
+
+The optional properties are the same as in the LPDDR3 generic bindings and
+values should be taken from the data-sheet. Detailed bindings are described
+above.
+
+Child nodes:
+
+Detailed bindings are described in LPDDR3 generic bindings described above.
+

Is it OK?

Regards,
Lukasz
