 Required properties:

                 marvell,armada370-thermal

                 marvell,armadaxp-thermal
 
+                Note: As the name suggests, "marvell,armada375-z1-thermal"
+                applies for the SoC Z1 stepping only. On such stepping
+                some quirks need to be done and the register offset differs
+                from the one in the A0 stepping.
+                The operating system may auto-detect the SoC stepping and
+                update the compatible and register offsets at runtime.
+
 - reg:          Device's register space.
                 Two entries are expected, see the examples below.
                 The first one is required for the sensor register;
