[PATCH v7 01/11] dt-bindings: thermal: Describe Armada AP806 and CP110

[Miquel Raynal]

From: Baruch Siach <baruch at tkos.co.il>

Add compatible strings for AP806 and CP110 that are part of the Armada
8k/7k line of SoCs.

Add a note on the differences in the size of the control area in
different bindings. This is an existing difference between the Armada
375 binding and the other boards already supported. The new AP806 and
CP110 bindings are similar to the existing Armada 375 in this regard.

 Required properties:
 
-- compatible:	Should be set to one of the following:
-		marvell,armada370-thermal
-		marvell,armada375-thermal
-		marvell,armada380-thermal
-		marvell,armadaxp-thermal
+- compatible: Should be set to one of the following:
+    * marvell,armada370-thermal
+    * marvell,armada375-thermal
+    * marvell,armada380-thermal
+    * marvell,armadaxp-thermal
+    * marvell,armada-ap806-thermal
+    * marvell,armada-cp110-thermal
 
-- reg:		Device's register space.
-		Two entries are expected, see the examples below.
-		The first one is required for the sensor register;
-		the second one is required for the control register
-		to be used for sensor initialization (a.k.a. calibration).
+- reg: Device's register space.
+  Two entries are expected, see the examples below. The first one points
+  to the status register (4B). The second one points to the control
+  registers (8B).
+  Note: The compatibles marvell,armada370-thermal,
+  marvell,armada380-thermal, and marvell,armadaxp-thermal must point to
+  "control MSB/control 1", with size of 4 (deprecated binding), or point
+  to "control LSB/control 0" with size of 8 (current binding). All other
+  compatibles must point to "control LSB/control 0" with size of 8.
