[PATCH v3 01/11] dt-bindings: thermal: Describe Armada AP806 and CP110

From: Baruch Siach <baruch@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.

Also add a note about the new property "marvell,thermal-zone-name" to
help identify the zones from the sysfs.

- 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).
+ The first one points to the status register (4B).
+ The second one points to the control registers (8B).
+ Note: with legacy bindings, the second entry pointed
+ only on the so called "control MSB" ("control 1"), was
+ 4B wide and did not let the possibility to reach the
+ "control LSB" ("control 0") register.

-Example:
+Optional properties:

+- marvell,thermal-zone-name: The name to identify the thermal zone
+ within the sysfs, useful when multiple
+ thermal zones are registered (AP, CPx...).
