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.
Example:
Examples:
/* Legacy bindings */
thermal@d0018300 {
compatible = "marvell,armada370-thermal";
reg = <0xd0018300 0x4
reg = <0xd0018300 0x4
0xd0018304 0x4>;
};

compatible = "marvell,armada-ap806-thermal";
reg = <0x6f808C 0x4>,
<0x6f8084 0x8>;
