Required properties:
- #cooling-cells: Used to provide cooling device specific information
Type: unsigned while referring to it. Must be at least 2, in order
- Size: one cell to specify minimum and maximum cooling state used
+ Size: one cell to specify minimum and maximum cooling state used
in the reference. The first cell is the minimum
cooling state requested and the second cell is
the maximum cooling state requested in the reference.
Optional property:
- contribution: The cooling contribution to the thermal zone of the
Type: unsigned referred cooling device at the referred trip point.
- Size: one cell The contribution is a ratio of the sum
+ Size: one cell The contribution is a ratio of the sum
of all cooling contributions within a thermal zone.
Note: Using the THERMAL_NO_LIMIT (-1UL) constant in the cooling-device phandle
Size: one cell
- thermal-sensors: A list of thermal sensor phandles and sensor specifier
- Type: list of used while monitoring the thermal zone.
