The cooling device should be part of the i.MX cpufreq driver, but it
cannot be removed for the sake of DT stability. So turn the cooling
device registration into a separate function and perform the
registration only if the CPU OF node does not have the #cooling-cells
property.
Use of_cpufreq_power_cooling_register in imx_thermal code to link the
cooling device to the device tree node provided.
This makes it possible to bind the cpufreq cooling device to a custom
thermal zone via a cooling-maps entry like:
cooling-maps {
map0 {
trip = <&board_alert>;
cooling-device = <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
};
};
Assuming a cpu node exists with label "cpu0" and #cooling-cells
property.
