Wysocki Make the imx_thermal driver use the .should_bind() thermal zone callback to provide the thermal core with the information on whether or not to bind the given cooling device to the given trip point in the given thermal zone. If it returns 'true', the thermal core will bind the cooling device to the trip and the corresponding unbinding will be taken care of automatically by the core on the removal of the involved thermal zone or cooling device. In the imx_thermal case, it only needs to return 'true' for the passive trip point and it will match any cooling device passed to it, in analogy with the old-style imx_bind() callback function.
