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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
