1Maximum Power Mitigation Mechanism (MPMM) Bindings
2==================================================
3
4|MPMM| support cannot be determined at runtime by the firmware. Instead, these
5DTB bindings allow the platform to communicate per-core support for |MPMM| via
6the ``HW_CONFIG`` device tree blob.

17The ``cpu`` node has been augmented to allow the platform to indicate support
18for |MPMM| on a given core.

27Example
28^^^^^^^

30An example system offering two cores, one with support for |MPMM| and one
31without, can be described as follows:
32
33.. code-block::
34
35    cpus {
36        #address-cells = <2>;
37        #size-cells = <0>;
38
39        cpu0@00000 {
40            ...
41
42            supports-mpmm;
43        };
44
45        cpu1@00100 {
46            ...
47        };
48    }
