Maximum Power Mitigation Mechanism (MPMM) Bindings
==================================================
|MPMM| support cannot be determined at runtime by the firmware. Instead, these
DTB bindings allow the platform to communicate per-core support for |MPMM| via
the ``HW_CONFIG`` device tree blob.
Bindings
^^^^^^^^
.. contents::
:local:
``/cpus/cpus/cpu*`` node properties
"""""""""""""""""""""""""""""""""""
The ``cpu`` node has been augmented to allow the platform to indicate support
for |MPMM| on a given core.
+-------------------+-------+-------------+------------------------------------+
| Property name | Usage | Value type | Description |
+===================+=======+=============+====================================+
| ``supports-mpmm`` | O | ``<empty>`` | If present, indicates that |MPMM| |
| | | | is available on this core. |
+-------------------+-------+-------------+------------------------------------+
Example
^^^^^^^
An example system offering two cores, one with support for |MPMM| and one
without, can be described as follows:
.. code-block::
cpus {
#address-cells = <2>;
#size-cells = <0>;
cpu0@00000 {
...
supports-mpmm;
};
cpu1@00100 {
...
};
}
