[PATCH 2/9] dt-bindings: soc: google: Add Google Tensor CPM binding
From: Brian Norris
Date: Mon Oct 26 2026 - 17:45:56 EST
The Central Power Manager (CPM) is a co-processor on the Google Tensor
SoCs, as used on Pixel phones. CPM supports power-management and a
number of other features.
The Application Processor communicates with CPM over a pair of mailbox
channels. CPM provides clock, power-domain, reset, and interrupt
services.
Notably, CPM manages other services that are not yet included in this
binding -- some attached PMICs, an RTC, and more. For simplicity, we
don't try to describe and support all features all at once.
Because it may be useful both for reviewers familiar with the downstream
Linux support for these devices, or for future developers looking at
adapting/improving/adding further features later on, it's worth noting
some major deviations from downstream bindings:
* CPM does not sit on the soc bus, and does not have any IO/reg region
of its own. The downstream bindings included some not-quite-related
hardware resources in the same "device", to aid doing some similar
things in the same driver. For instance, some power domains
(specifically, the GPU) are not managed by CPM, and instead are left
for direct-register-access. Such a domain should be described
separately, and not within the CPM node.
* Downstream bindings tended to describe every CPM-using service as its
own node, with a (fake) mailbox-phandle back to the CPM node. We try
as much as possible here to avoid separate nodes if we can help it.
And see the next point:
* Downstream bindings tended to describe every individual clock, reset,
and power-domain as their own sub-node, with various
software-describing properties as part of each node. These properties
are inherent to the SoC, however, so we avoid sub-nodes and instead
just provide appropriate #{clock,power-domain,reset}-cells, and leave
the per-{power-domain,clock} properties to the driver.

+description: |
+ The Central Power Manager (CPM) is an on-chip power management subsystem
+ found on Google Tensor SoCs. It has a variety of responsibilities, from DVFS
+ and power management to resets, PMIC control, and even RTC management. The
+ Application Processor communicates with CPM over a set of mailbox channels.
