[PATCH V3 1/4] dt-bindings: Add Broadcom AVS RO thermal
From: Stefan Wahren <wahrenst@gmx.net>
Date: 2020-01-07 18:16:22
Also in:
linux-devicetree, linux-pm
Subsystem:
open firmware and flattened device tree bindings, the rest, thermal · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds, Rafael J. Wysocki, Daniel Lezcano
Since the BCM2711 doesn't have a AVS TMON block, the thermal information must be retrieved from the AVS ring oscillator block. This block is part of the AVS monitor which contains a bunch of raw sensors.
