Subject: [PATCH] dt-bindings: thermal: Convert brcm,sr-thermal to DT schema
Date: Mon, 13 Oct 2025 16:58:09 -0500 [thread overview]
Message-ID: <20251013215810.783006-1-robh@kernel.org> (raw)
Convert the brcm,sr-thermal binding to DT schema format. It's a
straight-forward conversion. "polling-delay", "thermal-sensors", and
"temperature" all apply to the thermal zones, not the sensor node.

-* Broadcom Stingray Thermal
-
-This binding describes thermal sensors that is part of Stingray SoCs.
-
-Required properties:
-- compatible : Must be "brcm,sr-thermal"
-- reg : Memory where tmon data will be available.
-- brcm,tmon-mask: A one cell bit mask of valid TMON sources.
- Each bit represents single TMON source.
-- #thermal-sensor-cells : Thermal sensor phandler
-- polling-delay: Max number of milliseconds to wait between polls.
-- thermal-sensors: A list of thermal sensor phandles and specifier.
- specifier value is tmon ID and it should be
- in correspond with brcm,tmon-mask.
-- temperature: trip temperature threshold in millicelsius.

-Example:
- tmons {
- compatible = "simple-bus";
- #address-cells = <1>;
