Subject: [PATCH v2] dt-binding: thermal: Convert marvell,armada-ap806-thermal to DT schema
Date: Fri, 22 Aug 2025 17:57:00 -0500 [thread overview]
Message-ID: <20250822225701.766947-1-robh@kernel.org> (raw)
Convert the Marvell Armada AP80x/CP110 thermal binding to schema. It is
a straight forward conversion.
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com>

v2:
- Mention the SEI connection

-Documentation/devicetree/bindings/thermal/thermal*.yaml
-
-The thermal IP can probe the temperature all around the processor. It
-may feature several channels, each of them wired to one sensor.
-
-It is possible to setup an overheat interrupt by giving at least one
-critical point to any subnode of the thermal-zone node.
-
-Required properties:
-- compatible: must be one of:
- * marvell,armada-ap806-thermal
-- reg: register range associated with the thermal functions.
-
-Optional properties:
-- interrupts: overheat interrupt handle. Should point to line 18 of the
- SEI irqchip. See interrupt-controller/interrupts.txt
-- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
- to this IP and represents the channel ID. There is one sensor per
- channel. O refers to the thermal IP internal channel, while positive
- IDs refer to each CPU.
-
-Example:
-ap_syscon1: system-controller@6f8000 {
- compatible = "syscon", "simple-mfd";
- reg = <0x6f8000 0x1000>;
