Subject: [PATCH 17/27] dt-bindings: ap806: add the thermal node in the syscon file
Date: Sat, 21 Apr 2018 17:12:45 +0200 [thread overview]
Message-ID: <20180421151255.29929-18-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20180421151255.29929-1-miquel.raynal@bootlin.com>
Explain the thermal bindings now that the thermal IP is described being
inside of a system controller. Add a reference to the thermal-zone node.

+Thermal:
+--------
+
+For common binding part and usage, refer to
+Documentation/devicetree/bindings/thermal/thermal.txt
+
+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: "marvell,armada-ap806-thermal"
+
+Optional properties:
+- interrupt-parent/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>;
+
+ ap_thermal: ap-thermal {
+ compatible = "marvell,armada-ap806-thermal";
+ interrupt-parent = <&sei>;
+ interrupts = <18>;
+ #thermal-sensor-cells = <1>;
+ };
