+* 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>;
+ #size-cells = <1>;
+ ranges = <0x0 0x0 0x8f100000 0x100>;
