Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.

Hi Rob,

Thank you for the note. I will take care from next time onward.

Thanks & Regards,
Srinath.

+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>;
+
+		tmon: tmon@0 {
