OMAP34xx and OMAP36xx processors contain a register in the syscon area,
which can be used to determine the SoCs temperature. This provides a
DT binding specification for the temperature monitor.

+* OMAP3 temperature sensor
+
+The OMAP34xx and OMAP36xx processors contain a register in the syscon area,
+which can be used to determine the SoCs temperature.
+
+Requires node properties:
+- compatible : should contain one of
+ - "ti,omap34xx-temperature-sensor" for OMAP34xx
+ - "ti,omap36xx-temperature-sensor" for OMAP36xx
+- syscon : Should be a phandle to system configuration node which
+ encompases the temperature register
+- clocks : Should contain 32KHz fclk clock specifier
+- clock-names : Should contain clock names
+ - "fck" for the 32KHz fclk clock specifier
+
+Example for omap34xx:
+
+/ {
+ temperature-sensor {
+ compatible = "ti,omap34xx-temperature-sensor";
+ syscon = <&omap3_scm_general>;
+ clocks = <&ts_fck>;
+ clock-names = "fck";
+ };
+};
