[PATCH 1/3] DT Binding for omap3 temperature sensor

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";
+	};
+};
