Hi Scott,

Eduardo indicated that "calibration" property should add "fsl" prefix.
I updated the patch.
Any other comments?
If not I will send V3 soon.

Thanks.

+* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs
+
+Required properties:
+- compatible : Must include "fsl,qoriq-tmu". The version of the device
is
+	determined by the TMU IP Block Revision Register (IPBRR0) at
+	offset 0x0BF8.
+	Table of correspondences between IPBRR0 values and example  chips:
+		Value           Device
+		----------      -----
+		0x01900102      T1040
+- reg : Address range of TMU registers.
+- interrupts : Contains the interrupt for TMU.
+- calibration : Calibration table for TMU. This is required to determine
+	what a specific sensor reading translates to in degrees Celsius.
+	There are four calibration config ranges, for each range we need
+	a couple of calibration data formatted like <TTCFGR, TSCFGR>.
+	Freescale provides the data required.
+
+Example:
+
+tmu@f0000 {
+	compatible = "fsl,qoriq-tmu";
+	reg = <0xf0000 0x1000>;
+	interrupts = <18 2 0 0>;
