* Thermal Monitoring Unit (TMU) on Freescale i.MX8MM SoC

Required properties:
- compatible : Must be one of the following:
  - "fsl,imx8mm-tmu",
  - "fsl,imx8mp-tmu".
- reg : Address range of TMU registers.
- clocks : TMU's clock source.
- #thermal-sensor-cells : Should be 1 for SoC that supports multi-site sensor,
  otherwise, should be 0. See ./thermal.txt for a description.

Example:
tmu: tmu@30260000 {
	compatible = "fsl,imx8mm-tmu";
	reg = <0x30260000 0x10000>;
	clocks = <&clk IMX8MM_CLK_TMU_ROOT>;
	#thermal-sensor-cells = <0>;
};
