1	* Exynos Thermal Management Unit (TMU)
2	
3	** Required properties:
4	
5	- compatible : One of the following:
6		       "samsung,exynos4412-tmu"
7		       "samsung,exynos4210-tmu"
8		       "samsung,exynos5250-tmu"
9		       "samsung,exynos5440-tmu"
10	- interrupt-parent : The phandle for the interrupt controller
11	- reg : Address range of the thermal registers. For soc's which has multiple
12		instances of TMU and some registers are shared across all TMU's like
13		interrupt related then 2 set of register has to supplied. First set
14		belongs	to each instance of TMU and second set belongs to common TMU
15		registers.
16	- interrupts : Should contain interrupt for thermal system
17	- clocks : The main clock for TMU device
18	- clock-names : Thermal system clock name
19	- vtmu-supply: This entry is optional and provides the regulator node supplying
20			voltage to TMU. If needed this entry can be placed inside
21			board/platform specific dts file.
22	
23	Example 1):
24	
25		tmu@100C0000 {
26			compatible = "samsung,exynos4412-tmu";
27			interrupt-parent = <&combiner>;
28			reg = <0x100C0000 0x100>;
29			interrupts = <2 4>;
30			clocks = <&clock 383>;
31			clock-names = "tmu_apbif";
32			status = "disabled";
33			vtmu-supply = <&tmu_regulator_node>;
34		};
35	
36	Example 2):
37	
38		tmuctrl_0: tmuctrl@160118 {
39			compatible = "samsung,exynos5440-tmu";
40			reg = <0x160118 0x230>, <0x160368 0x10>;
41			interrupts = <0 58 0>;
42			clocks = <&clock 21>;
43			clock-names = "tmu_apbif";
44		};
45	
46	Note: For multi-instance tmu each instance should have an alias correctly
47	numbered in "aliases" node.
48	
49	Example:
50	
51	aliases {
52		tmuctrl0 = &tmuctrl_0;
53		tmuctrl1 = &tmuctrl_1;
54		tmuctrl2 = &tmuctrl_2;
55	};
