1Exynos Thermal management Unit
2
3Required properties:
4
5 - compatible : Should be "samsung,exynos-tmu" for TMU
6 - samsung,min-temp : Minimum temperature value (25 degree celsius)
7	- Current temperature of SoC should be more than this value.
8 - samsung,max-temp : Maximum temperature value (125 degree celsius)
9	- Current temperature of SoC should be less than this value.
10 - samsung,start-warning : Temperature at which TMU starts giving warning (degree celsius)
11 - samsung,start-tripping : Temperature at which TMU shuts down the system (degree celsius)
12 - samsung,hw-tripping : Temperature at which hardware tripping should happen
13	in case TMU fails to power off (degree celsius)
14 - samsung,efuse-min-value : SOC efuse min value (Constant 40)
15	- efuse-value should be more than this value.
16 - samsung,efuse-value : SOC actual efuse value (Literal value)
17	- This is the data trimming info.
18	- This value is used to calculate measuring error.
19 - samsung,efuse-max-value : SoC max efuse value (Constant 100)
20	- efuse-value should be less than this value.
21 - samsung,slope : Default value 274761730 (Constant 0x1060_8802).
22	- This is the default value for TMU_CONTROL register.
23	- It sets the gain of amplifier to the positive-tc generator block.
24	- It selects thermal tripping mode and enables thermal tripping.
25 - samsung,dc-value : Measured data calibration value (Constant 25)
26	- Used for tempearture calculation.
27	- This is 25 because temperature measured is always above 25 degrees.
