* Exynos Thermal Management Unit (TMU)
** Required properties:
- compatible : One of the following:
"samsung,exynos4412-tmu"
"samsung,exynos4210-tmu"
"samsung,exynos5250-tmu"
"samsung,exynos5440-tmu"
- interrupt-parent : The phandle for the interrupt controller
- reg : Address range of the thermal registers. For soc's which has multiple
instances of TMU and some registers are shared across all TMU's like
interrupt related then 2 set of register has to supplied. First set
belongs to each instance of TMU and second set belongs to common TMU
registers.
- interrupts : Should contain interrupt for thermal system
- clocks : The main clock for TMU device
- clock-names : Thermal system clock name
- vtmu-supply: This entry is optional and provides the regulator node supplying
voltage to TMU. If needed this entry can be placed inside
board/platform specific dts file.
Example 1):
tmu@100C0000 {
compatible = "samsung,exynos4412-tmu";
interrupt-parent = <&combiner>;
reg = <0x100C0000 0x100>;
interrupts = <2 4>;
clocks = <&clock 383>;
clock-names = "tmu_apbif";
status = "disabled";
vtmu-supply = <&tmu_regulator_node>;
};
Example 2):
tmuctrl_0: tmuctrl@160118 {
compatible = "samsung,exynos5440-tmu";
reg = <0x160118 0x230>, <0x160368 0x10>;
interrupts = <0 58 0>;
clocks = <&clock 21>;
clock-names = "tmu_apbif";
};
Note: For multi-instance tmu each instance should have an alias correctly
numbered in "aliases" node.
Example:
aliases {
tmuctrl0 = &tmuctrl_0;
tmuctrl1 = &tmuctrl_1;
tmuctrl2 = &tmuctrl_2;
};
