- * 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;
- };
