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