  1. * Dialog DA9055 Power Management Integrated Circuit (PMIC)
    2. 

  2. 

  3. DA9055 consists of a large and varied group of sub-devices (I2C Only):
    4. 

  4. 

  5. Device			 Supply Names	 Description
    6. 

  6. ------			 ------------	 -----------
    7. 

  7. da9055-gpio		:		: GPIOs
    8. 

  8. da9055-regulator	:		: Regulators
    9. 

  9. da9055-onkey		:		: On key
    10. 

  10. da9055-rtc		:		: RTC
    11. 

  11. da9055-hwmon		:		: ADC
    12. 

  12. da9055-watchdog		:		: Watchdog
    13. 

  13. 

  14. The CODEC device in DA9055 has a separate, configurable I2C address and so
    15. 

  15. is instantiated separately from the PMIC.
    16. 

  16. 

  17. For details on accompanying CODEC I2C device, see the following:

  20. ======
    21. 

  21. 

  22. Required properties:
    23. 

  23. - compatible : Should be "dlg,da9055-pmic"
    24. 

  24. - reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
    25. 

  25. - interrupt-parent: Specifies the phandle of the interrupt controller to which
    26. 

  26.   the IRQs from da9055 are delivered to.
    27. 

  27. - interrupts: IRQ line info for da9055 chip.
    28. 

  28. - interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
    29. 

  29. - #interrupt-cells: Should be 1, is the local IRQ number for da9055.
    30. 

  30. 

  31. Sub-nodes:
    32. 

  32. - regulators : Contain the regulator nodes. The DA9055 regulators are
    33. 

  33.   bound using their names as listed below:
    34. 

  34. 

  35.     buck1     : regulator BUCK1
    36. 

  36.     buck2     : regulator BUCK2
    37. 

  37.     ldo1      : regulator LDO1
    38. 

  38.     ldo2      : regulator LDO2
    39. 

  39.     ldo3      : regulator LDO3
    40. 

  40.     ldo4      : regulator LDO4
    41. 

  41.     ldo5      : regulator LDO5
    42. 

  42.     ldo6      : regulator LDO6
    43. 

  43. 

  44.   The bindings details of individual regulator device can be found in:
    45.

  48. Example:
    49. 

  49. 

  50. 	pmic: da9055-pmic@5a {
    51. 

  51. 		compatible = "dlg,da9055-pmic";

  52. 		reg = <0x5a>;
    53. 

  53. 		interrupt-parent = <&intc>;
    54. 

  54. 		interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
    55. 

  55. 		interrupt-controller;
    56. 

  56. 		#interrupt-cells = <1>;
    57. 

  57. 

  58. 		regulators {
    59. 

  59. 			buck1: BUCK1 {
    60. 

  60. 				regulator-min-microvolt = <725000>;

  61. 				regulator-max-microvolt = <2075000>;
    62. 

  62. 			};
    63. 

  63. 			buck2: BUCK2 {

  64. 				regulator-min-microvolt = <925000>;
    65. 

  65. 				regulator-max-microvolt = <2500000>;
    66.
