| 27 | ====== |
| 28 | |
| 29 | Required properties: |
| 30 | |
| 31 | - compatible : Should be |
| 32 | "dlg,da9062" for DA9062 |
| 33 | "dlg,da9061" for DA9061 |
| 34 | - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be |
| 35 | modified to match the chip's OTP settings). |
| 36 | |
| 37 | Optional properties: |
| 38 | |
| 39 | - gpio-controller : Marks the device as a gpio controller. |
| 40 | - #gpio-cells : Should be two. The first cell is the pin number and the |
| 41 | second cell is used to specify the gpio polarity. |
| 42 | |
| 43 | See Documentation/devicetree/bindings/gpio/gpio.txt for further information on |
| 44 | GPIO bindings. |
| 45 | |
| 46 | - interrupts : IRQ line information. |
| 47 | - interrupt-controller |
| 48 | |
| 49 | See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for |
| 50 | further information on IRQ bindings. |
| 51 | |
| 52 | Sub-nodes: |
| 53 | |
| 54 | - regulators : This node defines the settings for the LDOs and BUCKs. |
| 55 | The DA9062 regulators are bound using their names listed below: |
| 56 | |
| 57 | buck1 : BUCK_1 |
| 58 | buck2 : BUCK_2 |
| 59 | buck3 : BUCK_3 |
| 60 | buck4 : BUCK_4 |
| 61 | ldo1 : LDO_1 |
| 62 | ldo2 : LDO_2 |
| 63 | ldo3 : LDO_3 |
| 64 | ldo4 : LDO_4 |
| 65 | |
| 66 | The DA9061 regulators are bound using their names listed below: |
| 67 | |
| 68 | buck1 : BUCK_1 |
| 69 | buck2 : BUCK_2 |
| 70 | buck3 : BUCK_3 |
| 71 | ldo1 : LDO_1 |
| 72 | ldo2 : LDO_2 |
| 73 | ldo3 : LDO_3 |
| 74 | ldo4 : LDO_4 |
| 75 | |
| 76 | The component follows the standard regulator framework and the bindings |
| 77 | details of individual regulator device can be found in: |
| 78 | Documentation/devicetree/bindings/regulator/regulator.txt |
| 79 | |
| 80 | regulator-initial-mode may be specified for buck regulators using mode values |
| 81 | from include/dt-bindings/regulator/dlg,da9063-regulator.h. |
| 82 | |
| 83 | - rtc : This node defines settings required for the Real-Time Clock associated |
| 84 | with the DA9062. There are currently no entries in this binding, however |
| 85 | compatible = "dlg,da9062-rtc" should be added if a node is created. |
| 86 | |
| 87 | - onkey : See ../input/da9062-onkey.txt |
| 88 | |
| 89 | - watchdog: See ../watchdog/da9062-wdt.txt |
| 90 | |
| 91 | - thermal : See ../thermal/da9062-thermal.txt |
| 92 | |
| 93 | Example: |
| 94 | |
| 95 | pmic0: da9062@58 { |
| 96 | compatible = "dlg,da9062"; |
| 97 | reg = <0x58>; |
| 98 | interrupt-parent = <&gpio6>; |
| 99 | interrupts = <11 IRQ_TYPE_LEVEL_LOW>; |
| 100 | interrupt-controller; |
| 101 | |
| 102 | rtc { |
| 103 | compatible = "dlg,da9062-rtc"; |
| 104 | }; |
| 105 | |
| 106 | regulators { |
| 107 | DA9062_BUCK1: buck1 { |
| 108 | regulator-name = "BUCK1"; |
| 109 | regulator-min-microvolt = <300000>; |

| 112 | regulator-max-microamp = <2000000>; |
| 113 | regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>; |
| 114 | regulator-boot-on; |
| 115 | }; |
| 116 | DA9062_LDO1: ldo1 { |
