The first cell is the pin number and the 41 second cell is used to specify the gpio polarity. 42 43See Documentation/devicetree/bindings/gpio/gpio.txt for further information on 44GPIO bindings. 45 46- interrupts : IRQ line information. 47- interrupt-controller 48 49See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for 50further information on IRQ bindings. 51 52Sub-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 93Example: 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>; 110 regulator-max-microvolt = <1570000>; 111 regulator-min-microamp = <500000>; 112 regulator-max-microamp = <2000000>; 113 regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>; 114 regulator-boot-on; 115 }; 116 DA9062_LDO1: ldo1 { 117 regulator-name = "LDO_1"; 118 regulator-min-microvolt = <900000>; 119 regulator-max-microvolt = <3600000>; 120 regulator-boot-on; 121 }; 122 }; 123 }; 124 125
