The first cell is the pin number and the 46 second cell is used to specify the gpio polarity. 47 48See Documentation/devicetree/bindings/gpio/gpio.txt for further information on 49GPIO bindings. 50 51Sub-nodes: 52 53- regulators : This node defines the settings for the LDOs and BUCKs. 54 The DA9062 regulators are bound using their names listed below: 55 56 buck1 : BUCK_1 57 buck2 : BUCK_2 58 buck3 : BUCK_3 59 buck4 : BUCK_4 60 ldo1 : LDO_1 61 ldo2 : LDO_2 62 ldo3 : LDO_3 63 ldo4 : LDO_4 64 65 The DA9061 regulators are bound using their names listed below: 66 67 buck1 : BUCK_1 68 buck2 : BUCK_2 69 buck3 : BUCK_3 70 ldo1 : LDO_1 71 ldo2 : LDO_2 72 ldo3 : LDO_3 73 ldo4 : LDO_4 74 75 The component follows the standard regulator framework and the bindings 76 details of individual regulator device can be found in: 77 Documentation/devicetree/bindings/regulator/regulator.txt 78 79 regulator-initial-mode may be specified for buck regulators using mode values 80 from include/dt-bindings/regulator/dlg,da9063-regulator.h. 81 82- rtc : This node defines settings required for the Real-Time Clock associated 83 with the DA9062. There are currently no entries in this binding, however 84 compatible = "dlg,da9062-rtc" should be added if a node is created. 85 86- onkey : See ../input/da9062-onkey.txt 87 88- watchdog: See ../watchdog/da9062-watchdog.txt 89 90- thermal : See ../thermal/da9062-thermal.txt 91 92Example: 93 94 pmic0: da9062@58 { 95 compatible = "dlg,da9062"; 96 reg = <0x58>; 97 interrupt-parent = <&gpio6>; 98 interrupts = <11 IRQ_TYPE_LEVEL_LOW>; 99 interrupt-controller; 100 101 rtc { 102 compatible = "dlg,da9062-rtc"; 103 }; 104 105 regulators { 106 DA9062_BUCK1: buck1 { 107 regulator-name = "BUCK1"; 108 regulator-min-microvolt = <300000>; 109 regulator-max-microvolt = <1570000>; 110 regulator-min-microamp = <500000>; 111 regulator-max-microamp = <2000000>; 112 regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>; 113 regulator-boot-on; 114 }; 115 DA9062_LDO1: ldo1 { 116 regulator-name = "LDO_1"; 117 regulator-min-microvolt = <900000>; 118 regulator-max-microvolt = <3600000>; 119 regulator-boot-on; 120 }; 121 }; 122 }; 123
