There are currently no entries in this binding, however 74 compatible = "dlg,da9062-rtc" should be added if a node is created. 75 76- onkey : See ../input/da9062-onkey.txt 77 78- watchdog: See ../watchdog/da9062-watchdog.txt 79 80- thermal : See ../thermal/da9062-thermal.txt 81 82Example: 83 84 pmic0: da9062@58 { 85 compatible = "dlg,da9062"; 86 reg = <0x58>; 87 interrupt-parent = <&gpio6>; 88 interrupts = <11 IRQ_TYPE_LEVEL_LOW>; 89 interrupt-controller; 90 91 rtc { 92 compatible = "dlg,da9062-rtc"; 93 }; 94 95 regulators { 96 DA9062_BUCK1: buck1 { 97 regulator-name = "BUCK1"; 98 regulator-min-microvolt = <300000>; 99 regulator-max-microvolt = <1570000>; 100 regulator-min-microamp = <500000>; 101 regulator-max-microamp = <2000000>; 102 regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>; 103 regulator-boot-on; 104 }; 105 DA9062_LDO1: ldo1 { 106 regulator-name = "LDO_1"; 107 regulator-min-microvolt = <900000>; 108 regulator-max-microvolt = <3600000>; 109 regulator-boot-on; 110 }; 111 }; 112 }; 113 114
