Optional properties: - gpio-controller : Marks the device as a gpio controller. - #gpio-cells : Should be two. The first cell is the pin number and the second cell is used to specify the gpio polarity. See Documentation/devicetree/bindings/gpio/gpio.txt for further information on GPIO bindings. - interrupts : IRQ line information. - interrupt-controller See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for further information on IRQ bindings. Sub-nodes: - regulators : This node defines the settings for the LDOs and BUCKs. The DA9062 regulators are bound using their names listed below: buck1 : BUCK_1 buck2 : BUCK_2 buck3 : BUCK_3 buck4 : BUCK_4 ldo1 : LDO_1 ldo2 : LDO_2 ldo3 : LDO_3 ldo4 : LDO_4 The DA9061 regulators are bound using their names listed below: buck1 : BUCK_1 buck2 : BUCK_2 buck3 : BUCK_3 ldo1 : LDO_1 ldo2 : LDO_2 ldo3 : LDO_3 ldo4 : LDO_4 The component follows the standard regulator framework and the bindings details of individual regulator device can be found in: Documentation/devicetree/bindings/regulator/regulator.txt regulator-initial-mode may be specified for buck regulators using mode values from include/dt-bindings/regulator/dlg,da9063-regulator.h. - rtc : This node defines settings required for the Real-Time Clock associated with the DA9062. There are currently no entries in this binding, however compatible = "dlg,da9062-rtc" should be added if a node is created. - onkey : See ../input/da9062-onkey.txt - watchdog: See ../watchdog/da9062-wdt.txt - thermal : See ../thermal/da9062-thermal.txt Example: pmic0: da9062@58 { compatible = "dlg,da9062"; reg = <0x58>; interrupt-parent = <&gpio6>; interrupts = <11 IRQ_TYPE_LEVEL_LOW>; interrupt-controller; rtc { compatible = "dlg,da9062-rtc"; }; regulators { DA9062_BUCK1: buck1 { regulator-name = "BUCK1"; regulator-min-microvolt = <300000>; regulator-max-microvolt = <1570000>; regulator-min-microamp = <500000>; regulator-max-microamp = <2000000>; regulator-initial-mode = <DA9063_BUCK_MODE_SYNC>; regulator-boot-on; }; DA9062_LDO1: ldo1 { regulator-name = "LDO_1"; regulator-min-microvolt = <900000>; regulator-max-microvolt = <3600000>; regulator-boot-on; }; }; }; |
