| |
| Required properties: |
| |
| - compatible : Should be |
| "dlg,da9062" for DA9062 |
| "dlg,da9061" for DA9061 |
| - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be |
| modified to match the chip's OTP settings). |
| |
| 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; |
| }; |
| }; |
| }; |
