0029 Required properties:
0030
0031 - compatible : Should be
0032 "dlg,da9062" for DA9062
0033 "dlg,da9061" for DA9061
0034 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
0035 modified to match the chip's OTP settings).
0036 - interrupts : IRQ line information.
0037 - interrupt-controller
0038
0039 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
0040 further information on IRQ bindings.
0041
0042 Optional properties:
0043
0044 - gpio-controller : Marks the device as a gpio controller.
0045 - #gpio-cells : Should be two. The first cell is the pin number and the
0046 second cell is used to specify the gpio polarity.
0047
0048 See Documentation/devicetree/bindings/gpio/gpio.txt for further information on
0049 GPIO bindings.
0050
0051 Sub-nodes:
0052
0053 - regulators : This node defines the settings for the LDOs and BUCKs.
0054 The DA9062 regulators are bound using their names listed below:
0055
0056 buck1 : BUCK_1
0057 buck2 : BUCK_2
0058 buck3 : BUCK_3
0059 buck4 : BUCK_4
0060 ldo1 : LDO_1
0061 ldo2 : LDO_2
0062 ldo3 : LDO_3
0063 ldo4 : LDO_4
0064
0065 The DA9061 regulators are bound using their names listed below:
0066
0067 buck1 : BUCK_1
0068 buck2 : BUCK_2
0069 buck3 : BUCK_3
0070 ldo1 : LDO_1
0071 ldo2 : LDO_2
0072 ldo3 : LDO_3
0073 ldo4 : LDO_4
0074
0075 The component follows the standard regulator framework and the bindings
0076 details of individual regulator device can be found in:
0077 Documentation/devicetree/bindings/regulator/regulator.txt
0078
0079 regulator-initial-mode may be specified for buck regulators using mode values
0080 from include/dt-bindings/regulator/dlg,da9063-regulator.h.
0081
0082 - rtc : This node defines settings required for the Real-Time Clock associated
0083 with the DA9062. There are currently no entries in this binding, however
0084 compatible = "dlg,da9062-rtc" should be added if a node is created.
0085
0086 - onkey : See ../input/da9062-onkey.txt
0087
0088 - watchdog: See ../watchdog/da9062-watchdog.txt
0089
0090 - thermal : See ../thermal/da9062-thermal.txt
0091
