0001 * Dialog DA9055 Power Management Integrated Circuit (PMIC)
0002
0003 DA9055 consists of a large and varied group of sub-devices (I2C Only):
0004
0005 Device Supply Names Description
0006 ------ ------------ -----------
0007 da9055-gpio : : GPIOs
0008 da9055-regulator : : Regulators
0009 da9055-onkey : : On key
0010 da9055-rtc : : RTC
0011 da9055-hwmon : : ADC
0012 da9055-watchdog : : Watchdog
0013
0014 The CODEC device in DA9055 has a separate, configurable I2C address and so
0015 is instantiated separately from the PMIC.
0016
0017 For details on accompanying CODEC I2C device, see the following:

0020 ======
0021
0022 Required properties:
0023 - compatible : Should be "dlg,da9055-pmic"
0024 - reg: Specifies the I2C slave address (defaults to 0x5a but can be modified)
0025 - interrupts: IRQ line info for da9055 chip.
0026 - interrupt-controller: da9055 has internal IRQs (has own IRQ domain).
0027 - #interrupt-cells: Should be 1, is the local IRQ number for da9055.
0028
0029 Sub-nodes:
0030 - regulators : Contain the regulator nodes. The DA9055 regulators are
0031 bound using their names as listed below:
0032
0033 buck1 : regulator BUCK1
0034 buck2 : regulator BUCK2
0035 ldo1 : regulator LDO1
0036 ldo2 : regulator LDO2
0037 ldo3 : regulator LDO3
0038 ldo4 : regulator LDO4
0039 ldo5 : regulator LDO5
0040 ldo6 : regulator LDO6
0041
0042 The bindings details of individual regulator device can be found in:

0046 Example:
0047
0048 pmic: da9055-pmic@5a {
0049 compatible = "dlg,da9055-pmic";
0050 reg = <0x5a>;
0051 interrupt-parent = <&intc>;
0052 interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
0053 interrupt-controller;
0054 #interrupt-cells = <1>;
0055
0056 regulators {
0057 buck1: BUCK1 {
0058 regulator-min-microvolt = <725000>;
0059 regulator-max-microvolt = <2075000>;
0060 };
0061 buck2: BUCK2 {
0062 regulator-min-microvolt = <925000>;
0063 regulator-max-microvolt = <2500000>;
0064 };
0065 ldo1: LDO1 {
0066 regulator-min-microvolt = <900000>;
0067 regulator-max-microvolt = <3300000>;
0068 };
0069 };
0070 };
