+* Dialog DA9063 Power Management Integrated Circuit (PMIC)
+
+DA9093 consists of a large and varied group of sub-devices (I2C Only):
+
+Device Supply Names Description
+------ ------------ -----------
+da9063-regulator : : LDOs & BUCKs
+da9063-rtc : : Real-Time Clock
+da9063-watchdog : : Watchdog
+
+======
+
+Required properties:
+
+- compatible : Should be "dlg,da9063-ca", "dlg,da9063-bb" or/and
+ "dlg,da9063-ad".
+- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
+ modified to match the chip's OTP settings).
+- interrupt-parent : Specifies the reference to the interrupt controller for
+ the DA9063.
+- interrupts : IRQ line information.
+- interrupt-controller
+
+Sub-nodes:
+
+- regulators : This node defines the settings for the LDOs and BUCKs. The
+ DA9063 regulators are bound using their names listed below:
+
+ bcore1 : BUCK CORE1
+ bcore2 : BUCK CORE2
+ bpro : BUCK PRO
+ bmem : BUCK MEM
+ bio : BUCK IO
+ bperi : BUCK PERI
+ ldo1 : LDO_1
+ ldo2 : LDO_2
+ ldo3 : LDO_3
+ ldo4 : LDO_4
+ ldo5 : LDO_5
+ ldo6 : LDO_6
+ ldo7 : LDO_7
+ ldo8 : LDO_8
+ ldo9 : LDO_9
+ ldo10 : LDO_10
+ ldo11 : LDO_11
+
+ 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
+
+- rtc : This node defines settings for the Real-Time Clock associated with
+ the DA9063. There are currently no entries in this binding, however
+ compatible = "dlg,da9063-rtc" should be added if a node is created.
+
+- watchdog : This node defines settings for the Watchdog timer associated
+ with the DA9063. There are currently no entries in this binding, however
+ compatible = "dlg,da9063-watchdog" should be added if a node is created.
+
+
+Example:
+
+ pmic0: da9063@58 {
+ compatible = "dlg,da9063-ca", "dlg,da9063-bb", "dlg,da9063-ad";
+ reg = <0x58>;
+ interrupt-parent = <&gpio6>;
+ interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+
+ rtc {
+ compatible = "dlg,da9063-rtc";
+ };
+
+ wdt {
+ compatible = "dlg,da9063-watchdog";
+ };
+
+ regulators {
+ DA9063_BCORE1: bcore1 {
+ regulator-name = "BCORE1";
+ regulator-min-microvolt = <300000>;
+ regulator-max-microvolt = <1570000>;
+ regulator-min-microamp = <500000>;
+ regulator-max-microamp = <2000000>;
+ regulator-boot-on;
+ };
+ DA9063_LDO11: ldo11 {
+ regulator-name = "LDO_11";
+ regulator-min-microvolt = <900000>;
+ regulator-max-microvolt = <3600000>;
+ regulator-boot-on;
+ };
+ };
+ };
