* 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-onkey : : On Key da9063-rtc : : Real-Time Clock da9063-watchdog : : Watchdog ====== Required properties: - compatible : Should be "dlg,da9063" - 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. - onkey : This node defines the OnKey settings for controlling the key functionality of the device. The node should contain the compatible property with the value "dlg,da9063-onkey". Optional onkey properties: - dlg,disable-key-power : Disable power-down using a long key-press. If this entry exists the OnKey driver will remove support for the KEY_POWER key press. If this entry does not exist then by default the key-press triggered power down is enabled and the OnKey will support both KEY_POWER and KEY_SLEEP. - 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" reg = <0x58>; interrupt-parent = <&gpio6>; interrupts = <11 IRQ_TYPE_LEVEL_LOW>; interrupt-controller; rtc { compatible = "dlg,da9063-rtc"; }; wdt { compatible = "dlg,da9063-watchdog"; }; onkey { compatible = "dlg,da9063-onkey"; dlg,disable-key-power; }; 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; }; }; };
