* Dialog DA9063/DA9063L 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 only)
|
|
da9063-watchdog : : Watchdog
|
|
|
|
======
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be "dlg,da9063" or "dlg,da9063l"
|
|
- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
|
|
modified to match the chip's OTP settings).
|
|
- interrupts : IRQ line information.
|
|
- interrupt-controller
|
|
|
|
Sub-nodes:
|
|
|
|
- regulators : This node defines the settings for the LDOs and BUCKs.
|
|
The DA9063(L) 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 (DA9063 only)
|
|
ldo2 : LDO_2 (DA9063 only)
|
|
ldo3 : LDO_3
|
|
ldo4 : LDO_4 (DA9063 only)
|
|
ldo5 : LDO_5 (DA9063 only)
|
|
ldo6 : LDO_6 (DA9063 only)
|
|
ldo7 : LDO_7
|
|
ldo8 : LDO_8
|
|
ldo9 : LDO_9
|
|
ldo10 : LDO_10 (DA9063 only)
|
|
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 only. The RTC is not present in DA9063L. 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 and DA9063L. 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";
|
|
};
