|
|
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.
