* 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"; |
|
}; |
|
|
|
onkey { |
|
compatible = "dlg,da9063-onkey"; |
|
dlg,disable-key-power; |
