EXTCON FOR GPIO-STATES
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
- compatible : Should be "extcon-gpio-states";
|
||
|
|
|
||
|
|
Optional Properties:
|
||
|
|
- extcon-gpio,name: Name of extcon device.
|
||
|
|
- gpios: List of teh gpios.
|
||
|
|
- extcon-gpio,irq-flags: IRQ flags for GPIO.
|
||
|
|
- extcon-gpio,debounce: Debounce time in ms.
|
||
|
|
- extcon-gpio,wait-for-gpio-scan: Wait timeout for scanning all gpio states
|
||
|
|
after chnage found in gpio and debounce timeof gpio is completed.
|
||
|
|
- extcon-gpio,out-cable-names: Output cable names.
|
||
|
|
- extcon-gpio,cable-states: GPIO states and ther corresponding output cable
|
||
|
|
state. This is array of the data for table as
|
||
|
|
gpio-state <-> output cable-state
|
||
|
|
- cable-connected-on-boot: Cable connected on boot. It should be cable index
|
||
|
|
in the output cable names. The number start from 0. Absence of this
|
||
|
|
property will be assume as there is no cable connected. This property
|
||
|
|
will be valid if there is no gpios provided for cable states.
|
||
|
|
- wakeup-source: Boolean, device can wake-up the system.
|
||
|
|
|
||
|
|
This driver also supports the extcon interface for different cable without
|
||
|
|
gpios. On this case, if property cable-connected-on-boot provided then
|
||
|
|
it will be consider this as the default cable otherwise it will assume
|
||
|
|
that there is no cable connected. Later on, through extcon sysfs, the
|
||
|
|
state can be chnaged.
