External connector devices that decides connection information based on ADC values may use adc-jack device driver. The user simply needs to provide a table of adc range and connection states. Then, extcon framework will automatically notify others. Changes in V1: added Lars-Peter Clausen suggested changes: Using macros to get rid of boiler plate code such as devm_kzalloc and module_platform_driver.Other changes suggested are related to coding guidelines. Changes in V2: Removed some unnecessary checks and changed the way we are un-regitering extcon and freeing the irq while removing. Changes in V3: Renamed the files to comply with extcon naming. Changes in V4: Added the cancel_work_sync during removing of driver. Changes in V5: Added the dependency of IIO in Kconfig. Changes in V6: Some nitpicks related to naming.

Say Y here to enable external connector class (extcon) support.
|
|
This allows monitoring external connectors by userspace
|
|
via sysfs and uevent and supports external connectors with
|
|
multiple states; i.e., an extcon that may have multiple
|
|
cables attached. For example, an external connector of a device
|
|
may be used to connect an HDMI cable and a AC adaptor, and to
|
|
host USB ports. Many of 30-pin connectors including PDMI are
|
|
also good examples.
