This patch use delayed workqueue to check cable state after a certain time. If extcon-max8997 driver check cable state during booting of platform, this couldn't send the correct notification of cable state to extcon consumer. Alwasys, this driver should check cable state after the completion of platform initialization Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Myungjoo Ham <myungjoo.ham@samsung.com>

* This driver is based on max8998.h
|
|
*
|
|
* MAX8997 has PMIC, MUIC, HAPTIC, RTC, FLASH, and Fuel Gauge devices.
|
|
* Except Fuel Gauge, every device shares the same I2C bus and included in
|
|
* this mfd driver. Although the fuel gauge is included in the chip, it is
|
|
* excluded from the driver because a) it has a different I2C bus from
|
|
* others and b) it can be enabled simply by using MAX17042 driver.
