power: axp288_charger: Replace deprecatd API of extcon
This patch removes the deprecated notifier API of extcon framework and then use the new extcon API[2] with the unique id[1] to indicate the each external connector. Alter deprecated API as following: - extcon_register_interest() -> extcon_register_notifier() - extcon_unregister_interest() -> extcon_unregister_notifier() - extcon_get_cable_state() -> extcon_get_cable_state_() And, extcon alters the name of USB charger connector in patch[3] as following: - EXTCON_CHG_USB_SDP /* Standard Downstream Port */ - EXTCON_CHG_USB_DCP /* Dedicated Charging Port */ - EXTCON_CHG_USB_CDP /* Charging Downstream Port */ - EXTCON_CHG_USB_ACA /* Accessory Charger Adapter */ [1] Commit 2a9de9c0f08d61 - ("extcon: Use the unique id for external connector instead of string) [2] Commit 046050f6e623e4 - ("extcon: Update the prototype of extcon_register_notifier() with enum extcon [3] Commit 11eecf910bd81d - ("extcon: Modify the id and name of external connector") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-By: Sebastian Reichel <sre@kernel.org>
