linux-toradex.git/drivers/extcon, branch v4.4-rc6 Linux kernel for Apalis and Colibri modules extcon: Modify the id and name of external connector 2015-10-15T23:30:09+00:00 Chanwoo Choi cw00.choi@samsung.com 2015-10-03T05:15:13+00:00 11eecf910bd81d36425020743b2df73651c5b466 This patch modifies the id and name of external connector with the additional prefix to clarify both attribute and meaning of external connector as following: - EXTCON_CHG_* mean the charger connector. - EXTCON_JACK_* mean the jack connector. - EXTCON_DISP_* mean the display port connector.
