This patch has a conflict. You have to always implement patch on extcon branch
including latest patch. You need to resend v2 patch based on extcon-next branch.

'extcon-twl.txt' is renamed as 'extcon-palmas.txt' on following patch:
http://git.kernel.org/cgit/linux/kernel/git/chanwoo/extcon.git/commit/?h=extcon-next&id=80d644b297dc26c5126858555044edef76f4ffe8

And, 'vbus-supply' phandle was removed on following patch:
http://git.kernel.org/cgit/linux/kernel/git/chanwoo/extcon.git/commit/?h=extcon-next&id=26ece4f0b7d2264282d9077d1843ff1e98189b6c

Thanks,
Chanwoo Choi
