I tested this patch on Porter, but interrupt of "usb-otg" didn't happened
even if I connected/disconnected a usb convert cable (usb micro-ab to A).
Remarks: I confirmed that the usb convert cable worked correctly on other board.
Do I need other settings for this?
- kernel : renesas.git / renesas-devel-20160127-v4.5-rc1 tag + this patch
- config : shmobile_defconfig + EXTCON + MAX3355 + and more
- board : Porter (Y-RCAR-M2-PORTER-A)
- log :
