From 71cbe0d681d4288d090a404273ce6b0c1c14b617 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 14 Jun 2015 17:40:37 +0200 Subject: [PATCH] sunxi: musb: Add id pin support When in host mode check if there is a host cable inserted into the otg port by checking the id pin. If there is no host cable return an error to make usb_lowlevel_init() exit early, rather then waiting for 1 second for a device which will never show up.
