Subject: [PATCH v3 05/11] usb: hcd.h: Add OTG to HCD interface
Date: Wed, 8 Jul 2015 13:19:31 +0300 [thread overview]
Message-ID: <1436350777-28056-6-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1436350777-28056-1-git-send-email-rogerq@ti.com>
The OTG core will use struct otg_hcd_ops to
add/remove the HCD controller.
The main purpose of this interface is to avoid directly
calling usb_add/remove_hcd() from the OTG core as they
wouldn't be defined in the built-in symbol table if
CONFIG_USB is m.
