Subject: [PATCH v4 1/6] usb: musb: core: Handle Babble condition only in HOST mode
Date: Mon, 19 May 2014 19:09:31 +0530 [thread overview]
Message-ID: <1400506776-2816-2-git-send-email-george.cherian@ti.com> (raw)
In-Reply-To: <1400506776-2816-1-git-send-email-george.cherian@ti.com>
BABBLE and RESET share the same interrupt. The interrupt
is considered to be RESET if MUSB is in peripheral mode and
as a BABBLE if MUSB is in HOST mode.
Handle babble condition iff MUSB is in HOST mode.
