Subject: [PATCH v2 2/3] doc: usb: ci-hdrc-usb2: add property over-current-active-high
Date: Wed, 20 Jul 2016 16:02:41 +0800 [thread overview]
Message-ID: <1469001762-15015-2-git-send-email-jun.li@nxp.com> (raw)
In-Reply-To: <1469001762-15015-1-git-send-email-jun.li-3arQi8VN3Tc@public.gmane.org>
Adding over-current-active-high to indicate the over current flag
is high active as typically we use active low for over current
polarity.
