Subject: [PATCH 2/4] doc: dt-binding: ci-hdrc-usb2: add i.mx specific binding "need-three-clocks"
Date: Wed, 16 Sep 2015 09:49:41 +0800 [thread overview]
Message-ID: <1442368183-8103-2-git-send-email-peter.chen@freescale.com> (raw)
In-Reply-To: <1442368183-8103-1-git-send-email-peter.chen-KZfg59tc24xl57MIdRCFDg@public.gmane.org>
Some SoCs needs three clock to let controller work, but others only
need one, add one property to differentiate this.
