Subject: [PATCH 8/8] ARM: dts: imx6q-evi: Fix onboard hub reset line
Date: Tue, 3 Jan 2017 14:33:31 +0800 [thread overview]
Message-ID: <1483425211-14473-9-git-send-email-peter.chen@nxp.com> (raw)
In-Reply-To: <1483425211-14473-1-git-send-email-peter.chen@nxp.com>
From: Joshua Clayton <stillcompiling@gmail.com>
Previously the onboard hub was made to work by treating its
reset gpio as a regulator enable.
Get rid of that kludge now that pwseq has added reset gpio support
Move pin muxing the hub reset pin into the usbh1 group
