Subject: [PATCH v10 8/8] ARM: dts: imx6q-evi: Fix onboard hub reset line
Date: Mon, 14 Nov 2016 09:35:59 +0800	[thread overview]
Message-ID: <1479087359-7547-9-git-send-email-peter.chen@nxp.com> (raw)
In-Reply-To: <1479087359-7547-1-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
