Subject: [PATCH 3/3] ARM: dts: imx6q-evi: Fix onboard hub reset line
Date: Thu, 11 Aug 2016 09:40:32 -0700 [thread overview]
Message-ID: <1470933632-22133-4-git-send-email-stillcompiling@gmail.com> (raw)
In-Reply-To: <1470933632-22133-1-git-send-email-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
