Subject: [PATCH 7/9] ARM: dts: imx6q-evi: Fix onboard hub reset line
|
|
|
|
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
|
