Subject: ARM: dts: imx7d-smegw01: Fix USB host over-current polarity
From: Fabio Estevam <festevam@xxxxxxx>
commit 1febf88ef907b142fdde34f7c64ed3535d9339e4 upstream.
Currently, when resetting the USB modem via AT commands, the modem is
no longer re-connected.
This problem is caused by the incorrect description of the USB_OTG2_OC
pad. It should have pull-up enabled, hysteresis enabled and the
property 'over-current-active-low' should be passed.
With this change, the USB modem can be successfully re-connected
after a reset.
