From 2333d2a72ba1332b0e81f76f1a9a516b863374d6 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Tue, 5 Apr 2022 12:35:09 -0700 Subject: [PATCH] ARM: dts: imx8mm-venice-gw{71xx,72xx,73xx}: fix OTG controller OC mode commit 4c79865f3e8a2db93ec1e844509edfebe5a6ae56 upstream. The GW71xx, GW72xx and GW73xx boards have USB1 routed to a USB OTG connectors and USB2 routed to a USB hub. The OTG connector has a over-currently protection with an active-low pin and the USB1 to HUB connection has no over-current protection (as the HUB itself implements this for its downstream ports). Add proper dt nodes to specify the over-current pin polarity for USB1 and disable over-current protection for USB2.
