From 0c64a21e6f1567aa49dbcc96a7beefeb20cf5bce Mon Sep 17 00:00:00 2001 From: Philippe Schenker Date: Thu, 11 Aug 2022 16:07:38 +0200 Subject: [PATCH] arm64: dts: verdin-imx8mm: add otg2 pd to usbphy [ Upstream commit 2fa24aa721ebb3a83dd2093814ba9a5dcdaa3183 ] The Verdin iMX8M Mini System on Module does not have USB-ID signal connected on Verdin USB_2 (usbotg2). On Verdin Development board this is no problem, as we have connected a USB-Hub that is always connected. However, if Verdin USB_2 is desired to be used as a single USB-Host port the chipidea driver does not detect if a USB device is plugged into this port, due to runtime pm shutting down the PHY. Add the power-domain &pgc_otg2 to &usbphynop2 in order to detect plugging events and enumerate the usb device.
