Subject: [PATCH v2] arm64: dts: verdin-imx8mm: add otg2 pd to usbphy
Date: Thu, 11 Aug 2022 16:07:38 +0200	[thread overview]
Message-ID: <20220811140738.96348-1-dev@pschenker.ch> (raw)

From: Philippe Schenker <philippe.schenker@toradex.com>

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.

Fixes: 6a57f224f734 ("arm64: dts: freescale: add initial support for verdin imx8m mini")
Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>

Changes in v2:
- Changed word VBUS to USB-ID, as from mailinglist discussions I
  obviously mixed that up before.
