    arm64: dts: verdin-imx8mm: add otg2 pd to usbphy · 2fa24aa7

    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: 6a57f224 ("arm64: dts: freescale: add initial support for verdin imx8m mini")
