There is something strange with dwc3_meson_g12a_usb2_init.
enum phy_mode mode is added here but it's not used inside this function
I also think that we should not pass enum phy_mode to
dwc3_meson_g12a_usb_otg_apply_mode
I'm aware that the original function used enum phy_mode inside but
this doesn't seem right:
we're not configuring a PHY there
instead we're setting up the OTG switch so I think we should use enum
usb_role instead
[...]
not part of this patch but should be:
there's a still a direct call to dwc3_meson_g12a_usb_init() in
dwc3_meson_g12a_resume()
I think that needs to be changed to priv->drvdata->usb_init(priv); as well
