Cool, nxp is also using dwc3 :-) C'mon Rajesh, send us a glue layer :) > diff --git a/drivers/usb/dwc3/host.c b/drivers/usb/dwc3/host.c > index c679f63..4d5b783 100644 > --- a/drivers/usb/dwc3/host.c > +++ b/drivers/usb/dwc3/host.c > @@ -17,6 +17,7 @@ > > #include <linux/platform_device.h> > #include <linux/usb/xhci_pdriver.h> > +#include <linux/of_device.h> > > #include "core.h" > > @@ -32,6 +33,9 @@ int dwc3_host_init(struct dwc3 *dwc) > return -ENOMEM; > } > > + if (IS_ENABLED(CONFIG_OF) && dwc->dev->of_node) > + of_dma_configure(&xhci->dev, dwc->dev->of_node); okay, so we have a long discussion about this going on. You can catch up with it starting here: http://marc.info/?i=1461612094-30939-1-git-send-email-grygorii.stras...@ti.com At least for now, this patch will be applied. We need to have a better solution for this, one that helps not only DT platforms. -- balbi
