So what i'll do is get the irq via platform_get_irq() and friends
and if it was a success use platform_get_resource() and friends
to get struct resource and just edit the relevant parts for the
XHCI irq resource.
Sounds OK?
something like this.
+ int ret, irq;
+ struct resource *res;
+ struct platform_device *dwc3_pdev = to_platform_device(dwc->dev);
+
+ irq = platform_get_irq_byname(dwc3_pdev, "host");
+ if (irq == -EPROBE_DEFER)
+ return irq;
+
+ if (irq <= 0) {
+ irq = platform_get_irq_byname(dwc3_pdev, "dwc_usb3");
+ if (irq == -EPROBE_DEFER)
+ return irq;
+
+ if (irq <= 0) {
+ irq = platform_get_irq(dwc3_pdev, 0);
+ if (irq <= 0) {
+ if (irq != -EPROBE_DEFER) {
+ dev_err(dwc->dev,
+ "missing host IRQ\n");
+ }
+ return irq;
+ } else {
+ res = platform_get_resource(dwc3_pdev,
+ IORESOURCE_IRQ, 0);
+ }
+ } else {
+ res = platform_get_resource_byname(dwc3_pdev,
+ IORESOURCE_IRQ,
+ "dwc_usb3");
+ }
+
+ } else {
+ res = platform_get_resource_byname(dwc3_pdev, IORESOURCE_IRQ,
+ "host");
+ }
+
+ dwc->xhci_resources[1].start = irq;
+ dwc->xhci_resources[1].end = irq;
+ dwc->xhci_resources[1].flags = res->flags;
+ dwc->xhci_resources[1].name = res->name;
