USB3.0 host xHCI驱动

xHCI驱动在usb/host中，主要初始化xHCI。xHCI作为usb host部分的驱动。

1. xhci driver与device的匹配

usb/host/xhci-plat.c：

static struct platform_driver usb_xhci_driver = {
    .probe  = xhci_plat_probe,
    .remove = xhci_plat_remove,
    .shutdown = usb_hcd_platform_shutdown,
    .driver = {
        .name = "xhci-hcd",
        .pm = &xhci_plat_pm_ops,
        .of_match_table = of_match_ptr(usb_xhci_of_match),
        .acpi_match_table = ACPI_PTR(usb_xhci_acpi_match),
    },
};
MODULE_ALIAS("platform:xhci-hcd");
 
 
static int __init xhci_plat_init(void)
{
    xhci_init_driver(&xhci_plat_hc_driver, &xhci_plat_overrides);
    return platform_driver_register(&usb_xhci_driver);
}
module_init(xhci_plat_init);

从usb_xhci_driver可以看出有两种匹配方式去执行xhci_plat_probe：

1.1 driver.name

platform_driver.driver.name
