Hans de Goede fcdd8aaa48 dm: usb: Fix finding of first upstream usb-2 hub in the ehci dm code ... The ehci driver model code for finding the first upstream usb-2 hub before this commit has a number of issues: 1) "if (!ttdev->speed != USB_SPEED_HIGH)" does not work because the '!' takes presedence over the '!=' this should simply be "if (ttdev->speed == USB_SPEED_HIGH)" 2) It makes ttdev point to the first upstream usb-2 hub, but ttdev should point to the last usb-1 device before the first usb-2 hub (when going upstream from the device), as ttdev is used to find the port of the first usb-2 hub to which the the last usb-1 device is connected. 3) parent_devnum however should be set to the devnum of the first usb-2 hub, so we need to keep pointers around to both usb_device structs. To complicate things further during enumeration usb_device.dev will point to the parent udevice, where as during normal use it will point to the actual udevice, we must handle both cases correctly. This commit fixes all this making usb-1 devices attached to usb-2 hubs, including usb-1 devices attached to usb-1 hubs attached to usb-2 hubs, work.
