2019-03-16usb: udc-uclass: Fixed problem when no alias is defined in DTJean-Jacques Hiblot
commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports" changed the way the udevice if found. It uses the alias to find a udevice for a given USB port number. In the commit log it was stated that if no alias is provided, the bind order will be used instead. However it doesn't work. Fixing this by adding a call to uclass_get_device() if uclass_get_device_by_seq() fails. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com> Tested-by: Vignesh R <vigneshr@ti.com>
2019-01-10dm: usb: gadget: Fix boot breakage on sunxi platformsJean-Jacques Hiblot
Fixes commit 013116243950 ("dm: usb: create a new UCLASS ID for USB gadget devices") The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared even for platforms that do not enable DM_USB_GADGET. Otherwise the driver for their usb peripheral controller fails to bind.

2019-01-10dm: usb: udc: Use SEQ_ALIAS to index the USB gadget portsJean-Jacques Hiblot
dfu, fastbot and other usb gadget commands take the USB port index as a parameter. Currently this index is assigned in the order of the driver bindings. Changing this behavior using the SEQ_ALIAS feature. This option assign to the device a SEQ number based on its alias (if it exists) To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing naming convention: use "usb" for the name of the gadget UCLASS_DRIVER (same as for the UCLASS_USB). If no alias is provided, then the index falls back to the order in which the bindings took place.

2018-12-07dm: usb: create a new UCLASS ID for USB gadget devicesJean-Jacques Hiblot
UCLASS_USB_DEV_GENERIC was meant for USB devices connected to host controllers, not gadget devices. Adding a new UCLASS for gadget devices alone. Also move the generic DM code for USB gadgets in a separate file for clarity. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
