2019-02-01usb: ether: call _usb_eth_halt() if initialization failsJean-Jacques Hiblot
If the host does not respond in time, the initialization fails. However the usb ether driver will still be registered. This will make usb_gadget_probe_driver() fail the next time the initialization is attempted because it cannot find an available UDC. Fixing this by calling _usb_eth_halt() when the init fails.

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.

When the device is in peripheral mode there is no struct usb_bus_priv allocated pointer, as the uclass driver ("usb_dev_generic") doesn't call per_device_auto_alloc_size.

2018-12-14usb: composite: Fix max packet size for USB3.0Siva Durga Prasad Paladugu
For USB3.0, the max packetsize for GET_DESCRIPTOR should be sent as exponent value for 2. This means for 512, max packet size should be filled with 9(2^9=512). Also, fill the USB version field with 3.0 if speed is negotiated to Superspeed. This fixes the issue of DFU gadget download failure with superspeed. Without this patch, the max packet size is overflowed to zero as the bMaxPacketsize is of u8 and hence host is not able to detect this device.

2018-12-14usb: musb-new: Add support for DM_USBJean-Jacques Hiblot
Enable DM for USB peripheral in the musb-new driver. Also make sure that the driver can be used in the SPL. This implies that: * the driver must work with and without the OF_CONTROL option. That in turn, implies that the platform data can be passed in a struct ti_musb_platdata or be read from the dtb * usb.o is linked in the SPL if host support is enabled Another change is that the driver does not fail to bind (and stop the boot process) if one of the child driver does not bind. Reporting the error is enough. This kind of error would appear if the port is configured in the DTS but the driver is not activated in the config.

When CONFIG_SPL_DM_USB was added, it was added defaulted on without protection to ensure it didn't get set for non-DM SPL builds. This leads to unexpected and confusing failures when building a DM based U-Boot but with a non-DM SPL, as the defconfig is unlikely to have CONFIG_SPL_DM_USB actively disabled.
