[U-Boot] [PATCH 1/3] usb: gadget: ether: Perform board initialization from ethernet gadget driver

[Kishon Vijay Abraham I]

Ethernet gadget driver can be used both by both SPL and u-boot. Since
usb_eth_init() is the entry point for ethernet gadget driver, perform
board initialization there. Also perform the cleanup in usb_eth_halt.

[U-Boot] [PATCH 2/3] usb: host: xhci-omap: invoke board_usb_cleanup in xhci_hcd_stop

[Kishon Vijay Abraham I]

xhci omap driver has board_usb_init in xhci_hcd_init but doesn't have
the corresponding cleanup function in xhci_hcd_stop.

Fix it here by invoking board_usb_cleanup() in xhci_hcd_stop().

[U-Boot] [PATCH 3/3] usb: gadget: ether: populate _reset_ callback

[Kishon Vijay Abraham I]

populate _reset_ callback to the USB ethernet gadget since UDC core
expects every gadget driver to have the reset callback. This shouldn't
be needed once the ethernet gadget driver is adapted to use the
composite driver.

I'm not sure about this one, Lukasz, can you please comment ?
