From 1468a1cc72afa210c35a4d0ed533de29110de648 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Mon, 29 Jun 2020 10:12:59 +0800 Subject: usb: ci_udc: Add function to remove usb device When unregister gadget driver in ci_udc, the usb device is not removed or stop. This causes next "usb start" fails to work. Add a new interface "usb_remove_ehci_gadget" in usb-uclass to remove the usb device for DM driver. Using "usb_lowlevel_stop" for non-DM driver.
