-Subject: [PATCH] usb: dwc2: Avoid suspending if we're in gadget mode (#1825)
-
-I've found when booting HiKey with the usb gadget cable attached
-if I then try to connect via adb, I get an infinite spew of:
-
-dwc2 f72c0000.usb: dwc2_hsotg_ep_sethalt(ep ffffffc0790ecb18 ep1out, 0)
-dwc2 f72c0000.usb: dwc2_hsotg_ep_sethalt(ep ffffffc0790eca18 ep1in, 0)
-
-It seems that the usb autosuspend is suspending the bus shortly
-after bootup when the gadget cable is attached. So when adbd
-then tries to use the device, it doesn't work and it then tries
-to restart it over and over via the ep_sethalt calls (via
-FUNCTIONFS_CLEAR_HALT ioctl).
-
-Chen Yu suggested this patch to avoid suspending if we're
-in device mode, and it avoids the problem.
