Subject: [edk2-platforms][PATCH 1/1] Platform/RaspberryPi: Fix dwc2 reset on raspberry pi boards
Date: Thu, 11 Mar 2021 13:40:11 +0100 [thread overview]
Message-ID: <7669a539-91a0-7b48-a6b7-897dbfeda3ae@measite.de> (raw)
DwHcReset expects attributes as the second argument. A reset is
performed if the passed attribute is valid. However 0 is not a valid
attribute and will thus never cause a controller reset.
Passing EFI_USB_HC_RESET_HOST_CONTROLLER will reset the dwc2 controller
as expected.
This enables the USB 2.0 port of the raspberry compute module 4.
