Subject: [PATCH] usb: dwc3: Softdep for GBit Ethernet on Odroid XU4
Date: Thu, 21 Mar 2019 21:23:03 +0100	[thread overview]
Message-ID: <20190321202303.GA1399@vis> (raw)

[-- Attachment #1: Type: text/plain, Size: 1246 bytes --]

This adds a soft dependency to the dwc3 module to load it after
xhci-plat as proposed in:

https://marc.info/?l=linux-usb&m=155230272022603&w=2

Old behaviour:

$ lsusb -t
/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M
   |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=r8152, 480M

New behaviour:

$ lsusb -t
/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M
   |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=r8152, 5000M

Tested on Debian unstable using Linux 4.19.29.

Note, this needs a hard reset when coming from an unpatched kernel.
