Hi,
This series adds a number of smaller improvements to the USB Type-C
Connector class code, including new helpers for cables, new
definitions for the latest standard versions, support for the Enter
Mode VDO, etc.
The series also includes patches that are meant to (partially) prepare
the subsystem for USB4 support, and for Thundebolt3 alternate mode.
Especially the new Enter_Mode Message that USB4 requires is considered
with the definitions for the "USB mode" (which can be usb2, usb3 or
usb4), which is one of the fields in that message. Later we will need
to allow the user to control the USB mode, but I'm not including the
patches that add the attributes for that in this series. I'll send
them separately as RFC following this series.
thanks,
Heikki Krogerus (15):
