Subject: [PATCH v4 00/11] Add XU support to UVC Gadget
Date: Thu, 2 Feb 2023 13:54:57 +0000 [thread overview]
Message-ID: <20230202135508.447109-1-dan.scally@ideasonboard.com> (raw)
Hello all
This series adds support for the definition of extension units in configfs for
the UVC Gadget. The XUs are modelled as config_items within a new "extensions"
group under control, which seemed like an appropriate place to put them.
To allow the XU's to be inserted in the function graph, the bSourceID attribute
for the default output terminal is made writeable - users will need to configure
it with the bUnitID of the XU that they want to use as the OT's source. This does
mean that the XUs can _only_ be placed immediately preceding the OT, but I think
that that's fine for now.
The XUs configured through this series have been tested via uvc-gadget, uvcvideo
and uvcdynctrl.
This version is almost identical to v3 but rebased onto usb-testing, with minor
changes to 6/11 and 7/11.
v2 of the series here: https://lore.kernel.org/linux-usb/0ae65812-c937-d071-455b-7c1d6418b080@ideasonboard.com/
Thanks
Dan
