Some FTDI devices like FTX or FT232R support CBUS Bit Bang mode on CBUS
pins, allowing host to control them via simple USB control transfers.
To make use of a CBUS pin in Bit Bang mode, the pin must be configured
to I/O mode in the FTDI EEPROM. This mode perfectly coexists with regular

First of all, not receiving your mails through the mailing list. Can you

Hi Laurent,
A trivial but nice improvement.

It might be missing, but only just since the previous patch.
Perhaps this should squash into [5/8] ?

The UVC configfs implementation creates all groups as global static
variables. This prevents creation of multiple UVC function instances,
as they would all require their own configfs group instances.
Fix this by allocating all groups dynamically. To avoid duplicating code
around, extend the
The UVC format description are numbered using the descriptor's
bFormatIndex field. The index is used in UVC requests, and is thus
needed to handle requests in userspace. Make it dynamically discoverable
by exposing it in a bFormatIndex configfs attribute of the uncompressed
and mjpeg format config
Various configfs groups (represented by config_group) are wrapped in
structures that they're the only member of. This allows adding other
data fields to groups, but it unnecessarily makes the code more complex.
Remove the outer structures and use config_group directly to simplify
the code. Groups
The UVC configfs implementation is large and difficult to navigate. Add
a bit more air to the code to make it easier to read.

While checks are in place to avoid attributes and children of a format
being manipulated after the format is linked into the streaming header,
the linked flag was never actually set, invalidating the protections.

Hello,
This patch series reworks the UVC gadget function configfs implementation to
support multiple UVC functions in a single device and
The first two patches simplify the code (01/08) and improve readability
(02/08).
The series then moves to dynamically allocating all configfs groups to
Some of the .allow_link() and .drop_link() operations implementations
call config_group_find_item() and then leak the reference to the
returned item. Fix this by dropping those references where needed.
