Hi Felipe & Alan,
To continue with topic discussed at
http://www.spinics.net/lists/linux-usb/msg105279.html,
I implement the gadget bus to bind udc to gadget driver follow
most ideas from your two.
While the idea is interesting I think some aspects of the implementation
must be thought over.
Hi Andrzej, thanks for running tests and giving comments.

I intended to run more gadget (including gadgetfs) when I make v2 patch.
Please note that gadgetfs is something totally different than configfs.
Gadgetfs is a tool to build gadget's functionality entirely in userspace,
that is to handle setup requests and so on, all in userspace.
Configfs is used to compose gadgets at runtime, as opposed to the traditional
(legacy) way of composing the gadgets which is to define configurations and
select functions to be provided by writing code of a module. For example,
in g_ether there are two configurations and 4 functions: ECM, ECM subset,
EEM and RNDIS. Configuration @ index 2 contains RNDIS and configuration
@ index 1 contains one of the others. This is all hardcoded in ether.c.
With configfs you create gadgets of available _kernel_ components at runtime.
