Currently it is possible to build in some subset of usb functions
*OR* some gadget module. This is limited only by Kconfig not
any functionality.
This patch removes this limitation. With this patch it is possible
to set up all build combinations:
1) Multiple gadgets build in
2) Part of functions build in, part of functions as a modules
3) Some gadgets build in and some part of functions build in/modules
etc.
As this patch makes Kconfig quite complicated let me clarify how it works:
USB_F_<func name> - used in makefile for compilation
USB_CONFIGFS_F_<func name> - Chosen by user in function menu
USB_G_<gadget name>_REQ_F_<func name> - set up by gadget to mark
that this particular gadget requires this func to work
USB_F_<func name>_SELECTOR - helper config which is used to determine
if function should be build in or compiled as a module
The rules are quite simple:
1) If any of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, then USB_F_<func name> is set to y and function is build in
2) If none of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, but any of them equals m then USB_F_<func name> is set to m and function
is compiled as a module

- A Linux "Gadget Driver" talks to the USB Peripheral Controller
- driver through the abstract "gadget" API. Some other operating
- systems call these "client" drivers, of which "class drivers"
- are a subset (implementing a USB device class specification).
- A gadget driver implements one or more USB functions using
- the peripheral hardware.
-
- Gadget drivers are hardware-neutral, or "platform independent",
- except that they sometimes must understand quirks or limitations
- of the particular controllers they work with. For example, when
- a controller doesn't support alternate configurations or provide
- enough of the right types of endpoints, the gadget driver might
- not be able work with that controller, or might need to implement
- a less common variant of a device class protocol.
-
-# this first set of drivers all depend on bulk-capable hardware.

- A Linux USB "gadget" can be set up through configfs.
- If this is the case, the USB functions (which from the host's
- perspective are seen as interfaces) and configurations are
- specified simply by creating appropriate directories in configfs.
- Associating functions with configurations is done by creating
- appropriate symbolic links.
