usb: gadget: Gadget directory cleanup - group legacy gadgets
The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the legacy gadgets (i.e. those not using configfs) into a separate directory. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

Gadget Zero is a two-configuration device. It either sinks and
|
|
||||||
sources bulk data; or it loops back a configurable number of
|
|
||||||
transfers. It also implements control requests, for "chapter 9"
|
|
||||||
conformance. The driver needs only two bulk-capable endpoints, so
|
|
||||||
it can work on top of most device-side usb controllers. It's
|
|
||||||
useful for testing, and is also a working example showing how
|
|
||||||
USB "gadget drivers" can be written.
|
|
||||||
|
|
||||||
Make this be the first driver you try using on top of any new
|
|
||||||
USB peripheral controller driver. Then you can use host-side
|
|
||||||
test software, like the "usbtest" driver, to put your hardware
|
|
||||||
and its driver through a basic set of functional tests.
|
|
||||||
|
|
||||||
Gadget Zero also works with the host-side "usb-skeleton" driver,
|
|
||||||
and with many kinds of host-side test software. You may need
|
|
||||||
to tweak product and vendor IDs before host software knows about
|
|
||||||
this device, and arrange to select an appropriate configuration.
|

||||||

This driver implements Ethernet style communication, in one of
|
|
||||||
several ways:
|
|
||||||
|
|
||||||
- The "Communication Device Class" (CDC) Ethernet Control Model.
|
|
||||||
That protocol is often avoided with pure Ethernet adapters, in
|
|
||||||
favor of simpler vendor-specific hardware, but is widely
|
|
||||||
supported by firmware for smart network devices.
|
|
||||||
|
|
||||||
- On hardware can't implement that protocol, a simple CDC subset
|
|
||||||
is used, placing fewer demands on USB.
|
|
||||||
|
|
||||||
- CDC Ethernet Emulation Model (EEM) is a newer standard that has
|
|
||||||
a simpler interface that can be used by more USB hardware.
|
|
||||||
|
|
||||||
RNDIS support is an additional option, more demanding than than
|
|
||||||
subset.
|
|
||||||
|
|
||||||
Within the USB device, this gadget driver exposes a network device
|
|
||||||
"usbX", where X depends on what other networking devices you have.
|
|
||||||
Treat it like a two-node Ethernet link: host, and gadget.
|
|
||||||
|
|
||||||
The Linux-USB host-side "usbnet" driver interoperates with this
|
|
||||||
driver, so that deep I/O queues can be supported. On 2.4 kernels,
|
|
||||||
use "CDCEther" instead, if you're using the CDC option. That CDC
|
|
||||||
mode should also interoperate with standard CDC Ethernet class
|
|
||||||
drivers on other host operating systems.

CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM

and therefore can be supported by more hardware. Technically ECM and

EEM are designed for different applications. The ECM model extends

the network interface to the target (e.g. a USB cable modem), and the
|
|
||||||
EEM model is for mobile devices to communicate with hosts using

ethernet over USB. For Linux gadgets, however, the interface with

the host is the same (a usbX device), so the differences are minimal.

Gadget Zero is a two-configuration device. It either sinks and
|
||||||
|
sources bulk data; or it loops back a configurable number of
|
||||||
|
transfers. It also implements control requests, for "chapter 9"
|
||||||
|
conformance. The driver needs only two bulk-capable endpoints, so
|
||||||
|
it can work on top of most device-side usb controllers. It's
|
||||||
|
useful for testing, and is also a working example showing how
|
||||||
|
USB "gadget drivers" can be written.
|
||||||

Make this be the first driver you try using on top of any new
|

|
USB peripheral controller driver. Then you can use host-side

test software, like the "usbtest" driver, to put your hardware
|

|
and its driver through a basic set of functional tests.
|
||||||

Gadget Zero also works with the host-side "usb-skeleton" driver,

this device, and arrange to select an appropriate configuration.

This driver implements Ethernet style communication, in one of
|
||||||
|
several ways:
|
||||||
|
|
||||||
|
- The "Communication Device Class" (CDC) Ethernet Control Model.
|
||||||
|
That protocol is often avoided with pure Ethernet adapters, in
|
||||||
|
favor of simpler vendor-specific hardware, but is widely
|
||||||
|
supported by firmware for smart network devices.
|
||||||
|
|
||||||
|
- On hardware can't implement that protocol, a simple CDC subset
|
||||||
|
is used, placing fewer demands on USB.
|
||||||
|
|
||||||
|
- CDC Ethernet Emulation Model (EEM) is a newer standard that has
|
||||||
|
a simpler interface that can be used by more USB hardware.
|
||||||
|
|
||||||
|
RNDIS support is an additional option, more demanding than than
|
||||||
|
subset.
|
||||||
|
|
||||||
|
Within the USB device, this gadget driver exposes a network device
|
||||||
|
"usbX", where X depends on what other networking devices you have.
|
||||||
|
Treat it like a two-node Ethernet link: host, and gadget.
|
||||||
|
|
||||||
|
The Linux-USB host-side "usbnet" driver interoperates with this
|
||||||
|
driver, so that deep I/O queues can be supported. On 2.4 kernels,
|
||||||
|
use "CDCEther" instead, if you're using the CDC option. That CDC

mode should also interoperate with standard CDC Ethernet class

drivers on other host operating systems.

CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM

and therefore can be supported by more hardware. Technically ECM and
|

|
EEM are designed for different applications. The ECM model extends
|
||||||
|
the network interface to the target (e.g. a USB cable modem), and the
|
||||||
|
EEM model is for mobile devices to communicate with hosts using
|
||||||
|
ethernet over USB. For Linux gadgets, however, the interface with
|
||||||
|
the host is the same (a usbX device), so the differences are minimal.
|

If you say "y" here, the Ethernet gadget driver will use the EEM

protocol rather than ECM. If unsure, say "n".

The MIDI Gadget acts as a USB Audio device, with one MIDI

input and one MIDI output. These MIDI jacks appear as

connections can then be made on the gadget system, using
