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>

-config USB_ZERO
- tristate "Gadget Zero (DEVELOPMENT)"
- select USB_LIBCOMPOSITE
- select USB_F_SS_LB
- help
- 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.
-
- Say "y" to link the driver statically, or "m" to build a
- dynamically linked module called "g_zero".

-config USB_ZERO_HNPTEST

- help
- You can configure this device to enumerate using the device
- identifiers of the USB-OTG test device. That means that when
- this gadget connects to another OTG device, with this one using
- the "B-Peripheral" role, that device will use HNP to let this
- one serve as the USB host instead (in the "B-Host" role).

-config USB_AUDIO

- help
- This Gadget Audio driver is compatible with USB Audio Class
- specification 2.0. It implements 1 AudioControl interface,
- 1 AudioStreaming Interface each for USB-OUT and USB-IN.
- Number of channels, sample rate and sample size can be
- specified as module parameters.
- This driver doesn't expect any real Audio codec to be present
- on the device - the audio streams are simply sinked to and
- sourced from a virtual ALSA sound card created. The user-space
- application may choose to do whatever it wants with the data
- received from the USB Host and choose to provide whatever it
- wants as audio data to the USB Host.

- depends on NET
- select USB_LIBCOMPOSITE
- select USB_U_ETHER
- select USB_F_ECM
- select USB_F_SUBSET
- select CRC32
- help
- 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.
-
- Say "y" to link the driver statically, or "m" to build a
- dynamically linked module called "g_ether".
-
-config USB_ETH_RNDIS
- bool "RNDIS support"
- depends on USB_ETH
- select USB_LIBCOMPOSITE
- select USB_F_RNDIS
- default y
- help
- Microsoft Windows XP bundles the "Remote NDIS" (RNDIS) protocol,
- and Microsoft provides redistributable binary RNDIS drivers for
- older versions of Windows.
-
- If you say "y" here, the Ethernet gadget driver will try to provide
- a second device configuration, supporting RNDIS to talk to such
- Microsoft USB hosts.
-
- To make MS-Windows work with this, use Documentation/usb/linux.inf
- as the "driver info file". For versions of MS-Windows older than
- XP, you'll need to download drivers from Microsoft's website; a URL
- is given in comments found in that info file.
-
-config USB_ETH_EEM
- bool "Ethernet Emulation Model (EEM) support"
- depends on USB_ETH
- select USB_LIBCOMPOSITE
- select USB_F_EEM
- default n
- help
- 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".

- This driver supports a CDC-ACM module option, which can be used
- to interoperate with MS-Windows hosts or with the Linux-USB
- "cdc-acm" driver.
