usb/gadget: Kconfig: fix separate building of configfs-enabled functions
USB_CONFGFS_ZZZZ should appear under a tristate option in order to allow selecting more than one function without building the legacy gadgets. Now there are two problems: 1) they can't be selected at all, because they depend on USB_CONFIGFS, and the patch which adds USB_CONFIGFS has not been merged. 2) they don't select USB_LIBCOMPOSITE (which they need but which is selected by USB_CONFIGFS) Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Acked-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

+config USB_CONFIGFS
+ tristate "USB functions configurable through configfs"
+ select USB_LIBCOMPOSITE
+ help
+ 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.
+ For more information see Documentation/usb/gadget-configfs.txt.

+config USB_CONFIGFS_SERIAL
+ boolean "Generic serial bulk in/out"

+ depends on TTY
+ select USB_U_SERIAL
+ select USB_F_SERIAL
+ help
+ The function talks to the Linux-USB generic serial driver.
+
+config USB_CONFIGFS_ACM
+ boolean "Abstract Control Model (CDC ACM)"
+ depends on USB_CONFIGFS
+ depends on TTY
+ select USB_U_SERIAL
+ select USB_F_ACM
+ help
+ ACM serial link. This function can be used to interoperate with
+ MS-Windows hosts or with the Linux-USB "cdc-acm" driver.

+config USB_CONFIGFS_OBEX
+ boolean "Object Exchange Model (CDC OBEX)"
+ depends on USB_CONFIGFS
+ depends on TTY
+ select USB_U_SERIAL
+ select USB_F_OBEX
+ help
+ You will need a user space OBEX server talking to /dev/ttyGS*,
+ since the kernel itself doesn't implement the OBEX protocol.
+
+config USB_CONFIGFS_NCM
+ boolean "Network Control Model (CDC NCM)"
+ depends on USB_CONFIGFS

+ select USB_U_ETHER

+ NCM is an advanced protocol for Ethernet encapsulation, allows
+ grouping of several ethernet frames into one USB transfer and
+ different alignment possibilities.
+
+config USB_CONFIGFS_ECM
+ boolean "Ethernet Control Model (CDC ECM)"
+ depends on USB_CONFIGFS
+ depends on NET

+ 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.
