The Faraday FOTG210 is a dual-mode OTG USB controller that can act as host, peripheral or both. To be able to probe from one hardware description and to follow the pattern of other dual- mode controllers such as MUSB or MTU3 we need to collect the two, currently completely separate drivers in the same directory. After this, users need to select the main symbol USB_FOTG210 and then each respective subdriver. We pave the road to compile both drivers into the same kernel and select the one we want to use at probe() time, and possibly add OTG support in the end. This patch doesn't do much more than create the new symbol and collect the drivers in one place. We also add a comment for the section of dual-mode controllers in the Kconfig file so people can see what these selections are about. Also add myself as maintainer as there has been little response on my patches to these drivers.

Universal Serial Bus (USB) is a specification for a serial bus
|
|
subsystem which offers higher speeds and more features than the
|
|
traditional PC serial port. The bus supplies power to peripherals
|
|
and allows for hot swapping. Up to 127 USB peripherals can be
|
|
connected to a single USB host in a tree structure.
|
|
|
|
The USB host is the root of the tree, the peripherals are the
|
|
leaves and the inner nodes are special USB devices called hubs.
|
|
Most PCs now have USB host ports, used to connect peripherals
|
|
such as scanners, keyboards, mice, modems, cameras, disks,
|
|
flash memory, network links, and printers to the PC.
|
|
|
|
Say Y here if your computer has a host-side USB port and you want
|
|
to use USB devices. You then need to say Y to at least one of the
|
|
Host Controller Driver (HCD) options below. Choose a USB 1.1
|
|
controller, such as "UHCI HCD support" or "OHCI HCD support",
|
|
and "EHCI HCD (USB 2.0) support" except for older systems that
|
|
do not have USB 2.0 support. It doesn't normally hurt to select
|
|
them all if you are not certain.
|
|
|
|
If your system has a device-side USB port, used in the peripheral
|
|
side of the USB protocol, see the "USB Gadget" framework instead.
|
|
|
|
After choosing your HCD, then select drivers for the USB peripherals
|
|
you'll be using. You may want to check out the information provided
|
|
in <file:Documentation/usb/> and especially the links given in
|
|
<file:Documentation/usb/usb-help.rst>.

This driver is for USB parallel port adapters that use the Lucent
|
|
Technologies USS-720 chip. These cables are plugged into your USB
|
|
port and provide USB compatibility to peripherals designed with
|
|
parallel port interfaces.
|
|
|
|
The chip has two modes: automatic mode and manual mode. In automatic
|
|
mode, it looks to the computer like a standard USB printer. Only
|
|
printers may be connected to the USS-720 in this mode. The generic
|
|
USB printer driver ("USB Printer support", above) may be used in
|
|
that mode, and you can say N here if you want to use the chip only
|
|
in this mode.
|
|
|
|
Manual mode is not limited to printers, any parallel port
|
|
device should work. This driver utilizes manual mode.
|
|
Note however that some operations are three orders of magnitude
|
|
slower than on a PCI/ISA Parallel Port, so timing critical
|
|
applications might not work.
|
|
|
|
Say Y here if you own an USS-720 USB->Parport cable and intend to
|
|
connect anything other than a printer to it.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called uss720.
