The CNS3XXX SOC has include USB EHCI and OHCI compatible controllers. This patch adds the necessary glue logic to allow ehci-hcd and ohci-hcd drivers to work on CNS3XXX The EHCI and OHCI controllers share a common clock control and reset bit, therefore additional check for the timming of enabling and disabling is required. The USB bit of PLL Power Down Control is also shared by OTG, 24MHzUART clock, Crypto clock, PCIe reference clock, and Clock Scale Generator. Therefore we only ensure it is enabled, while not disabling it.

|
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.txt>.

|
|
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.
