o Retrive the part number (CP2103 etc) from the hardware on attach.
o The CP2101 and CP2102 do not support GPIO pin use at all, enforce this.
o Support reading the GPIO status on the second port of the CP2105. More
work is needed before the CP2105 GPIO pins can be used as outputs.

Revert r239178 and implement two new functions, namely
"device_free_softc()" and "device_claim_softc()",
to allow USB serial drivers refcounting the softc.
These functions are used to grab the softc from
auto-free and to free the softc back to the correct
malloc type, respectivly.

Rename command defines to match names used in the datasheet, in order to
make maintaining this driver from the documentation easier in the future.
This is a mostly mechanical change.

In uslcom_param(), move the zeroing of the final two fields of the
flowctrl structure outside of the "if CRTSCTS" section - not only were
they being zeroed in both the clauses, but these two fields have nothing
to do with hardware flow control anyway.

Take advantage of new UCOM and bus functionality so that
the device_detach() function doesn't block on UCOM device
drivers until the TTY handle is closed by the userspace
application. This is implemented by a postpone of the
softc free where the UCOM structures reside until the
TTY references are gone.

Minor style nit:
Use the interface number from the USB interface descriptor
like in the other USB serial drivers. These numbers are not
supposed to be different, though in theory they can. Make sure
that the driver then uses the interface number given by the USB
descriptor, and not the logical index of the USB stack.

For the future:
Whenever the term "index" is used in the USB code, it refers to
a number computed by the USB stack.
Whenever the term "number" is used in the USB code, it refers to
a number in a USB descriptor.

Support multiple interface devices. The driver had previously hardcoded
support for only the first port, but the CP2105 can have multiple ports.
Although this allowed the first port to mostly work on multi port devices,
there could be issues with this arrangement.

Update the man page to reflect support for both ports and the CP2105.

Many thanks to Silicon Labs (www.silabs.com) for providing a CP2105-EK
dev board for testing.

Add support for more devices to uslcom(4). This commit syncronises the
list of supported devices with the union of:

NetBSD src/sys/dev/usb/uslsa.c 1.18
OpenBSD src/sys/dev/usb/uslcom.c 1.24
Linux source/drivers/usb/serial/cp210x.c HEAD

Remove duplicate JABLOTRON PC60B entry.

Note that some of the devices added here are multi-port devices. The
uslcom(4) driver currently only supports the first port on such devices.

Update the man page to reflect the full list of supported devices.
Remove two caveats from the CAVEATS section, as both listed caveats no
longer apply. Add a caveat about multi-port devices.

The baud rate on CP1201/2/3 devices can be set in one of two ways:
- The USLCOM_SET_BAUD_DIV command (0x01)
- The USLCOM_SET_BAUD_RATE command (0x13)

Devices based on the CP1204 will only accept the latter command, and ignore
the former. As the latter command works on all chips that this driver
supports, switch to always using it.

A slight confusion here is that the previously used command was incorrectly
named USLCOM_BAUD_RATE - even though we no longer use it, rename it to
USLCOM_SET_BAUD_DIV to closer match the name used in the datasheet.

This change reflects a similar change made in the Linux driver, which was
submitted by preston.fick at silabs.com, and has been tested on all of the
uslcom(4) devices I have to hand.

- This patch adds custom IOCTLs to read and write the 4 GPIO pins on the
cp2103 usb-to-serial chip.
- This patch also makes the line status polling asynchronous, to reduce

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of

reason why it shouldn't be static.

- make usb2_power_mask_t 16-bit

"usb2_config" has a new field called "usb_mode" which select for which mode
the current xfer entry is active. Options are: a) Device mode only b) Host
mode only (default-by-zero) c) Both modes. This change was scripted using
the following sed script: "s/\.mh\././g".
- the standard packet size table in "usb_transfer.c" is now a function, hence
the code for the function uses less memory than the table itself.
