A driver for the MCP-2221 / 2221A multi-io chip. This is a USB to
UART / GPIO / I2C multi-io chip probably based upon a programmed PIC.
The end result is that simple gpio and i2c can exist on any system
that provides a USB port. This is everything from a RPI to a
Virtualbox VM.


o The UART presents itself as a umodem(4) device and pretty much works
as one would expect.

o There are 4 simple GPIO pins with multiple functions that attach to
gpio(4). Support for basic GPIO input and output exists with gpioctl,
the ADC, DAC and clock pulse functions exist as ALT functions. For
the ADC and DAC /dev/ devices are provided such that simple reads and
writes interact with the ADC and DAC. The IRQ function on pin GP1 and
bit banging the GPIO with gpiopps(4) and gpioow(4) are not really
supported. The short answer is that a spin lock is held while trying
to do USB transfers and that isn't allowed.

o There is a simple I2C engine that attaches to iic(4). This mostly
works as expected, except that a READ without STOP is not supported by
the engine which causes problems for some drivers. Most drivers do
not seem to use READ without STOP and seem to work as expected.
Support for changing the I2C speed is not supported, but nothing much
really does that.

o A userland utility called umcpmioctl(8) is provided that allows the
query of the status of the chip and allows for the query of the flash
memory and the setting of some of the flash memory parameters mostly
related to gpio. This utility interacts with a control device in
/dev/. The flash memory contents is copied to the sram on boot up of
the chip and can be used to adjust how the chip sets up the gpio pins,
among other things. Support for setting or entering the chip password
is not provided.

o A number of sysctls are provided to mess with various settings.
These are detailed in the man page.


While not perfect, the chip is reasonable, cheap, and has at least one
vendor making a breakout board. It is also one of the only ones in
this space that has enough documentation to write a driver.

Support for a related chip, the MCP-2210, which provides SPI and GPIO
may exist some day as the programming interface is very simular.

Remove MKCRYPTO option.

Originally, MKCRYPTO was introduced because the United States
classified cryptography as a munition and restricted its export. The
export controls were substantially relaxed fifteen years ago, and are
essentially irrelevant for software with published source code.

In the intervening time, nobody bothered to remove the option after
its motivation -- the US export restriction -- was eliminated. I'm
not aware of any other operating system that has a similar option; I
expect it is mainly out of apathy for churn that we still have it.
Today, cryptography is an essential part of modern computing -- you
can't use the internet responsibly without cryptography.

The position of the TNF board of directors is that TNF makes no
representation that MKCRYPTO=no satisfies any country's cryptography
regulations.

My personal position is that the availability of cryptography is a
basic human right; that any local laws restricting it to a privileged
few are fundamentally immoral; and that it is wrong for developers to
spend effort crippling cryptography to work around such laws.

As proposed on tech-crypto, tech-security, and tech-userlevel to no
objections:

https://mail-index.netbsd.org/tech-userlevel/2017/05/06/msg010547.html

P.S. Reviewing all the uses of MKCRYPTO in src revealed a lot of
*bad* crypto that was conditional on it, e.g. DES in telnet... That
should probably be removed too, but on the grounds that it is bad,
not on the grounds that it is (nominally) crypto.
