A driver for the DS28E17 1-Wire to I2C bridge chip.

This chip acts like a 1-Wire slave device and provides a iic(4) master
at the end of the 1-Wire bus. More or less it is the polar opposite
of the DS2482 [ds2482ow(4)] chip.

This device couples well with ds2482ow(4) and can be used to provide a
I2C bus at very great lengths from the controlling computer.

All features of the chip are supported, except for 1-Wire overdrive
support, which requires more work from the onewire(4) infrastructure.

The chip does not support Read without Stop. Attempts to do this will
get turned into a Read with Stop and one will have to hope for the
best. The chip also does not support zero length I2C reads or zero
length I2C writes. This has the side effect of making the default
mode, a zero length I2C write, for i2scan(8) return false positives.
The alternative mode that i2cscan(8) can use, the single byte read,
should work as expected.

The chip has automatic support for end devices that do I2C clock
stretching.

It was noticed that this chip does not work with the gpioow(4) driver.
That might be an interesting thing to debug if one has a good logic
analyzer on hand. While the presence pulse is detected, the gpioow(4)
driver is not able to complete the initial ROM enumeration. The
DS28E17 works flawlessly when driven by a DS2482 [ds2482ow(4)] driver
chip. Poke me if you want any more details.

The chip is pretty inexpensive and only requires a single cap to get
it hooked up. However, the package it comes in is only a 16-QFN
package, so it could provide to be hard to solider onto a board for
some. There are side tabs, so it was possible with a very small iron
and lots of flux. There is a slightly expensive breakout board sold
by Mikroe that probably works well -> https://www.mikroe.com/1-wire-i2c-click

A driver for the Bosch BMP280 / BME280 temperature, humidity and
atmospheric pressure sensor. This is an inexpensive to moderately
expensive chip available from a large number of places. The driver
supports all aspects of the two chips, except for the repeating read
mode which would allow for sub-second queries, such as fall detection
or perhaps even as an altimeter. This driver also only supports the
I2C interface and not the SPI interface.

The BME280, the one with humidity, is not fully tested at this point,
awaiting upon a breakout board and may not show proper humidity.

can be both built-in and part of a loaded module (eg, piixpm is in

A driver and user land utility for the Sparkfun Serial Controlled Motor
Driver module as illustrated here:

https://www.sparkfun.com/products/13911

A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.

The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

This is a moderately priced gas sensor that can detect volatile
organic compounds in the air. The driver uses the 3-clause BSD
licensed VOC algorithm provided by Sensirion to turn the raw sensor
metric into a VOC index which can indicate the quality of the air in a
particular indoor environment. All published functions of the chip
are supported and one unpublished feature.
