      iio: 104-quad-8: Add IIO support for the ACCES 104-QUAD-8 · 28e5d3bb
      William Breathitt Gray authored 
      The ACCES 104-QUAD-8 is a general purpose quadrature encoder
counter/interface board. The 104-QUAD-8 is capable of monitoring the
outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit
dual-axis quadrature counter chips. Core functions handled by the
LS7266R1, such as direction and total count, are available.

Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and
also clears the counter's respective error flag. Although the counters
have a 25-bit range, only the lower 24 bits may be set, either directly
or via a counter's preset attribute. Interrupts are not supported by
this driver.

This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES
104-QUAD-4. The base port addresses for the devices may be configured
via the base array module parameter.

      iio: Implement counter channel type and info constants · 1a8f324a
      William Breathitt Gray authored 
      Quadrature encoders, such as rotary encoders and linear encoders, are
devices which are capable of encoding the relative position and
direction of motion of a shaft. This patch introduces several IIO
constants for supporting quadrature encoder counter devices.

  IIO_COUNT: Current count (main data provided by the counter device)
  IIO_INDEX: Counter device index value

      iio: pressure: Add driver for Honeywell ABP family · 9ecca12e
      Marcin Malagowski authored 
      This patch adds minimal driver for the Honeywell Amplified Basic
Pressure sensors series. Sensors are pretty simple but are
available in many variants:
- psi/mbar/kPa output,
- analog/i2c/spi,
- gage/differential measurement,
- different measure ranges etc.

Refer to datasheets for more details:
http://sensing.honeywell.com/honeywell-sensing-basic-board-mount-pressure-sensors-abp-series-datasheet-323005128-c-en.pdf
http://sensing.honeywell.com/index.php%3Fci_id%3D45841

Driver internals:
- i2c only. measure request is done by the SMBUS QUICK cmd, so if the i2c
  bus doesn't support it, it is required to send a dummy byte to trigger
  measurement,
- since iio sysfs expects kilopascals, mbar-variants are treated as their
  respective kPa-s, hence i2c id-table has doubled entries in one line:
	{ "abp060mg", ABP006KG }, { "abp006kg", ABP006KG },
- psi-variants have prescaled values in config,
- no temperature reads yet.

Work remained:
- optional temperature channel,
- SPI support,
- DT binding.

Changes since v1:
- mutex is now locked in read_raw(),
- corrected error codes,
- fixed coding style issues,
- renamed few defines and functions abp -> abp060mg
(some structs left as they were to keep the sensible meaning).
