2dd990ad55 drivers: sensor: ccs811: enable drive mode 4
This mode is documented as producing a raw result every 250 ms that the
application must convert to eCO2 and eTVOC readings.  In practice
application firmware 2.0 appears to convert the readings as with all
other rates.

403a7ab2c5 drivers: sensor: ccs811: support triggers
Add the standard suite of trigger configuration options.  Add driver
support for the DATA_READY and THRESHOLD triggers.  Note cross-module
dependency as configuring the trigger requires a controlled modification
of the sensor registers and the sensor driver API doesn't support this.

59d41669b9 drivers: sensor: ccs811: make measurement drive mode configurable
Allow application to choose the measurement rate.

Measurement mode 4 (250 ms rate) is not supported because it we have no
support for processing the raw data it produces.

819276e082 sensor: ccs811: Convert GPIOs to device tree
Update ccs811 dts binding to include GPIO pins for wakeup, reset, and
interrupt and change driver code to get the GPIO pin and controller
info from DT instead of Kconfig.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

    git ls-files '*Kconfig*' | \
        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

75bc6ba454 drivers: boards: Merge HAS_DTS_I2C_DEVICE with HAS_DTS_I2C
Every board that uses dts-enabled i2c drivers has a board-level dts, so
there is no need to have separate configs HAS_DTS_I2C_DEVICE and
HAS_DTS_I2C.

ab9017ec83 sensor: Eliminate repetitive Kconfig "depends on" in sensor drivers
For each sensor driver, wrap all Kconfig symbols in a big if/endif
conditional rather than repeating "depends on" for each symbol.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

19d7803546 drivers: sensor: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Add support for AMS CCS811 Digital Gas Sensor for monitoring
indoor air quality. This sensor reports the following parameters:

1. Co2 concentration
2. VOC concentration
3. Sensor voltage
4. Sensor current

This driver only supports polling mode as of now.
