The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
SPI device registered via OF will always match a legacy SPI device ID and
that the MODALIAS reported will always be of the form spi:<device>.
There is an ACPI method to enumerate such devices via specific ACPI ID
and use of compatible strings. It will not work for the drivers which
have no OF match ID table present.
Besides this could change in the future so the correct approach is to
have an OF device ID table if the devices are registered via OF.

STM32 ADC allows each channel to be sampled with a different sampling time,
by setting SMPR registers. Basically, value depends on local electrical
properties. Selecting correct value for sampling time highly depends on
analog source impedance. There is a manual that may help in this process:
'How to get the best ADC accuracy in STM32...'
This patch allows to configure minimum sampling time via device tree,
either for:
- all channels at once:
st,min-sample-time-nsecs = <10000>;
- independently for each channel (must match "st,adc-channels" list):
st,adc-channels = <0 1>;
st,min-sample-time-nsecs = <5000 10000>;

4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)

Add support for CCS811 VOC sensor. This patch adds support
for reading current and voltage across the sensor and TVOC
and equivalent CO2 values.
Scale and offset values have been computed according to datasheet:
- For current: raw value is in microamps
=> 0.001 scale to convert to milliamps
- For voltage: 1.65V = 1023, therefore 1650mV = 1023
=> 1650.0/1023 = 1.612903 scale to convert to millivolts
- For eCO2: raw value range is from 400ppm to 8192ppm.
=> (val - 400) * (100 - 0) / (8192 - 400) + 0 =
(val - 400) * 0.01283367 => offset: -400, scale = 0.012834
to get a percentage value
-For TVOC: raw value range is from 0ppb to 1187ppb.
=> (val - 0) * 100 / (1187 - 0) + 0 = val * 0.0842459 =>
scale = 0.084246 for getting a percentage value

Here is the "big" char/misc driver patchset for 4.13-rc1.
Lots of stuff in here, a large thunderbolt update, w1 driver header
reorg, the new mux driver subsystem, google firmware driver updates, and
a raft of other smaller things. Full details in the shortlog.
All of these have been in linux-next for a while with the only reported
issue being a merge problem with this tree and the jc-docs tree in the
w1 documentation area. The fix should be obvious for what to do when it
happens, if not, we can send a follow-up patch for it afterward.

Some part of the configuration are not touched after the probe
and if something goes wrong on writing the initial one,
the chip will misbehave.
Adding an error checking ensures that the inital configuration will
be written correctly. Moreover ensures that a sensible configuration
will be saved in driver data and used subsequently as intended.
