This patch series adds support for the
ENS210/ENS210A/ENS211/ENS212/ENS213A/ENS215 temperature and humidity
sensors.

Patch 1 adds the required device tree bindings.

Patch 2 adds the driver, providing the probe and read functions.

Signed-off-by: Joshua Felmeden <jfelmeden@thegoodpenguin.co.uk>

changelog v1 -> v2:
sciosense,ens21x.yaml: Add supply to documentation
sciosense,ens21x.yaml: Add fallback to compatible strings
ens21x.c: Move i2c_device_id next to of_device_id
ens21x.c: Use i2c_of_match_device() instead of of_match_device()

Many thanks for taking the time to review my patch.

Thanks,
Josh

- General: Changed wildcard ens21x to ens210 to avoid wildcards
- Kconfig: added crc7 as a dependency
- Kconfig: remove extra blank lines
- ens210.c: Moved constants to inline
- ens210.c: Created ens210 chip info to handle chip specific conversion
- ens210.c: Added documentation for mutex
- ens210.c: Fixed sparse complaints from kernel bot
- ens210.c: Changed htonl to cpu_to_be32
- ens210.c: Renamed dev_data -> ens210_data
- ens210.c: changed of_match to i2c
- ens210.c: Added return check for i2c write
- ens210.c: Removed switch for conversion check, use chip_info instead
- ens210.c: Removed unnecessary retry loop
- ens210.c: Convert read to u8[3] type
- ens210.c: Ensure 'correct' path is inline, use early returns to break
    for errors
- ens210.c: Changed mutex to scoped_guard
- ens210.c: Changed part id mismatch to dev_info from dev_err and removed
    return
- ens210.c: Moved name from id->name to chip_info
- ens210.c: Changed data field to be chip_info rather than enum
- ens210.c: Formatting fixes (consistent spacing, extra line break at end
    removed)
