[PATCH 0/2] Add support for AS7343 multi-spectral sensor

Posted by Chang Yu 2 weeks, 6 days ago

This series adds initial support for the AMS AS7343 14-channel
multi-spectral sensor.

The sensor has 14 optical channels (11 visible + NIR + clear +
flicker) in total. This initial driver supports reading raw counts
from all 12 spectral channels (11 visible + NIR) via sysfs and basic
power management.

Not yet supported:
- Configurable integration time and gain
- Interrupt support
- Clear (VIS) channel and flicker detection

The driver uses `extend_name` to differentiate channels, exposing
files like in_intensity_F1_raw for channel F1, etc. via sysfs.

Patch 1 adds device tree bindings.
Patch 2 adds the driver.

Testing was performed on a Raspberry Pi 4.

This is a Datasheet link, no need to have three lines for it, just

In addition to this I'd like to see the tag in the driver commit tag
block. That is more useful than having it in the cover letter. 

Thanks,
