Subject: [PATCH v2 0/2] Add support for AS7343 multi-spectral sensor
Date: Mon,  7 Sep 2026 14:00:40 -0700	[thread overview]
Message-ID: <20260907210042.32552-1-marcus.yu.56@gmail.com> (raw)

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

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

Testing was performed on a Raspberry Pi 4.

Datasheet: https://look.ams-osram.com/m/5f2d27fff9a874d2/original/AS7343-14-Channel-Multi-Spectral-Sensor.pdf

Changes in v2:
  - Add the LDR, the interrupt pin, and the GPIO pin to the dt bindings.
  - Adjust the default gain to x256 and integration time to 50.1ms as
  recommended by the datasheet.
  - Use read_label instead of .extend
  - Remove all unused scan_index related constants.
