Cover letter [PATCH v7 0/2] Add support for AS7343 multi-spectral sensor
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 v7:
- Specify reg as a const.
- Move additionalProperties after allOf block.
- Clear/set PON during suspend/resume.
- Check for digital saturation before reading spectral data.
Changes in v6:
- Add a ref to leds/common.yaml for the LDR pin in dt bindings.
- Convert ATIME and ASTEP range checks to runtime checks.
- Check for digital saturation before reading spectral data.
Changes in v5:
- Remove the GPIO pin from dt bindings.
- Add autosuspend.
- Start measurements before setting up runtime PM.
Changes in v4:
- Fix led-max-microamp property in dt bindings.
- Use REGCACHE_MAPLE and add volatile table.
- Use PM_RUNTIME_ACQUIRE* when resuming.
Changes in v3:
- Fix gpio description and example in dt.
- Only start measurements after suspend action has been registered.
- Add a mutex and pm_runtime_resume_and_get before reading measurements.
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.
