Subject: [PATCH v3 0/2] iio: health: max30100: Add DT LED pulse-width support
Date: Sun, 12 Oct 2025 23:00:33 +0530 [thread overview]
Message-ID: <20251012173035.12536-1-raskar.shree97@gmail.com> (raw)
Add Device Tree support for configuring the LED pulse-width of the MAX30100
sensor, and updates the driver to read and apply this property.
Testing:
- Verify DT property read successfully in probe().
- Verify default fallback to 1600 us when DT property is omitted.
- Confirm SPO2_CONFIG register programmed correctly using regmap_read().
- Validate different DT pulse-width values (200, 400, 800, 1600 us)
are applied correctly.
- Validate probe() failure for invalid LED pulse-width
- Tested-on: Raspberry Pi 3B + MAX30100 breakout board
Changelog:
Changes from v2:
- Fix DT binding schema errors
- Add default value
- Remove changelog from commit message
- Add missing header file
