Samples are buffered in a 32-entry hardware FIFO with a configurable almost-full interrupt. This series adds a DT binding schema, an IIO triggered-buffer driver, and a MAINTAINERS entry. Changes in v6: - dt-bindings: remove "SoC" from description (Jonathan Cameron) - dt-bindings: spell out PPG and ECG acronyms in full before abbreviating them (Jonathan Cameron) - dt-bindings: remove the I2C 400 kHz sentence from description; keep FIFO/interrupt mention (Jonathan Cameron) - dt-bindings: simplify interrupt description to FIFO almost-full only Changes in v5: - dt-bindings: remove avdd-supply from required[] (Krzysztof Kozlowski) - dt-bindings: rename leds-supply to vled-supply (Krzysztof Kozlowski) - dt-bindings: remove literal block scalar from interrupts description (Krzysztof Kozlowski) - dt-bindings: use IRQ_TYPE_LEVEL_LOW in example (Sashiko AI review) Changes in v4: - driver: fix buffer overflow: buf[4] -> buf[6] for full sample - driver: use iio_device_claim_direct() for raw reads - driver: add OVF_COUNTER FIFO-full detection - driver: fix active_scan_mask channel packing - driver: remove IRQF_ONESHOT (threaded IRQ already implies it) - driver: add set_trigger_state callback - driver: use IIO_CPU endianness for timestamp - driver: use devm for powerdown on remove - driver: enable regulator before first access - driver: use devm action for iio_trigger_put Md Shofiqul Islam (3): dt-bindings: iio: health: add adi,max86150 iio: health: add MAX86150 ECG and PPG biosensor driver MAINTAINERS: add entry for MAX86150 IIO health driver .../bindings/iio/health/adi,max86150.yaml | 70 ++ MAINTAINERS | 7 + drivers/iio/health/Kconfig | 23 + drivers/iio/health/Makefile | 1 + drivers/iio/health/max86150.c | 725 ++++++++++++++++++ 5 files changed, 826 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/health/adi,max86150.yaml create mode 100644 drivers/iio/health/max86150.c -- 2.51.1
