IIO: 2nd set of fixes for the 7.1 cycle. Usual mixed bag of ancient issues and the recently introduced. Various drivers - Ensure use of simple_write_to_buffer() in debugfs callbacks doesn't result in reading off the end of intended data by checking the position is always 0. buffer/hw-consumer - Ensure scan_mask is freed on buffer release. acpi-als - Check ACPI_COMPANION() against NULL to close corner case where a driver is overridden. adi,ad4062 - Add GPIOLIB dependency to avoid undefined ref to gpiochip_get_data() adi.ad7768-1 - Add GPIOLIB dependency to avoid several undefined functions. adi,ad2s1210 - Ensure possible recovery path if a read fails in the interrupt handler. bosch,bmg160 - Increase sleep on startup to ensure device is ready. bosch,bmp280 - Ensure buffer pushed to kfifo is zeroed to avoid leaking uninitialized stack data to userspace. dyna-image,al3010 - Fix refactor that stopped reading one of the two measurement registers. dyna-image,al3320a - Fix refactor that stopped reading one of the two measurement registers. qcom,spmi-iadc - Ensure disable_irq_wake() is called on remove path. sensiron,scd30 - Fix a sign extension bug. st,vl5310x - Ensure possible recovery path if a read fails in the interrupt handler. ti,adc1298 - Bounds check for pga_settings index. Hardening against device returning unexpected values. ti,tmp006 - Ensure trigger correctly released on remove path. vishay,veml6030 - Fix incorrect channel type in events. vishay,veml6074 - Bounds check for veml6075_it_ms.

iio: light: tsl2591: remove unneeded tsl2591_compatible_als_persist_cycle()

2026-06-03T11:10:56+00:00

The function was only used to verify if als_persist is a TSL2591_PRST_ALS_INT_CYCLE_* value. However, before its call in tsl2591_write_event_value(), the line als_persist = tsl2591_persist_lit_to_cycle(period) is executed, meaning that by the time tsl2591_compatible_als_persist_cycle() is reached, als_persist is a TSL2591_PRST_ALS_INT_CYCLE_* value, making the verification pointless.

iio: light: veml3328: add support for new device

2026-06-02T13:03:20+00:00

Add support for the Vishay VEML3328 RGB/IR light sensor communicating via I2C (SMBus compatible). Also add a new entry for said driver into Kconfig and Makefile. Assisted-by: Gemini:3.1-Pro Signed-off-by: Joshua Crofts Signed-off-by: Jonathan Cameron

light: tsl2591: simplify tsl2591_persist functions via lookup table

2026-05-31T10:01:51+00:00

Replace switch statements with an indexed lookup table for persist cycle conversions. Both functions contain redundant switch statements. This reduces code duplication and makes future updates to TSL2591_PRST_ALS_INT_CYCLE_* definitions easier to maintain by keeping the mapping in a single place.

iio: light: add support for APDS9999 sensor

2026-05-31T10:01:49+00:00

Add IIO driver for Broadcom APDS9999 ambient light sensor. The APDS9999 is a digital proximity and RGB sensor with ALS capability. The driver implements the ALS/Lux functionality using the green channel, which uses optical coating technology to approximate the human eye spectral response. Raw IIO_INTENSITY channels are exposed for red, green, blue, and IR so userspace can compute its own weighted lux. Proximity (PS) support is not yet implemented. Signed-off-by: Jose A.

iio: light: cros_ec_light_prox: simplify timestamp channel definition

2026-05-31T10:01:49+00:00

Use IIO_CHAN_SOFT_TIMESTAMP() to define the timestamp channel instead of manually filling in the struct iio_chan_spec fields. This makes the code less verbose and mistake-prone. Also drop obvious comment while we're at it. Signed-off-by: David Lechner Signed-off-by: Jonathan Cameron

iio: tcs3472: move standalone return to default case

2026-05-31T10:01:48+00:00

Move the trailing 'return -EINVAL' statements at the end of tcs3472_read_raw() and tcs3472_write_raw() into explicit default: cases inside the respective switch statements. This removes the need for a separate return statement after the switch. No functional change.

iio: tcs3472: use local struct device * for remaining cases

2026-05-31T10:01:48+00:00

Use the local 'struct device *dev' variable introduced for the devm calls also for the dev_info() calls in tcs3472_probe(), to keep the probe function consistent. No functional change. Signed-off-by: Aldo Conte Signed-off-by: Jonathan Cameron

iio: tcs3472: use devm for resource management

2026-05-31T10:01:48+00:00

Convert the driver to use device-managed resource allocation: - Add tcs3472_powerdown_action() and register it with devm_add_action_or_reset() to ensure the device is powered down on cleanup. - Replace iio_triggered_buffer_setup() with devm_iio_triggered_buffer_setup(). - Replace request_threaded_irq() with devm_request_threaded_irq(). - Replace iio_device_register() with devm_iio_device_register(). - Replace mutex_init() with devm_mutex_init(). - Remove tcs3472_remove() as all cleanup is now handled by devm. Use a local 'dev = &client->dev' in tcs3472_probe() to keep the devm calls compact. Signed-off-by: Aldo Conte Signed-off-by: Jonathan Cameron
