iio: Use IRQF_NO_THREAD

2026-03-04T12:20:37Z

[ Upstream commit 04d390af97f2c28166f7ddfe1a6bda622e3a4766 ] The interrupt handler iio_trigger_generic_data_rdy_poll() will invoke other interrupt handler and this supposed to happen from within the hardirq. Use IRQF_NO_THREAD to forbid forced-threading. Signed-off-by: Sebastian Andrzej Siewior Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron Signed-off-by: Sasha Levin

iio: accel: bma180: use stack allocated buffer for scan

2025-08-16T10:57:05Z

Move the scan struct to the stack instead of being in the driver state struct. The buffer is only used in a single function and does not need to be DMA-safe so it does not need to exist outside of that function's scope.

iio: Remove unused macro definition for driver and IRQ name

These macro definitions are completely unused. Remove them. Signed-off-by: Waqar Hameed Link: https://patch.msgid.link/0dec4fe7b2bdc90d06163ac75a53b97d4ae31c21.1748356671.git.waqar.hameed@axis.com Signed-off-by: Jonathan Cameron

iio: accel: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

2025-05-21T13:20:26Z

This new function allows us to perform debug checks in the helper to ensure that the overrun does not occur. Use it in all the simple cases where either a static buffer or a structure is used in the drivers.

iio: accel: Switch to sparse friendly iio_device_claim/release_direct()

2025-03-04T13:17:48Z

Single patch for the simple cases in accelerometer drivers. These new functions allow sparse to find failures to release direct mode reducing chances of bugs over the claim_direct_mode() functions that are deprecated.

iio: accel: bma180: Convert enum->pointer for data in the match table

2023-09-11T19:12:42Z

Convert enum->pointer for data in the match table, so that device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c bus type match support added to it. Replace enum->struct *bma180_part_info for data in the match table and simplify bma180_probe().

iio: adc: Explicitly include correct DT includes

2023-07-23T12:38:13Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
