iio: magnetometer: Remove IRQF_ONESHOT

2026-03-04T12:20:55+00:00

[ Upstream commit a54e9440925e6617c98669066b4753c4cdcea8a0 ] Passing IRQF_ONESHOT ensures that the interrupt source is masked until the secondary (threaded) handler is done. If only a primary handler is used then the flag makes no sense because the interrupt can not fire (again) while its handler is running. The flag also disallows force-threading of the primary handler and the irq-core will warn about this. The force-threading functionality is required on PREEMPT_RT because the handler is using locks with can sleep on PREEMPT_RT. Remove IRQF_ONESHOT from irqflags.

iio: magnetometer: yas530: use signed integer type for clamp limits

2024-12-14T18:59:50+00:00

[ Upstream commit f1ee5483e40881d8ad5a63aa148b753b5c6a839b ] In the function yas537_measure() there is a clamp_val() with limits of -BIT(13) and BIT(13) - 1. The input clamp value h[] is of type s32. The BIT() is of type unsigned long integer due to its define in include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but expressed as an unsigned long integer. The size of an unsigned long integer differs between 32-bit and 64-bit architectures. Converting this to type s32 may lead to undesired behavior. Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned long integer divisor BIT(13) causes an unsigned division, shifting the left-hand side of the equation back and forth, possibly ending up in large positive values instead of negative values on 32-bit architectures. To solve those two issues, declare a signed integer with a value of BIT(13). There is another omission in the clamp line: clamp_val() returns a value and it's going nowhere here. Self-assign it to h[i] to make use of the clamp macro. Finally, replace clamp_val() macro by clamp() because after changing the limits from type unsigned long integer to signed integer it's fine that way.

iio: magnetometer: ak8975: Fix reading for ak099xx sensors

2024-10-10T09:57:56+00:00

commit 129464e86c7445a858b790ac2d28d35f58256bbe upstream. Move ST2 reading with overflow handling after measurement data reading. ST2 register read have to be read after read measurment data, because it means end of the reading and realease the lock on the data. Remove ST2 read skip on interrupt based waiting because ST2 required to be read out at and of the axis read.

iio: tmag5273: fix temperature offset

2024-01-01T12:42:38+00:00

commit 3b8157ec4573e304a29b7bced627e144dbc3dfdb upstream. The current offset has the scale already applied to it. The ABI documentation defines the offset parameter as "offset to be added to [Y]_raw prior to scaling by [Y]_scale in order to obtain value in the units as specified in [Y]_raw documentation" The right value is obtained at 0 degrees Celsius by the formula provided in the datasheet: T = Tsens_t0 + (Tadc_t - Tadc_t0) / Tadc_res where: T = 0 degrees Celsius Tsens_t0 (reference temperature) = 25 degrees Celsius Tadc_t0 (16-bit format for Tsens_t0) = 17508 Tadc_res = 60.1 LSB/degree Celsius The resulting offset is 16005.5, which has been truncated to 16005 to provide an integer value with a precision loss smaller than the 1-LSB measurement precision. Fix the offset to apply its value prior to scaling.
