iio: pressure: mprls0025pa: fix scan_type struct

2026-03-04T12:20:10+00:00

[ Upstream commit 8a228e036926f7e57421d750c3724e63f11b808a ] Fix the scan_type sign and realbits assignment. The pressure is a 24bit unsigned int between output_min and output_max. transfer function A: 10% to 90% of 2^24 transfer function B: 2.5% to 22.5% of 2^24 transfer function C: 20% to 80% of 2^24 [MPR_FUNCTION_A] = { .output_min = 1677722, .output_max = 15099494 } [MPR_FUNCTION_B] = { .output_min = 419430, .output_max = 3774874 } [MPR_FUNCTION_C] = { .output_min = 3355443, .output_max = 13421773 } Fixes: 713337d9143e ("iio: pressure: Honeywell mprls0025pa pressure sensor") Signed-off-by: Petre Rodan Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron Signed-off-by: Sasha Levin

iio: pressure: mprls0025pa: use aligned_s64 for timestamp

2025-09-09T16:56:30+00:00

[ Upstream commit ffcd19e9f4cca0c8f9e23e88f968711acefbb37b ] Follow the pattern of other drivers and use aligned_s64 for the timestamp. This will ensure the struct itself it also 8-byte aligned. While touching this, convert struct mpr_chan to an anonymous struct to consolidate the code a bit to make it easier for future readers.

iio: pressure: bmp280: Use IS_ERR() in bmp280_common_probe()

2025-08-28T14:28:45+00:00

commit 43c0f6456f801181a80b73d95def0e0fd134e1cc upstream. `devm_gpiod_get_optional()` may return non-NULL error pointer on failure. Check its return value using `IS_ERR()` and propagate the error if necessary.

iio: pressure: zpa2326: Use aligned_s64 for the timestamp

[ Upstream commit 886a446b76afddfad307488e95e87f23a08ffd51 ] On x86_32 s64 fields are only 32-bit aligned. Hence force the alignment of the field and padding in the structure by using aligned_s64 instead.

iio: pressure: zpa2326: fix information leak in triggered buffer

2025-01-17T12:36:23+00:00

commit 6007d10c5262f6f71479627c1216899ea7f09073 upstream. The 'sample' local struct is used to push data to user space from a triggered buffer, but it has a hole between the temperature and the timestamp (u32 pressure, u16 temperature, GAP, u64 timestamp). This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

iio: pressure: bmp280: Fix waiting time for BMP3xx configuration

2024-10-10T09:58:05+00:00

[ Upstream commit 262a6634bcc4f0c1c53d13aa89882909f281a6aa ] According to the datasheet, both pressure and temperature can go up to oversampling x32. With this option, the maximum measurement time is not 80ms (this is for press x32 and temp x2), but it is 130ms nominal (calculated from table 3.9.2) and since most of the maximum values are around +15%, it is configured to 150ms.
