This patch series introduces support for ROHM KX134ACR-LBZ and KX134-1211 accelerometers. The KX134ACR-LBZ is almost identical to the KX132ACR-LBZ. Similarly the KX134-1211 is almost identical to the KX132-1211. The differencies visible to the driver are different g-ranges and the "Who am I" -identification register's values. This series does also convert parts of the GTS helpers and the kx022a driver to use __cleanup - based scoped free/unlock operations, and fixes the value of required wait time after sensor reset. The wait time value fixup is cosmetic/documentational, as the time that has been slept has likely been larger than required due to the msleep() implementation. Revision history: v1 => v2: - Rebased on iio-fixes to avoid conflicts with queued fixes. - Added the reset delay change to the series to avoid conflicts. Was previously sent as an individual patch: https://lore.kernel.org/all/ZzWfXbjaDkFnu_Jg@mva-rohm/ - Added support for kx134-1211 The v1 can be found from: https://lore.kernel.org/all/cover.1731495937.git.mazziesa... The patch 1/8 is the delay fixup mentioned above. The patch 2/8 contains GTS helper change, which is independent from the rest of the series. It can be applied/rejected independently. Patch 3/8 changes kx022a to use scoped mutexes. It can also be applied as an independent improvement even if the kx134acr-lbz support was not added. Patch 4/8 adds mechanisms for supporting sensors with different g-ranges in the kx022a driver. 5-8/8 add support for new hardware, kx134acr-lbz and kx134-1211. --- Matti Vaittinen (8): iio: accel: kx022a: Improve reset delay iio: gts: Simplify using __free iio: accel: kx022a: Use cleanup.h helpers iio: accel: kx022a: Support ICs with different G-ranges dt-bindings: ROHM KX134ACR-LBZ iio: kx022a: Support ROHM KX134ACR-LBZ dt-bindings: iio: kx022a: Support KX134-1211 iio: accel: kx022a: Support KX134-1211 .../bindings/iio/accel/kionix,kx022a.yaml | 11 +- drivers/iio/accel/kionix-kx022a-i2c.c | 4 + drivers/iio/accel/kionix-kx022a-spi.c | 4 + drivers/iio/accel/kionix-kx022a.c | 170 ++++++++++++------ drivers/iio/accel/kionix-kx022a.h | 6 + drivers/iio/industrialio-gts-helper.c | 19 +- 6 files changed, 147 insertions(+), 67 deletions(-) -- 2.47.0
