During msa311 accel IIO driver development https://lore.kernel.org/linux-iio/20220616104211.9257-1-ddrokosov@xxxxxxxxxxxxxx/ Andy requested to use proper units in the hz->ms calculation. Current units.h header doesn't have milli, micro and nano HZ coefficients, so some drivers (in the IIO subsystem) implement their own copies for that. The current patchset resolves such a problem and intoduces general MILLIHZ_PER_HZ, UHZ_PER_HZ and NHZ_PER_HZ definitions in the units.h, and fixes all drivers which duplicate these units. Changes v1->v2: - changed MHZ_PER_HZ to a different name as Andy suggested (suppose MILLIHZ_PER_HZ is good enough) Dmitry Rokosov (3): units: complement the set of Hz units iio: accel: adxl345: use HZ macro from units.h iio: common: scmi_sensors: use HZ macro from units.h drivers/iio/accel/adxl345_core.c | 2 +- drivers/iio/common/scmi_sensors/scmi_iio.c | 2 +- include/linux/units.h | 3 +++ 3 files changed, 5 insertions(+), 2 deletions(-) -- 2.36.0
