After cheating a bit and pulling the dependency across from my fixes-togreg branch (along with the other patches that were there), I can now apply this. So applied to the fixes-togreg branch of iio.git and pushed out as testing for 0-day to have a quick poke at it before I let this going into linux-next.

The Bosch BMA253 accelerometer is very similar to both BMA254 and BMA255. The current situation is very confusing: BMA254 is supported by the bma180 driver, but BMA255 is supported by the bmc150-accel driver. It turns out the bma180 and bmc150-accel drivers have quite some overlap, and BMA253/BMA254 would be a bit better supported in bmc150-accel (which has support for the motion trigger/interrupt). This series adds BMA253 support to bmc150-accel and also moves BMA254 over to bmc150, removing some unnecessary code from the bma180 driver. In v2 I also sneaked in a small fix for the scale table of BMA222 to simplify backporting for the stable people. --- Changes in v3: - Add new "iio: accel: bmc150: Clarify combo modules in Kconfig" patch - Sort "one-line" chip name lists as well, not just multi-line ones v2: https://lore.kernel.org/linux-iio/20210610122126.50504-1-stephan@gerhold.net/ Changes in v2: - Add new "iio: accel: bmc150: Fix bma222 scale unit" patch at the beginning so the stable people can backport it without conflicts - Add Reviewed-by: from Hans and Andy for all previous patches - Add patch 3 and 4 to have all the chip lists in a consistent order - Fix last patch to also drop BMA254 from the file header in bma180.c v1: https://lore.kernel.org/linux-iio/20210610095300.3613-1-stephan@gerhold.net/ Stephan Gerhold (10): iio: accel: bmc150: Fix bma222 scale unit iio: accel: bmc150: Clarify combo modules in Kconfig iio: accel: bmc150: Drop misleading/duplicate chip identifiers iio: accel: bmc150: Drop duplicated documentation of supported chips iio: accel: bmc150: Sort all chip names alphabetically / by chip ID dt-bindings: iio: accel: bma255: Document bosch,bma253 iio: accel: bmc150: Add device IDs for BMA253 dt-bindings: iio: bma255: Allow multiple interrupts dt-bindings: iio: accel: bma180/bma255: Move bma254 to bma255 schema iio: accel: bma180/bmc150: Move BMA254 to bmc150-accel driver .../bindings/iio/accel/bosch,bma180.yaml | 3 +- .../bindings/iio/accel/bosch,bma255.yaml | 9 +- drivers/iio/accel/Kconfig | 11 ++- drivers/iio/accel/bma180.c | 92 +++---------------- drivers/iio/accel/bmc150-accel-core.c | 87 ++++++------------ drivers/iio/accel/bmc150-accel-i2c.c | 52 +++++------ drivers/iio/accel/bmc150-accel-spi.c | 31 ++++--- drivers/iio/accel/bmc150-accel.h | 10 -- 8 files changed, 98 insertions(+), 197 deletions(-)
