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 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
