This fixes several errors in the offset and scaling of the raw values from the KXSD9 sensor: - The code did not convert the big endian value from the sensor into the endianness of the host CPU. Fix this with be16_to_cpu() on the raw obtained value. - The code did not regard the fact that only the upper 12 bits of the accelerometer values are valid. Shift these down four bits to yield the real raw value. - Further the sensor provides 2048 at zero g. This means that an offset of 2048 must be subtracted from the raw value before scaling. This was not taken into account by the driver, yielding a weird value. Fix this by providing this offset in sysfs. To house the scaling code better, the value reading code was factored into the raw reading function. This proper scaling and offseting is necessary to get proper values out of triggered buffer by offsetting, shifting and scaling them. Signed-off-by:

This converts the KXSD9 driver to drop the custom transport mechanism and just use regmap like everything else. Tested-by:

This moves the KXSD9 SPI transport out to its own file and Kconfig entry, so that we will be able to add another transport method. We export the common probe and add a local header file for the functionality shared between the main driver and the transport driver. We make the SPI transport the default for the driver if SPI is available and the KXSD9 driver was selected, so the oldconfig upgrade path will be clear. Signed-off-by:

This makes it possible to later split the transport mechanism using a generic probe() and a generic remove(). Use dev_set_drvdata() and dev_get_drvdata() as a paired accessor to operate on the abstract struct device * regardless of the transport mechanism in use. Signed-off-by:
