KX023-1025 [1] is another accelerometer from Kionix that has lots
of additional functionality compared to KXCJK-1013. It combines the
motion interrupt functionality from KXCJK with the tap detection
from KXTF9, plus a lot more other functionality.
This patch set does not add support for any of the extra functionality,
but makes basic functionality work with the existing kxcjk-1013 driver.
At first, the register map for the KX023-1025 seems quite different
from the other accelerometers supported by the kxcjk-1013.
However, it turns out that at least most of the register bits
still mean the same for KX023-1025.
This patch set refactors the kxcjk-1013 driver a little bit
to get the register addresses from a chip-specific struct.
The register bits can be re-used for all the different chips.
The KX023-1025 is used in several smartphones from Huawei.
I tested these changes on a Huawei Ascend G7, someone else reported
they also work fine on the Huawei Honor 5X (codename "kiwi").
