KXTF9 has mostly compatible register layout to KXCJK accelerometer. There is no motion direction interrupt support, but there is tap direction detection instead (not implemented in this patch).

A minor point inline where you are using the or of two bits when GENMASK is more appropriate.

I am sure it will break some boards. We have some boards with an interface called SFI, which can send this platform data.

Rename kxcjk-1013 driver by removing -1013 suffix. '1013' is a variation specifier only (eg. different voltage) as can be seen in datasheet for eg. KXTF9 parts.

Old name is left as an modules's alias. Should not matter, though, for distros using proper module loading based on device name not module name.

Mostly a mechanical change + whitespace fixes.
