[PATCH 0/3] Add device tree support for kxcjk1013 accelerometer

[Robert Yang]

- Add a vendor prefix for Kionix Inc. to device tree bindings.
  There is already one other Kionix accelerometer (kxsd9) with device tree
  bindings but this vendor prefix hasn't been documented.
- Document the kxcjk1013 device tree bindings.
- Add device tree support for Kionix kxcjk1013 accelerometer sensors.

This looks like an ACPI binding rather than a device name.  So
I'd drop this last one.
