This patch adds support for KXTJ2-1009 3-axis acceleromenter sensor.
KXTJ2-1009 uses the same register definitions as KXCJK-1013.
The specification for KXTJ2-1009 can be downloaded from:

This chip has a motion detect capability. Using IIO events to
specify thresholds and pushing events.
In addition a new trigger of type any-motion is added, which
pushes data to buffer only when there is any movement.

- Both motion detect and data ready can be enabled together
- Sending RISING/FALLING events based on int status
- Separate interrupt configuration for data ready and motion detect

In an effort to improve raw read performance and at the same time enter
low power state at every possible chance.
For raw reads, it will keep the system powered on for a default or user
specified time, via autosuspend_delay attribute of device power.
This will help read multiple samples without power on/off sequence.
For triggers it will keep the system on till, requested to be turned
off by trigger state by utilizing run time PM usage counters.
When runtime pm is not enabled, then it keeps the chip in operation
mode always.

driver uses i2c_smbus_read_word_data() to the data in the trigger handler and hence
already does endianness conversion; the I2C chip has data in little endian, but the
value is provides in CPU endianness

Assigning indio_dev->trig is not a good idea, as this can result in
wrong reference count for trigger device. If assigned, it is better to
increment reference counter by calling iio_trigger_get.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.

This chip needs explicit interrupt ack, introducing try_reenable
callback. Also removed separate function to ack interrupt as this
doesn't add any value.

Fix unlock at two places. One when i2c error occurs and other
when trigger set state when raw read is in progress.
