Irqcfg moved to chip data instead of platform data.
This simplifies access in interrupt handler little bit.
Input device open and close functions set status for
interrupt threaded handler once.
Unnecessary check for interrupt source removed since
it is enough that active interrupt line indicates
Based on pm_runtime control, turn lis3 regulators on and off.
Perform context save and restore on transitions.
Feature is optional and must be enabled in platform data.

Call input device poll function at device open to refresh coordinates
immediately. This is needed for the case where poll interval is set to
zero and coordinate updates happens purely under interrupt control.

Sometimes lis3 chip seems to fail to setup factory tuning at boot up.
This probably happens if there is some odd power ramp down ramp up sequence
for example in device restart. Set boot bit in control2 register to
trig boot sequence manually and wait until it is finished.

If lis3lv02d_init_device fails, HW resources were not released
properly. In case of failure call release_resources if available.

Default fuziness is set smaller for 8 device.
In 12 bit device LSB is quite close to 1 mg
(mg = 1 / 1000 of earth gravity).
In 8bit device LSB is about 18 mg.
Set fuziness to 1 for 8 bit device.

Add optional blockread function to interface driver. If available
the chip driver uses it for data register access. For 12 bit device
it reads 6 bytes to get 3*16bit data. For 8 bit device it reads out
5 bytes since every second byte is dummy.
This optimizes bus usage and reduces number of
Configure chip to data ready mode in selftest and count received
interrupts to see that interrupt line(s) are working.

Add pm_runtime support to lis3 core driver.
Add pm_runtime support to lis3 i2c driver.
spi and hp_accel drivers are not yet supported. Old always
on functionality remains for those.
For sysfs there is 5 second delay before turning off the
chip to avoid long ramp up delay.

Changes are tested only with I2C interface using 8bit sensor since I don't
have other possibilities. Some features are not enabled
by default since I can't test them with all possible configurations.
Platform data contains field which controls new features.
Description about the changes:
0001:
I think this now addresses all the points raised in previous review, as well
as adding runtime power management support which is needed for MID
platforms.
From: Wen Wang wen.w.w...@intel.com
Initial release of the driver. Updated and verified on hardware.
Cleaned up as follows

It might work out right, but looks a bit random currently.
