Configure chip to data ready mode in selftest and count received
interrupts to see that interrupt line(s) are working.Signed-off-by: Samu Onkalo
Acked-by: Eric Piel
Signed-off-by: Guenter Roeck -
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 operations and
interrupts needed for one data update.Signed-off-by: Samu Onkalo

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.Signed-off-by: Samu Onkalo

Added default output data rate setting to platform data.
If default rate is 0, reset default value is used.
Added control for duration via platform data.
Added possibility to configure interrupts to trig on
both rising and falling edge. The lis3 WU unit can be
configured quite many ways and with some configurations it
is quite handy to get coordinate refresh when some
event trigs and when it reason goes away.Signed-off-by: Samu Onkalo

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.Signed-off-by: Samu Onkalo

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.Signed-off-by: Samu Onkalo

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 that
there was an interrupt.Signed-off-by: Samu Onkalo

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

According to the documentation, simply reading the respective MSR
isn't sufficient: It should be written with zeros, cpuid(1) be
executed, and then read (see arch/x86/kernel/cpu/intel.c for an

The axis-mapping of lis3dev device on many (rather most) HP machines
doesn't follow the standard. When each new model appears, users need to
adjust again. Testing this requires the rebuild of kernel, thus it's not
trivial for end-users.This patch adds a module parameter "axes" to allow a custom axis-mapping
without patching and recompiling the kernel driver. User can pass the
parameter such as axes=3,2,1. Also it can be changed via sysfs.Signed-off-by: Takashi Iwai

Signed-off-by: Linus Torvalds -
exofs_new_inode() was incrementing the inode->i_count and
decrementing it in create_done(), in a bad attempt to make sure
the inode will still be there when the asynchronous create_done()
finally arrives. This was very stupid because iput() was not called,
and if it was actually needed, it would leak the inode.However all this is not needed, because at exofs_evict_inode()
we already wait for create_done() by waiting for the
object_created event. Therefore remove the superfluous ref counting
and just Thicken the comment at exofs_evict_inode() a bit.While at it change places that open coded wait_obj_created()
to call the already available wrapper.CC: Dave Chinner
