This attribute allows to configure the update interval of ina226. Although
the bus and shunt voltage conversion times remain hardcoded to 1.1 ms, we can
now modify said interval by changing the averaging rate.
While we're at it - add an additional variable to ina2xx_data, which holds
the current configuration settings - this way we'll be able to restore the
configuration in case of an unexpected chip reset.

The shunt resistance can only be set via platform_data or device tree. This
isn't suitable for devices in which the shunt resistance can change/isn't
known at boot-time.
Add a sysfs attribute that allows to read and set the shunt resistance.

Shunt resistance values greater than the chip's calibration factor make no
sense since the actual value written to the register equals:
<calibration factor> / <shunt>
Bail-out from ina2xx_probe() if the configured value is greater than the
calibration factor.

Chips from the ina family don't like to be uninitialized. In case the power
is cut-off and restored again the calibration register will be reset
to 0 and both the power and current registers will remain at 0.
Check the calibration register in ina2xx_update_device() and reinitialize
the chip if needed.

it's not only badly racy, it's actually dead code - the call in

What we want is to have non-counting references to children in
pagecache of parent directory, and avoid picking them after a child
has been freed. Fine, so let's just have ->d_prune() clear
parent's inode "has directory contents in page cache" flag.
That way we don't need ->d_fsdata for storing offsets, so we can
use it as a quick and dirty "is it referenced from page cache"
flag.

A week's worth of fixes for various ARM platforms. Diff wise, the
largest fix is for OMAP to deal with how GIC now registers interrupts
(irq_domain_add_legacy() -> irq_domain_add_linear() changes).
Besides this, a few more renesas platforms needed the GIC instatiation
done for legacy boards. There's also a fix that disables coherency of
mvebu due to issues, and a few other smaller fixes.
