New driver:
1) tmp006 IR thermopile driver. This is an unusual temperature sensor
and was taken in to IIO with the knowledge and agreement of a hwmon
maintainer.
It measures remote temperature using infrared emissions.
I guess taking this may mean we have to fight off submissions of
devices much more suited to hwmon but such is life and we end up
doing this from time to time already.
2) twl6030 adc driver.
Cleanups:
1) More devm_* cleanups following on from the introduction of
devm_iio_device_alloc. Mostly an heroic effort from
Sachin Kamat!
2) Introduce devm_iio_trigger_alloc etc to handle trigger
allocation and deallocation in a managed fashion. There
aren't as many instances of triggers as devices, but this
will allow futher reduction in error patch complexity in
some of our most complex drivers making it a very good thing.
3) Trivial removal of unused defines in adjd_s311
4) Drop some write_raw_get_fmt callbacks where they were only
returning the default value.
5) Change mxs-lradc realbits to 12. Whilst an 18bit register
is used on the device, in its current mode only 12 bits of
useful data are returned. For now the packing is unchanged
in the buffer and this change mainly effects the input support
in the driver.

Implement clk-mux remuxing if the CLK_SET_RATE_NO_REPARENT flag isn't
set. This implements determine_rate for clk-mux to propagate to each
parent and to choose the best one (like clk-divider this chooses the
parent which provides the fastest rate <= the requested rate).
The determine_rate op is implemented as a core helper function so that
it can be easily used by more complex clocks which incorporate muxes.

Add core support to allow clock implementations to select the best
parent clock when rounding a rate, e.g. the one which can provide the
closest clock rate to that requested. This is by way of adding a new
clock op, determine_rate(), which is like round_rate() but has an extra
parameter to allow the clock implementation to optionally select a
different parent clock. The core then takes care of reparenting the
clock when setting the rate.
The parent change takes place with the help of some new private data
members. struct clk::new_parent specifies a clock's new parent (NULL
indicates no change), and struct clk::new_child specifies a clock's new
child (whose new_parent member points back to it). The purpose of these
are to allow correct walking of the future tree for notifications prior
to actually reparenting any clocks, specifically to skip child clocks
who are being reparented to another clock (they will be notified via the
new parent), and to include any new child clock. These pointers are set
by clk_calc_subtree(), and the new_child pointer gets cleared when a
child is actually reparented to avoid duplicate POST_RATE_CHANGE
notifications.
Each place where round_rate() is called, determine_rate() is checked
first and called in preference. This restructures a few of the call
sites to simplify the logic into if/else blocks.

In case compression fails, pstore will capture the uncompressed
