[PATCH v4 00/20] iio: ST clean-ups and new sensor support

[Lee Jones]

Hi Jonathan,

Hopefully I've covered all of your points in this new set.

This patch-set includes a few clean-ups surrounding error handling and
non-mandatory functionality along with regulator support and the addition
of a new pressure/temperature sensor (LPS001WP).

Everything has been tested with Device Tree.

v2:
 - Rebased onto Linux -next as requested by Jonathan
 - Reworked clean-up patch to address Jonathan's concerns
 - Added binding document (inc regulators)
 - Extended regulator support in the driver
 - Re-worked Data Ready pin handling

v3:
 - Standardise sensor names: <model>_<sensor-type>
 - Added error handling clean-ups
 - More binding documents; for magn, accel and gyro
 - Message on successful sensor bring-up; for press, magn, accel and gyro
 - More device enablement for ux500 by way of CONFIGs
 - New neat reorder/grouping of patches

v4:
 - Remove "registered" prints
 - Remove *_<dev_name> appends
 - Fix patch mangle
 - CC DT ML on bindings
 - Realisation that we're using a different Accel & Magn chip
 - Move (irq > 0) back into the error path
 - Squash CONFIG enablement into one patch
