Merge tag 'regmap-v4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"This has been a very busy release for regmap, not just in cleaning up
the mess we got ourselves into with the endianness handling but also
in other areas too:
- Fixes for the endianness handling so that we now explicitly default
to little endian (the code used to do this by accident). This
fixes handling of explictly specified endianness on big endian
systems.
- Optimisation of the implementation of register striding.
- A refectoring of the _update_bits() code to reduce duplication.
- Fixes and enhancements for the interrupt implementation which make
it easier to use in a wider range of systems"
