Merge tag 'regulator-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator into next/drivers

Browse Source 
The pxa regulator branch removes the bq24022 driver, while a lot of
other regulator drivers got added in the regulator tree. This
resolves the trivial conflicts by merging in the regulator patches
that are already merged into v3.4.

Conflicts:
	drivers/regulator/Kconfig
	drivers/regulator/Makefile
