Subject: Applied "regulator: Revert "regulator: pfuze100: add enable/disable for switch"" to the regulator tree

The patch

   regulator: Revert "regulator: pfuze100: add enable/disable for switch"

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] regulator: Revert "regulator: pfuze100: add enable/disable
 for switch"

This reverts commit 5fe156f1cab4f340ddb6283c993912be77594016.

Commit 5fe156f1cab4 ("regulator: pfuze100: add enable/disable for switch")
causes boot regression on some platforms such as imx6sl-evk and
imx6sll-evk.

After this commit the SW4 regulator will be turned
off and since it supplies the DDR voltage on these boards, a
kernel hang is observed.

Revert it to avoid breaking old dtb's.
