Subject: [PATCH v2 0/2] Re-Enable support to disable switch regulators

Hi,

Anson had added the support to disable the switched regulators, but
there were regressions [1] with old dtb's, so the commit was reverted [2].
At all, the support to disable the switch regulators seems to me to be a
good feature. But we have to add a special dt-property to avoid
regressions with older kernels. The property allows the user to decide if
the switch regulators should be disabled or not.

Since the revert patch is on Marks regulator repo, my patches are based
on his repo too. Each commit has a changelog, so I ommit it here. I
tested it on a custom board.

Used Kernel:
Repo:
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git
Branch:
regulator/for-4.19

Regards,
Marco
