Subject: [PATCH 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 in real or if it is a 'simulated' disabling. By 'simulated'
I mean that the regulator-fw think it is disabled but the switch keeps
on in real.

Since the revert patch is on Marks regulator repo, my patches are based
on his repo too.

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

Regards,
Marco
