Subject: Applied "regulator: s2mps11: Fix buck7 and buck8 wrong voltages" to the regulator tree

The patch

   regulator: s2mps11: Fix buck7 and buck8 wrong voltages

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.2

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: s2mps11: Fix buck7 and buck8 wrong voltages

On S2MPS11 device, the buck7 and buck8 regulator voltages start at 750
mV, not 600 mV.  Using wrong minimal value caused shifting of these
regulator values by 150 mV (e.g. buck7 usually configured to v1.35 V was
reported as 1.2 V).

On most of the boards these regulators are left in default state so this
was only affecting reported voltage.  However if any driver wanted to
change them, then effectively it would set voltage 150 mV higher than
intended.
