The patch
regulator: qcom_smd: Fix voltage ranges for pma8084 ftsmps and pldo
has been applied to the regulator tree at
git://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: qcom_smd: Fix voltage ranges for pma8084 ftsmps
and pldo
The voltage ranges listed here are wrong. The pma8084 pldo
supports three different overlapping voltage ranges with
differing step sizes and the pma8084 ftsmps supports two. These
ranges can be seen in the "native" spmi regulator driver
(qcom_spmi-regulator.c) at pldo_ranges[] and ftsmps_ranges[]
respectively. Port these ranges over to the RPM SMD regulator
driver so that we list the appropriate set of supported voltages
on these types of regulators.
