Subject: Applied "regulator: max8973: Set VSEL regmap ops if DVS GPIO is not set" to the regulator tree

The patch

   regulator: max8973: Set VSEL regmap ops if DVS GPIO is not set

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: max8973: Set VSEL regmap ops if DVS GPIO is not
 set

Use regmap helpers for get_voltage_sel and set_voltage_sel ops
if the DVS GPIO is not set.

The DVS GPIO allows on the fly selection of the VSEL register
from two choices. However, if it is not set, the VSEL register
will stay fixed and we can use the regmap ops. This allows use
of the *hardware_vsel* regulator APIs.
