Subject: Applied "regulator: axp20x: Remove voltage readout support for switch regulators" to the regulator tree

The patch

   regulator: axp20x: Remove voltage readout support for switch regulators

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: axp20x: Remove voltage readout support for switch
 regulators

Switch-type regulators, such as DC1SW on AXP22X, are a secondary output
from DCDC1. They are just an on/off switch, and the driver should not
try to read its voltage directly from the DCDC1 control registers.

Instead, the core will pass down the voltage from the regulator supply
chain.
