The SY7636A has some pins which can be hardwired or used to have more
more advanced power management available. As several devices containing
this regulator have these pins not hardwired, but instead connected to some
GPIO, enhance the driver to have them defined and initialized.
Also add the ability to power off the chip completely by defining some
input power supply.

Actually implementing better power management is planned to be
implemented as a second step. The regulators in the SY7636A should only
be on for a short time during display refresh, but currently they are
unconditionally forcefully enabled by the hwmon part of this chip.

Thanks!

[2/3] regulator: sy7636a: add gpios and input regulator
      commit: fb25114cd760c13cf177d9ac37837fafcc9657b5

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
