Document and add regulator support for the Nexperia NEX10000UB dual
output LCD bias power supply which provides programmable positive
and negative output voltages mainly for display panels applications.

The driver supports setting the output voltage from 4V to 6V in
100mV steps for each output via the I2C programming interface and
supports the enable GPIOs for both outputs.

Product datashet can be found online at [1].

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
