The patch

   regulator: arizona-ldo1: Move pdata into a separate structure

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: arizona-ldo1: Move pdata into a separate structure

In preparation for sharing this driver with Madera, move the pdata
for the LDO1 regulator out of struct arizona_pdata into a dedicated
pdata struct for this driver. As a result the code in
arizona_ldo1_of_get_pdata() can be made independent of struct arizona.

This patch also updates the definition of struct arizona_pdata and
the use of this pdata in mach-crag6410-module.c
