This patch adds suspend/resume support so that it is possible to
configure the LDOs and BUCKs as on or off during suspend phase as
well as to configure suspend specific voltages.

Hello Jagan,
as your new role as Maintainer of this driver, is there a chance to get
your Feedback/Ack/Review/Signed anytime soon?
Thanks

Please don't send new patches in reply to old threads, it buries things
and makes it much harder to follow what's going on. Start a new thread
for new submissions.

Thanks!
[1/1] regulator: pf8x00: Add suspend support
commit: 7fefe72b0f8c0d7e63af9810c4dcc88757eddcd5
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

[1/1] regulator: pf8x00: Add suspend support
commit: 7fefe72b0f8c0d7e63af9810c4dcc88757eddcd5
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
