The patch
regulator: fan53555: Add support for FAN53555UC13X type
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

IC type options 00, 13 and 23 are sharing the same DIE_ID 0. Let's differentiate between these revisions. FAN53555UC13X has the ID 0 and REV 0xf, starts at 800mV and increments in 10mV steps.
