Subject: Applied "regulator: 88pm800: Add 88pm860 regulator support" to the regulator tree
The patch
regulator: 88pm800: Add 88pm860 regulator support
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: 88pm800: Add 88pm860 regulator support
88PM860 falls under 88pm800 family of devices, with
additional feature enhancements, like,
- 88pm860 had additional BUCK regulator (BUCK6 and BUCK1B)
- Additional LDO (LDO20)
- different voltage and current capability
This patch adds 88PM860 related buck/ldo voltage/current data to
the driver, and creates the regulator_desc table.
With addition of new device to the driver, couple of unavoidable
changes,
- The table gets referenced using regulator ID (PM800_ID_xxx),
so table also needs to be created using ID.
- The naming convention of voltage tables would no longer be
mapped to respective ldos/bucks, so this patch also renames
to more generic name.
TODO:
- Validation on 88PM800 device, looking for some help here, as I do
not have any platform with 88PM800 device.
