+MediaTek MT6380 Regulator
+
+All voltage regulators provided by the MT6380 PMIC are described as the
+subnodes of the MT6380 regulators node. Each regulator is named according
+to its regulator type, buck-<name> and ldo-<name>. The definition for each
+of these nodes is defined using the standard binding for regulators at
+Documentation/devicetree/bindings/regulator/regulator.txt.
+
+The valid names for regulators are:

The patch
regulator: Add document for MediaTek MT6380 regulator
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

The MT6380 is a regulator found those boards with MediaTek MT7622 SoC
It is connected as a slave to the SoC using MediaTek PMIC wrapper which
is the common interface connecting with Mediatek made various PMICs.

The patch
regulator: mt6380: Add support for MT6380
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: mt6380: Add support for MT6380
The MT6380 is a regulator found those boards with MediaTek MT7622 SoC
It is connected as a slave to the SoC using MediaTek PMIC wrapper which
is the common interface connecting with Mediatek made various PMICs.

From: Sean Wang <sean.wang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
pwrap initialization is highly associated with the base SoC, so
update here for allowing pwrap_init without slave program which would be
used to those PMICs without extra encryption on bus such as MT6380.

From: Sean Wang <sean.wang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
Add MediaTek MT6380 regulator becoming one of PMIC wrapper slave
and also add extra new regmap_config of 32-bit mode for MT6380
since old regmap_config of 16-bit mode can't be fit into the need.
