This series extends the existing S2MPG10 PMIC driver to add support for
the regulators, and adds new S2MPG11 core and regulator drivers.
--- dependency note ---
This series must be applied in-order, due to the regulator drivers
depending on headers & definitions added by the bindings and core
drivers.
Due to patch context, there are dependencies on previous Samsung MFD
patches, hence this series is against current for-mfd-next.
While these patches compile, regulator probe will only be successful
with my deferrable regulators patches from
https://lore.kernel.org/r/20251227-regulators-defer-v1-0-3104b22d84cb@linaro.org
(already in linux-next).
I think patches up to and including mfd changes could go via the MFD
tree, and regulator patches using an immutable branch via the regulator
tree on top.
--- end ---
The patches are kept together in one series, due to S2MPG11 and its
regulators being very similar to S2MPG10.
The Samsung S2MPG11 PMIC is a Power Management IC for mobile
applications with buck converters, various LDOs, power meters, and
additional GPIO interfaces. It typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC and both are used on the
Google Pixel 6 and 6 Pro (oriole / raven).
A DT update for Oriole / Raven to enable these is required which I will
send out separately.
Cheers,
