[PATCH v1 0/7] mfd: sec: add support for s2mps16 pmic

[Ivaylo Ivanov]

Hey folks,

This patchset adds support for the s2mps16 pmic, used on devices like
the Samsung Galaxy S7, S7 edge and the Note 7. It is still wired over
I2C, unlike newer exynoses, but also can be communicated with via APM,
support for which is not done (and probably will never be, as it's
pretty much useless).

The order of patches is important, hence why I've not split it into
subsystems. Patch 1/7 should go before patch 2/7, as 2/7 includes the
file made at 1/7. The rest can be applied without a specific order.
Thanks!

Best regards,
Ivaylo

[PATCH v1 1/7] regulator: dt-bindings: add documentation for s2mps16-pmic regulators

[Ivaylo Ivanov]

The S2MPS16 is a PMIC found in exynos8890 devices, which controls voltage
regulators - 38 LDOs, of which 11 are used for CP, and 11 BUCKs, of which
1 is used for CP. Provide documentation for devicetree definitions,
regulator naming patterns, etc.

[PATCH v1 2/7] dt-bindings: mfd: samsung,s2mps11: add compatible for s2mps16-pmic

[Ivaylo Ivanov]

S2MPS16 is a PMIC present in Samsung's exynos8890 devices. It houses
voltage regulators (38 LDOs and 11 BUCKs), an RTC and a clocks module.
Add the compatible string "samsung,s2mps16-pmic" to the PMIC.

[PATCH v1 5/7] clk: s2mps11: add the support for S2MPS16 PMIC clock

[Ivaylo Ivanov]

Add the support for S2MPS16 PMIC clock, which is functionally the same
as the currently supported ones, with the exception of a different
register.

[PATCH v1 6/7] rtc: s5m: add support for S2MPS16 RTC

[Ivaylo Ivanov]

Add support for Samsung's S2MPS16 PMIC RTC, which has pretty much
identical functionality to the existing S2MPS15 support, with the
difference being the ST2 register.

[PATCH v1 7/7] regulator: s2mps11: add support for S2MPS16 regulators

[Ivaylo Ivanov]

S2MPS16 is a PMIC, manufactured by Samsung, particularly used in
exynos8890 based devices, featuring 38 LDOs, of which 11 are used for
CP, and 11 BUCKs, of which 1 is used for CP. Add driver support for
controlling all BUCKs and LDOs, except the ones used for CP, as they are
not documented enough and the vendor kernel doesn't handle them anyways.

The operation should not be present if it's not supported, and should
error out if mistakenly called on an invalid regulator.

Looks okay.  Once you have the Regulator Ack we can merge this through MFD.

This depends on mfd patch. Many maintainers would appreciate if you
mention it also in the patch changelog (---), not only cover letter.

Does the license 2.0+ (so 3.0 and so one) come from the downstream you
