[PATCH 0/3] pm8916: Add BMS and charger

[PATCH 0/3] pm8916: Add BMS and charger

[Nikita Travkin]

This series enables VM-BMS and LBC blocks in the pm8916 pmic.

The VM-BMS is a simple voltage monitoring block that allows the software
to estimate the battery capacity left.

The LBC is a linear battery charger for lipo batteries.

Add both devices to the pmic dtsi and enable them for Longcheer L8150
which makes use of them.

[PATCH 1/3] dt-bindings: mfd: qcom,spmi-pmic: Add pm8916 vm-bms and lbc

[Nikita Travkin]

PM8916 (and probably some other similar pmics) have hardware blocks for
battery monitoring and charging. Add patterns for respecive nodes so the
dt for those blocks can be validated properly.

Schemas for those devices were added in [1].

[PATCH 2/3] arm64: dts: qcom: pm8916: Add BMS and charger

[Nikita Travkin]

pm8916 contains some hardware blocks for battery powered devices:

- VM-BMS: Battery voltage monitoring block.
- LBC: Linear battery charger.

Add them to the pmic dtsi so the devices that make use of those blocks
can enable them.

[PATCH 3/3] arm64: dts: qcom: msm8916-longcheer-l8150: Add battery and charger

[Nikita Travkin]

Longcheer L8150 doesn't have any dedicated fuel-gauge or charger,
instead making use of the pmic hardware blocks for those purposes.

Add pm8916 bms and charger, as well as the battery cell description
that those devices rely on.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

The base for the series is generally the latest rc1. A different dependency

If you already ran 'make dt_binding_check' and didn't see the above

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

That's just ref, so no need for oneOf... unless you already think this
will grow with different schemas like the charger below?

Yes, I think some other PMICs have different battery/fuel-gauge
blocks too so I'd like to have some room for expansion here.

There is always room. Which other device will have different battery
charger?

I know of non-"VM" BMS block in PM8226. It's used on some Nokia
devices that people were working on so I expect it to appear in
the future.

There is also some BMS block in more modern PM6150 that I've
seen being looked at by people interested in bringing sm7125
phones upstream.

Both of those, to my knowledge, are completely different from
this VM-BMS block, which I believe was present in the generation
of pm8916, pm8909 and was abandoned again shortly after...
