[PATCH v2 1/2] dt-bindings: regulator: add pca9450: Add regulator-allowed-modes

[Martijn de Gouw]

Make the PWM mode on the buck controllers configurable from devicetree.
Some boards require forced PWM mode to keep the supply ripple within
acceptable limits under light load conditions.

[PATCH v2 2/2] regulator: pca9450: Add support for mode operations

Make the PWM mode on the buck controllers configurable from
devicetree. Some boards require forced PWM mode to keep the supply
ripple within acceptable limits under light load conditions.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

My bot found errors running 'make dt_binding_check' on your patch:

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

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.

      commit: 2616e5f4fe04eb25eb5cbabc0a3a2a374e14008e

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

Rob reported binding has failure (which also means binding was not
tested). Can you drop the patch?

That seemed to just be due to v1 splitting the header with the constants
from the binding change (the issue was that the header wasn't there)
which should be fixed by this version?

No, this v2:

https://lore.kernel.org/all/174801020316.1711348.10193654747801258488.robh@kernel.org/

I must admit after quick look I don't see the cause error, but
nevertheless this should be address by someone, preferably author.

Best regards,
