[PATCH 00/14] arm64: dts: qcom: add refgen regulators where applicable

[Dmitry Baryshkov]

On several Qualcomm platforms the DSI internally is using the refgen
regulator. Document the regulator for the SDM670, Lemans and QCS8300
platforms. Add corresponding device nodes and link them as a supply to
the DSI node.

Are you sure the size is 0x84? Downstream and hwio_bitra_V1.cmm would
suggest size to be 0x60.

For sc7280, hwio_kodiak_E5.0.cmm does say 0x84 for refgen.

Apart from that, it's also what I have lying around somewhere, should've
upstreamed this already.

0x60

moreover, I see that there are two refgen regulators..

There are two refgens on each of the platforms, but I think the other
one is used in the automatic way. The HPG only tells us about
programming this one.

[01/14] regulator: dt-bindings: qcom,sdm845-refgen-regulator: document more platforms
        commit: e609438851928381e39b5393f17156955a84122a

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

It's likely that all PHY-ish hardware uses REFGEN, so please make
extra sure your patches won't kill DP/USB/camera

As far as I understand, DP and USB cast their votes directly in HW.
For camera... I don't know. Do we need an extra vote?
