[PATCH 0/3] arm64: dts: mediatek: Add MT8186 Voltorb Chromebooks

[Chen-Yu Tsai]

Hi folks,

This series adds support for the MT8186 Voltorb Chromebooks. This is yet
another product based on the Corsola reference design. This particular
version features a higher end spec-ed SoC, necessitating a beefier
regulator for the big core cluster.

Patch 1 adds an entry for a new regulator IC. How this differs from
the previous iteration is not totally clear.

Patch 2 adds an entry for the Voltorb devices.

Patch 3 adds the device trees for the new devices.


Please have a look. I expect either all three patches to go through the
MediaTek tree; or the first can go through the regulator tree, and the
other two through the MediaTek tree.


Thanks
ChenYu

[PATCH 1/3] dt-bindings: regulator: mt6315: Document MT6319 PMIC

[Chen-Yu Tsai]

The MT6319 is a pin-compatible drop-in replacement for MT6315 with
slightly better electrical characteristics.

It's unclear whether there are any differences, since the downstream
implementation doesn't describe the MT6319 separately. Neither does the
implementation check chip IDs, even though those are available.

Add a new compatible for the MT6319 just in case differences are
discovered later and fall back to the MT6315 compatible.

This looks rather sane for a chromebook!

It really depends on the OEM/ODM for how many combinations they end up
producing...

[PATCH 3/3] arm64: dts: mediatek: Add MT8186 Voltorb Chromebooks

[Chen-Yu Tsai]

Add device trees for the MT8186 based Voltorb Chromebooks, also known
as the Acer Chromebook 311 (C723/C723T). The devices are clamshell
style laptops with an optional touchscreen.

The devices differ from the other existing MT8186 Chromebooks in that
it uses a higher speced / binned SoC which also requires a separate
PMIC for the big core cluster. Also, a different codec is used for
the internal speakers.

      commit: ffe4b381e2ea97c7a5868dbe841c7522b1b0b408

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
