This series introduces Devicetrees for the MT8192-based Asurada platform
as well as Asurada Spherion and Asurada Hayato boards.
Support for the boards is added to the extent that is currently enabled
in the mt8192.dtsi, as to not add any dependencies to this series.
After the series adding various missing nodes on MT8192 [1] is merged, a
new series will be sent enabling the remaining devices on the Asurada
platform.
While the dts files added in this series introduce a couple new
dtbs_check warnings, they are fixed by another series [2].
This series was peer-reviewed internally before submission.

Introduce the MT8192 Asurada Chromebook platform, including the Asurada
Spherion and Asurada Hayato boards.
This is enough configuration to get serial output working on Spherion
and Hayato.

The Asurada platform has five I2C controllers and two SPI controllers
that are used. In preparation for enabling the devices connected to
these controllers, enable and configure their busses.

Add support for the ChromeOS Embedded Controller present on the Asurada
platform. It is connected through the SPI1 bus and offers several
functionalities: base detection, PWM controller, I2C tunneling,
regulators, Type-C connector management, keyboard and Smart Battery
Metrics (SBS).

Chromebooks' embedded keyboards differ from standard layouts for the
top row in that they have shortcuts in place of the standard function
keys. Map these keys to achieve the functionality that is pictured on
the printouts.

All machines of the Asurada platform have a touchscreen at address 0x10
in the I2C0 bus, but the devices vary: Spherion has the Elan eKTH3500
touchscreen, while Hayato has a generic HID-over-i2c touchscreen.
Add common support for the touchscreens on the platform and the
specifics in each board file.

The Spherion board has keyboard backlight controlled by the PWM signal
generated by the ChromeOS EC.
Enable PWM output for ChromeOS EC and add a PWM controlled LED node for
the keyboard backlight.

I'm honestly a bit confused about function of this.
Does this change the reported key codes via evdev interface?
Or is this just a hint to userspace? If yes, would libinput report
key presses as F-keys or the custom function keys?
Would users be able to use the usual key combination to switch
between TTYs?
Would programs requiring F-keys still work?
Best regards,

Not with this keyboard, since the embedded keyboard on Chromebooks doesn't have
F-keys.
This patch is just setting the keymap present on this platform, so that the
devicetree correctly describes the hardware.

This series was not only peer-reviewed internally, but also tested so, for the
entire series, other than my R-b, if that's relevant:

I think this should be "Google Hayato ...", and the one in spherion should
read "Google Spherion" as well?
These are project code names used in Google. Both devices use the common
"Asurada" hardware design, also done by Google.
> + compatible = "google,hayato-rev1", "google,hayato", "mediatek,mt8192";
You should add a patch adding this to the DT binding doc
Documentation/devicetree/bindings/arm/mediatek.yaml
Same for Spherion.
