This series enables more functionality on the MT8195 Tomato Chromebooks,
bringing it to an almost usable state.

With this series, the device is able to boot from the MicroSD card
and is able to communicate with the EC for various functions,
including the enablement of the Chromebook's keyboard, battery
charging, fuel gauge and other standard ChromeOS EC functionality.

This also enables the Audio DSP, codec and sound card and adds support
for the regulators found on the SPMI bus.

What's missing (coming in the next part)?

* Format:    feature  (location)
*
* MediaTek vcodec enc/dec (mt8195.dtsi only)
* PCI-Express WiFi card (mt8195 and mt8195-cherry)
* VDOSYS1 (mt8195.dtsi and mediatek-drm/mmsys drivers)
* DP/eDP outputs for external/internal display (mt8195 and mt8195-cherry)
* LVTS Thermal Sensors (mt8195.dtsi, driver is missing)
* GPU support (comes later, clocks implementation is in the works)


### NOTE: ###

This series depends on MediaTek's MT8195 new device nodes [1] series
