MediaTek ARM64 DTS updates for v6.10
This introduces the new Airoha (MediaTek) EN7581 home networking
platform (routers) in early stages, but with support for its
Evaluation Board, a few more MediaTek based machines, and
improvements for existing ones.
For the MT7981 router SoC we get pinctrl support, along with the
enablement of its watchdog and integrated WiFi controller, other
than the introduction of a new machine based on this chip: the
Cudy WR3000 V1 router.
Some advancements have been done also on the MT7988 SoC, which
gains support for its USB XHCI controllers.
MediaTek Genio SoCs also get attention, with the introduction of a
basic device tree for the MT8390 Genio 700-EVK board, and for the
MT8395 Genio 1200 powered Kontron 3.5"-SBC-i1200.
Additionally, the Genio 1200 Radxa NIO12L board gets support for
USB Role Switching and proper PCI-Express controller PM suspend
and resume, other than finally enabling CPU and GPU frequency
and voltage scaling for improved efficiency.
Speaking of MediaTek Kompanio SoCs (Chromebooks) instead, thanks
to community interest and help in testing, there comes support for
the MT8195-powered HP Chromebook X360 13b-ca0002sa;
Besides that, this also adds a few other cleanups and improvements
for all machines using the MT8183, MT8192, MT8195/MT8395 SoCs.
In particular:
- The MediaTek Smart Voltage Scaling (SVS) is now fully working
those SoCs, bringing further power efficiency improvements;
- Thermal zones were refactored on MT8183 for consistency with
the other MediaTek SoCs and for readability
- MT8186 and MT8188 get an initial node for the LVTS Thermal
Controller (SoC-internal temperatures)
- Sound DAI links are now consistently specified in device tree
on MT8195 and MT8186 machines
- Some cleanups for unused/legacy devicetree properties
