Add bindings for the MediaTek mt8395-evk board.
The mt8359-evk board is also named as "Genio 1200-EVK".
MT8195 and MT8395 are the same family series SoC could share

How can be the same and have different numbers? You sill need dedicated
compatible.


The SoCs mt8195 and mt8395 are designed for different market application and physical characteristics, using different efuse values for distinction. The booting flow and configurations are controllered by the boot loaders, firmware, and TF-A. Therefore, the part numbers and procurement channels are different. The detail information of these efuse values is proprietary, so I cant disclose it futher. Hence the most of peripheral drivers and base address are almost the same.

1. Drivers? So we talk about compatibility, not the same.
2. "almost the same" is not the same. Follow the guidelines for writing
bindings.


Thanks for the review.

After internal confirmation and discussion, it can be confirmed that the MT8195 and MT8395 are identical SoCs from to binding's perspective. MediaTek hope the mt8395 boards could directly use mt8195.dtsi, without the need to create a separate mt8395.dtsi to include mt8195.dtsi. Therefore, we hope to fully adopt the bindings of mt8195. However, I will submit a revised patch for compatible since they are different boards.

If the reviewer still disagrees, then MediaTek will create a new binding and use mt8395.dtsi to include mt8195.dtsi to apply the separate bindings for differentiation.

Best regards,
Krzysztof
