1. Add compatible for MT8395.
2. Add bindings for the MediaTek mt8395-evk board, also known
as the "Genio 1200-EVK".
The MT8195 and MT8395 belong to the same SoC family,
with only minor differences in their physical characteristics.
They utilize unique efuse values for differentiation.
The booting process and configurations are managed by boot
loaders, firmware, and TF-A. Consequently, the part numbers
and procurement channels vary.

Do not attach (thread) your patchsets to some other threads (unrelated
or older versions). This buries them deep in the mailbox and might
interfere with applying entire sets.
Changes for v2:
- add more detail description for mt8395.
- add bindings for mt8395, and mt8395-evk.

I don't understand. You said last time this is fully compatible with
mt8195, so why it's not here?
Yes, mt8395 is fully compatible with mt8195.
But after reading Angelo's comment, we thought it is necessary to create a new
compatible to avoid confusion for users.

Although they are fully compatible, developers cannot arbitrarily replace the chip
on the board with another one. So separated bindings might be better.
Sorry you've misunderstood; I was trying to explain to Krzysztof that the two
SoCs are fully compatible... my suggestion was in like with what you're trying to
do as in I am agreeing with your first version, Macpaul, to inherit MT8195.
So,
- enum
- mediatek,mt8395-evk
- const: mediatek,mt8195
- const: mediatek,mt8395
Best regards,
Krzysztof
