From: Fabien Parent <[email protected]>
This adds minimal support for the Mediatek 8365 SOC and the EVK reference
board, allowing the board to boot to initramfs with serial port I/O.
Signed-off-by: Fabien Parent <[email protected]>
[[email protected]: Removed parts depending on drivers that aren't upstream yet, cleanups, add CPU cache layout, add systimer, fix GIC]

Unfortunately we are missing this compatible in the binding description.

Why don't we use a compatible like
"mediatek,mt8365-systimer", "mediatek,mt6795-systimer";
We would need to add this to the binding description as well.
I leave it up to you, but I'd advise to start with a minimal working DT which
includes only the bindings that are already merged. Then we can take the new
devices like mtu3, xhci, spidev or i2c later once they are ready.

True, overlooked that one.

This is actually added by an earlier patch within this series (5/7),
but since it isn't used anywhere yet, might as well drop it for now,
"mediatek,mtu3" by itself works.

Also added by an earlier patch within the series (6/7), and also not
used anywhere yet.

That was in an earlier revision and removed (because the binding
description wasn't merged yet). Can add it of course (but then
mediatek,mt8365-uart and friends should probably stay as well).
I'll post a new revision adding it back (along with the binding
description) and add the binding description for mt8365-uart as well
(getting it to the same place mediatek,mt8365-mtu3 and
mediatek,mt8365-xhci are now).
Let me know if you'd prefer a variant that drops mediatek,mt8365-uart,
mediatek,mt8365-mtu3, mediatek,mt8365-xhci and doesn't bring back
mediatek,mt8365-systimer -- either one works for me, the fallbacks are
sufficient to make it work.
