You could add this and the other dts files to
dtb-$(CONFIG_ARCH_MEDIATEK) so the Mediatek device trees are compile
during the build

This should also have a mediatek,mt8135-timer compatible. Just in case
there are incompatibilities in the timer you are not aware of now you'll
still have the possibility later to distinguish between the mt6577 timer
and the mt8135 timer in the driver.

The patches look very nice to me, I'm glad to hear you have
plans to upstream more.

Yes, I agree. I'll wait for Matthias to pick up your patches

The patches look fine to me, apart from the inconsistency in the
subject. I will fix this when I pick them.
I'm just wondering if I should wait until we get an ACK from the DTS maintainer.

It surely doesn't hurt to wait a bit more, but if it takes too
long, you can just apply the patches. For all I can tell, only
documented bindings are used, and it's more important to
review new or extended bindings.

We could add the following patch to this series so we actually see
something on the console during development of the other drivers.
I only know the UART base addresses of the mt8135, so I don't know
if MEDIATEK_ is an appropriate prefix. Maybe it should be changed to
MT8135_.

Yes it should be MT8135_ as other chips have the UART mapped to
different addresses [0].
