I think he used my upstreaming branch where I store the patches I sent
and will send to the mailing list: [0].

I forgot there is a dependency between this patch and [1], and I forgot
to test this patch serie independenly from the other commits from my
branch. I will make sure to not forget next time.

So from this patch serie, only patch 1-2, 6-7 can be applied since they
don't have any hidden dependency:
  dt-bindings: usb: mediatek,mtu3: add binding for MT8195 SoC
  arm64: dts: mediatek: mt8195: add ssusb support
  arm64: dts: mediatek: mt8195-demo: Remove input-name property
  arm64: dts: mediatek: mt8195-demo: enable uart1
