This is wrong. Timer interrupts for both A53 and A57 are level triggered.

Please go and fix your firmware. Really...

Well, that's a total NAK. Neither of these properties are part of the
binding, and we've already established that none of that would never be
valid on arm64.

I suggest you finally do what we've been asking for years, which is to
fix your boot ROM by adding the 5 lines of assembly code that are needed
instead of repeatedly post the same bogus DT files.

Thanks,
