The point here would be to know if you need to enable a special timer
from the mtk-timer block to get the arch timer working.
In any case, you will need some sort of timer. This dts does not
describe the mtk-timer (may in the mt8173 it does not exist) but
defines the clocks clk26m and clk32k. So if you don't use the
mtk-timer, please remove the clocks as there isn't a block using them.
Thanks,
