We can do that, but I would prefer to see the clock driver early. So
that the DTS we carry around as complete as possible.

Yes, this is an evaluation platform which is an internal demo phone.
No difference to EVB. Would you suggest I change the name? If so, I will
change it to mt6755-evb.dtb. So will the compatible string in it.

OK, I will merge the clk later. However, the clk driver would be

The uart won't work without any clock node. It is OK like this. I just
wanted to emphasis that we should try to get the clock driver accpeted
early in the effort.

Got it. I will not include the clk dts & driver in basic chip patch
v2.We will submmit clk driver soon after this basic chip support patch.
