I'll revert this to use "ext_gmac".

I see.

I'll revert this to use "xin32k".

can I assume clock named "xin32k" is always enabled?
no need to describe consumer explicitly?

sorry, I was just wrong. I'll remove clocks and clock-names from here.

no idea, I just follow schematic. if it's really unusable on mainline,
I'll disable(remove) spi2.

I was wrong here too. I'll remove clocks and clock-names from here.
and if it makes tsadc non-working, I'll remove tsadc too for now.
