The i2c0 node already inherits status = "okay" from mt8183-kukui-kakadu.dtsi,
this is redundant.

You can definitely avoid those ugly /delete-node/ statements: if you check more
closely, mt8183-kukui-kakadu.dtsi is used by only two *.dts files.

I would propose to move the touchscreen@10 node from kakadu.dtsi to kakadu.dts
and kakadu-sku22.dts: in my opinion, that will make things more readable, as
every board defines its own touchscreen.

It would be a different story if we had to duplicate that @10 node for something
like five times or more, but that's not the case.

This....

...should be done in one line, like so:

		interrupts-extended = <&pio 155 IRQ_TYPE_LEVEL_LOW>;

Actually, same comment goes for the panel node: kakadu.dtsi defines a panel
compatible "boe,tv105wum-nw0" but then you're overriding it here with the
starry panel.

You could leave the status = "okay" in kakadu.dtsi and move the panel compatible
to each *.dts board file, therefore increasing readability.

Same comment applies to sku38, of course.
