Some additions to the manual page.

Similar comments to D55907. The structure looks good, but I did not review the clock method logic.

Looks like the logic covers all imaginable cases. Of course as result it is a bit complex. But if properly documented should be fine.

This looks straightforward to me. I did not review the recalc / set_freq methods in detail.

Skip the again test

Can you use the existing clk_fixed class for these clocks? It seems like it. See sys/dev/clk/clk_fixed.h.

This appears to be a duplicate of D55907. Is there a difference?

Thanks a lot for working on that! I miss the feature a lot.

Sorry if a dumb question. Trying to understand the Makefile logic. The statement

${PACKAGE}SCRIPTS+=     demo.setup \
                        demo.atfsh_like_setup

does it apply to all tests in the Makefile or there is some magic that makes the first word before the dot to limit application only to a test that is named as this word? Where does this logic live?

fix

Causes a panic. Abandoning.

I think we should probably have tests check we do the correct things when we get a jumbogram. If these tests aren't run they don't really help with that.

LGTM. Feel free to commit.
