Damn, you're right... Sorry about that...

You need to pull the tag sunxi-clk-for-4.4 that has been merged in the
clk tree in 38ce30e29dc.

Mike, Stephen, will that tag be stable?

Arnd, do you want me to merge it in my DT branch, or do you want to
merge it yourself?

Thanks, and sorry again,
Maxime

I don't see that tag in your tree, Maxime? I also don't see 38ce30e29dc in
the clk tree on kernel.org.

I'm a little confused right now...

The tag is "sunxi-clocks-for-4.4":
    https://git.kernel.org/cgit/linux/kernel/git/mripard/linux.git/tag/?h=sunxi-clocks-for-4.4

The merge commit in the clk tree is 938ce30e29dc:
    https://git.kernel.org/cgit/linux/kernel/git/clk/linux.git/commit/?h=clk-next&id=938ce30e29dc

Thanks, so both the tag and the hash were missing a few characters. :-)

I've merged this in now. Note that this has resulted in a tree that won't
misect cleanly, since having the clk contents merged instead of used as a base
for the dt branch means that you could end up in a bisect state that has the DT
branch but not the clk branch.

These are some of the reasons why I'm not overly excited about these header
file dependencies. :(

Even if it has been merged before the DT patches have been applied?
That's not really what I'd expect from bisect :/

Yeah, I see why now. Your suggestion of using the raw values first and
then switch to using the headers make sense I guess, we'll try to
stick to that in the future.

Thanks!

Yeah, due to the way bisect works, the only way to guarantee
bisectability is if you base the DT branch on top of the clk branch
when you build it. Otherwise the bisect can come down the path of only
having the DT contents not the clk contents.

See how it works for you. If it's awkward to do that we can try
something else. I'd love to see some of these dependencies go away
though.

Why can't the dts changes be applied directly on top of the
branch that's in the clk tree and then sent off to arm-soc? The
git merge && git commit technique also works, but it introduces
an unnecessary merge commit into the history.

"base the DT branch on top of the clk branch" is exactly that, isn't it?

Yes. I mostly wanted to point out that you don't need to do the
git merge part when building that branch.

Wouldn't that mean that you have to rebase your whole DT branch
whenever a single patch introduces a dependency on some clock patch?

That depends on whether or not the single patch depends on the
other patches in the "DT" branch. If it did, then do the merge
and apply the single patch on top. But if doesn't, maybe it's
something like new SoC support that needs a binding header, I
would make a second DT branch that points at the branch in the
clk tree and then apply the dt patch directly on top.

Of course, this is just one way to do it. I'm mostly trying to
avoid unnecessary merges, but sometimes merges are unavoidable.
The most important thing is to maintain bisectability and to make
it clear why merges from other trees are done by putting some
sort of reason in the commit text of the merge.

I'm starting to find these header files somewhat tedious to deal with,
and I wish we could do it better. We're creating a lot of cross-tree
dependencies with these, usually jsut for one or two added lines in one
of these headers.

For those cases, I wonder if we should just take the DT change without using
the symbol for the first release, and then next release a cleanup patch that
moves over to include the header file and use that flag from there.

But I'm all ears looking for better suggestions too. I wish to move away from
the current model where we usually have to merge in a clk or pinctrl branch to
get this though.
