    I'd add the MSTP7 clock node itself in the same patch...

OK. I tried to look at previous commits to figure out what goes in what patch.

    There's no single approach here... but it was just that your patch subject 
doesn't seem to correspond well to what the patch does.

But as Sergei mentioned, the addition of mstp7_clks to the .dtsi really belongs
in this patch.

Re: [PATCH v2 1/3] ARM: dts: r7s72100: add ethernet clock to device tree

[Simon Horman]

Thanks Chris,

I have queued up this and the following 2 patches for v4.9 (nothing more
for you to do unless something goes wrong in which case I'll let you know).

For future submissions please consider:
1. Supplying a cover letter (git format-patch has a --cover-letter option)
   for patch-sets comprising more than one patch. This allows you to describe
   an overview of what the series as a whole achieves. And is also
   convenient for maintainers to reply to when accepting your patches.
2. Starting a new thread for each new version of a patch/patch-set.

Different maintainers have different preferences. The above are mine.

OK. I can do that.

Does that mean to NOT use --in-reply-to= when submitting a v2,v3,etc... ????



One more question:
Can I submit a patches series now that just adds all the MSTP clock nodes that I'll be working on for the next couple weeks? (USB, SDHI, MMC)
Or, do I have to wait till I have the drivers working?
Or, better yet, can I add all the MSTP clocks that will probably get used at some point (basically, everything that we're using today in our 3.14 BSP).

Chris

I think so.

I think that would be ok. I would slightly prefer that MSTP patches are
added in such a way that they can be tested. But in this case I'm not
sure anyone would test them :^)
