It seems appropriate to have both > signed-offs? Yes, but as I mentioned: 1) submitter goes last; 2) SoB lines and Author(s) should reflect actual state of the sources. If patch has 2 SoBs I'm expecting see different names of Authors in the source code. *Or* in some cases it's possible to explain in the commit message why you have former SoB and for what the credit that person(s) get. >>> +#include > > > This was a suggestion of Darren Hart in agreement with Thomas Gleixner. > see > http://mailman.alsa-project.org/pipermail/alsa-devel/2016-October/113936.html Hmm... Thanks for pointing to this I didn't aware about such details. But... I still insist that is not a platform data at all in both cases. For clock I would suggest include/linux/clk/ with x86_ prefix. For the rest I have no strong opinion except trying to avoid platform_data wording in the path as much as possible. As an example I could recall DMA engine subsystem where we have include/linux/platform_data/dma-*.h and include/linux/dma/*.h So, this sounds more to me as include/linux/x86/pmc_atom.h > Darren, did we get your proposal right? >> >> Is it indeed platform data?

(Yes, I know about clk-lpss.h >> which is old enough and was basically first try of clk stuff on x86) -- With Best Regards, Andy Shevchenko
