This one still has a fair amount of code hiding in the .txt files, but
that's a separate job.

This one might be better called a "tool" rather than a "sample" - assuming
it actually still works, of course.  It hasn't seen a real update in the
Git era, which is a bit disconcerting.  Is it possible that this is dead
code that we might want to just get rid of?

If it stays, Documentation/laptops/laptop-mode.txt needs an update.

Documentation/auxdisplay/cfag12864b needs to be updated to reflect the new
home for the program (which probably does belong in samples/).

I wonder if these programs need MAINTAINERS entries too?

So I like the basic idea of these patches; it's the direction we've been
trying to push things for a little bit.  I have a couple of specific
comments for this one that may well apply to the others as well.

1) Is samples the right destination for these utilities?  Some of them
   might well be better placed under tools/ instead.  I'm not sure we've
   ever formally stated the purpose of those two subtrees; I see samples/
   as demonstrations of how to use something, while tools/ are utilities
   you might actually want to use for some purpose.  Something like
   getdelays might well fall into the latter group.  But maybe others
   disagree?

2) Tools like getdelays are referenced in the documents that have been
   left behind; see accounting/delay-accounting.txt, for example.  Those
   documents should be updated so that readers know where to find the
   referenced programs, wherever they end up.  Converting them to Sphinx
   while you're at it is an extra-credit exercise :)

Thanks,

jon

[PATCH 0/8] Move runnable examples code from Documentation to samples

2016-09-19 Thread Shuah Khan 
Move runnable examples code from Documentation to samples. I moved
just the example code, and left documentation files as is.

blackfin gptimers example code needs a bit of special handling since
it is a module. I will address it in a separate patch. 00-Index files
need to be updated due to this move which will be done another patch.

Shuah Khan (8):
  samples: move accounting example code from Documentation
  samples: move auxdisplay example code from Documentation
  samples: move laptops example code from Documentation
  samples: move mic/mpssd example code from Documentation
  samples: move misc-devices/mei example code from Documentation
  samples: move pcmcia example code from Documentation
  samples: move timers example code from Documentation
  samples: move watchdog example code from Documentation

[PATCH 3/8] samples: move laptops example code from Documentation

2016-09-19 Thread Shuah Khan 
Move laptops examples to samples and remove it from Documentation
Makefile. Create a new Makefile to build laptops. It can be built
from top level directory or from laptops directory:

Run make -C samples/laptops or cd samples/laptops; make
