Merge tag 'docs-4.9' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet:
 "This is the documentation update pull for the 4.9 merge window.

  The Sphinx transition is still creating a fair amount of work. Here we
  have a number of fixes and, importantly, a proper PDF output solution,
  thanks to Jani Nikula, Mauro Carvalho Chehab and Markus Heiser.

  I've started a couple of new books: a driver API book (based on the
  old device-drivers.tmpl) and a development tools book. Both are meant
  to show how we can integrate together our existing documentation into
  a more coherent and accessible whole. It involves moving some stuff
  around and formatting changes, but, I think, the results are worth it.
  The good news is that most of our existing Documentation/*.txt files
  are *almost* in RST format already; the amount of messing around
  required is minimal.

  And, of course, there's the usual set of updates, typo fixes, and
  more"

+Frame Buffer Library
+====================
+
+The frame buffer drivers depend heavily on four data structures. These
+structures are declared in include/linux/fb.h. They are fb_info,
+fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs. The last
+three can be made available to and from userland.
+
+fb_info defines the current state of a particular video card. Inside
+fb_info, there exists a fb_ops structure which is a collection of
+needed functions to make fbdev and fbcon work. fb_info is only visible
+to the kernel.
+
+fb_var_screeninfo is used to describe the features of a video card
+that are user defined. With fb_var_screeninfo, things such as depth
+and the resolution may be defined.
+
+The next structure is fb_fix_screeninfo. This defines the properties
+of a card that are created when a mode is set and can't be changed
+otherwise. A good example of this is the start of the frame buffer
+memory. This "locks" the address of the frame buffer memory, so that it
+cannot be changed or moved.
+
+The last structure is fb_monospecs. In the old API, there was little
+importance for fb_monospecs. This allowed for forbidden things such as
+setting a mode of 800x600 on a fix frequency monitor. With the new API,
+fb_monospecs prevents such things, and if used correctly, can prevent a
+monitor from being cooked. fb_monospecs will not be useful until
+kernels 2.5.x.
