Merge tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux

Pull device tree updates from Grant Likely:
 "The branch contains the following device tree changes the v3.17 merge
  window:

  Group changes to the device tree.  In preparation for adding device
  tree overlay support, OF_DYNAMIC is reworked so that a set of device
  tree changes can be prepared and applied to the tree all at once.
  OF_RECONFIG notifiers see the most significant change here so that
  users always get a consistent view of the tree.  Notifiers generation
  is moved from before a change to after it, and notifiers for a group
  of changes are emitted after the entire block of changes have been
  applied

  Automatic console selection from DT.  Console drivers can now use
  of_console_check() to see if the device node is specified as a console
  device.  If so then it gets added as a preferred console.  UART
  devices get this support automatically when uart_add_one_port() is
  called.

  DT unit tests no longer depend on pre-loaded data in the device tree.
  Data is loaded dynamically at the start of unit tests, and then
  unloaded again when the tests have completed.

  Also contains a few bugfixes for reserved regions and early memory
  setup"
