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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJT6M7XAAoJEMWQL496c2LNTTgP/2rXyrTTGZpK/qrLKHWKYHvr XL7tcTkhA0OLU64E37fB+xtDXyBYnLsharuwUFSd1LlL1Wnc1cZN5ORRlMJbmjUR Wvwl0A8/mkhGl4tzzKgJ4z4rMJXvlZfJRpnVoRB5FOn90LI7k/jsf5rIwF/6S90B 6D6II0r4RG9ku1m7g70cToxcIFCzp0V+eu2tym9GnhsyGKlunPT9iNiTpwfVhPAj QUvMPKIQXReOv6xDU5q6E07839IMf7SdAvciBTHGnCDD7sGziHvnBIShj/2vTDAF 27sGRKrWUnnuxRUMOoIudiYyeHXIdt1WXp6FsS/ztVI37Ijh9YPShJwWGhQDppnp 4tcoSdefqw9IRUajAVWsB0RUW/tCL4a7tggWofylOA6itDi+HZnw6YafE1G1YzxF q8OFo9uqLcmFQfHDJpk+sdtXoMZzOgrxlEscsGsQ8kd2Uoe8+chgR9EY1sqPkWVF Zw0FJCTB6spBlsnXeboBGrnvpbPkacwhvesIFO0IANy4j4R55xlEeTcs1fe3ubUf UhNyyFdnCAUA7e5CAabcAQYsdbEKG6v0Il3H6xts36c8lXCSFXVgNcw5mdCpFCcQ DZ3/1FGSVzkYNXX8hlzIn1W0dqvwn4x0ZbnpXUJrGUBpSmjt9qkXx0XbdeFwartU 7X4tNGS1jfNYhOdP87jF =8IFz -----END PGP SIGNATURE----- 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.
