of: clean-up unnecessary libfdt include paths

2015-06-05T01:16:47Z

With the libfdt include fixups to use "" instead of <> in the latest dtc import in commit 4760597 (scripts/dtc: Update to upstream version 9d3649bd3be245c9), it is no longer necessary to add explicit include paths to use libfdt. Remove these across the kernel.

dt: OF_UNITTEST make dependency broken

2015-03-25T05:43:44Z

If CONFIG_OF_UNITTEST=y then a kernel image make will always cause .version to be incremented, even if there are not source changes. This is caused by a lack of dependency tracking and checking for drivers/of/unittest-data/testcases.dtb.o. Signed-off-by: Frank Rowand Signed-off-by: Rob Herring

of/overlay: Introduce DT overlay support

2014-11-24T22:25:10Z

Overlays are a method to dynamically modify part of the kernel's device tree with dynamically loaded data. Add the core functionality to parse, apply and remove an overlay changeset. The core functionality takes care of managing the overlay data format and performing the add and remove. Drivers are expected to use the overlay functionality to support custom expansion busses commonly found on consumer development boards like the BeagleBone or Raspberry Pi. The overlay code uses CONFIG_OF_DYNAMIC changesets to perform the low level work of modifying the devicetree. Documentation about internal and APIs is provided in Documentation/devicetree/overlay-notes.txt v2: - Switch from __of_node_alloc() to __of_node_dup() - Documentation fixups - Remove 2-pass processing of properties - Remove separate ov_lock; just use the DT mutex. v1: - Drop delete capability using '-' prefix. The '-' prefixed names are valid properties and nodes and there is no need for it just yet. - Do not update special properties - name & phandle ones. - Change order of node attachment, so that the special property update works.

of/unittest: Rename selftest.c to unittest.c

2014-11-04T16:43:07Z

This is unit testing code. It should use that name because it makes more sense than 'selftest'. Rename the files to match and rename the config variable. Signed-off-by: Grant Likely

of: Introduce Device Tree resolve support.

2014-10-04T20:24:26Z

Introduce support for dynamic device tree resolution. Using it, it is possible to prepare a device tree that's been loaded on runtime to be modified and inserted at the kernel live tree. Export of of_resolve and bug fix of double free by Guenter Roeck Signed-off-by: Pantelis Antoniou [grant.likely: Don't need to select CONFIG_OF_DYNAMIC and CONFIG_OF_DEVICE] [grant.likely: Don't need to depend on OF or !SPARC] [grant.likely: Factor out duplicate code blocks into single function] Signed-off-by: Grant Likely

Adding selftest testdata dynamically into live tree

2014-07-25T06:18:13Z

This patch attaches selftest's device tree data (required by /drivers/of/selftest.c) dynamically into live device tree. First, it links selftest device tree data into the kernel image and then iterates over all the nodes and attaches them into the live tree. Once the testcases are complete, it removes the data attached. This patch will remove the manual process of addition and removal of selftest device tree data into the machine's dts file. Tested successfully with current selftest's testcases. Signed-off-by: Gaurav Minocha [glikely: Removed ability to build as a module and fixed no-devicetree bug] Signed-off-by: Grant Likely

of: Move CONFIG_OF_DYNAMIC code into a separate file

2014-07-07T12:59:45Z

Split the dynamic device tree code into a separate file to make it really clear what features CONFIF_OF_DYNAMIC add to the kernel. Without CONFIG_OF_DYNAMIC only properties can be changed, and notifiers do not get sent. Enabling it turns on reference counting, notifiers and the ability to add and remove nodes. v2: Moved of_node_release() into dynamic.c Signed-off-by: Grant Likely Signed-off-by: Pantelis Antoniou Cc: Rob Herring

of/fdt: add FDT address translation support

2014-05-20T20:19:25Z

Copy u-boot's FDT address translation code from common/fdt_support. This code was originally based on the kernel's unflattened DT address parsing code. This commit can be reverted once relicensing of this code to GPLv2/BSD is done and it is added to libfdt. Signed-off-by: Rob Herring Acked-by: Grant Likely

of/fdt: Convert FDT functions to use libfdt

2014-04-30T05:59:15Z

The kernel FDT functions predate libfdt and are much more limited in functionality. Also, the kernel functions and libfdt functions are not compatible with each other because they have different definitions of node offsets. To avoid this incompatibility and in preparation to add more FDT parsing functions which will need libfdt, let's first convert the existing code to use libfdt. The FDT unflattening, top-level FDT scanning, and property retrieval functions are converted to use libfdt. The scanning code should be re-worked to be more efficient and understandable by using libfdt to find nodes directly by path or compatible strings.
