of: Fixing OF Selftest build error

2014-08-03T18:21:28+00:00

This patch is to fix following error while compiling OF selftests.
"drivers/of/selftest.c:617:2: error: implicit declaration of function
'of_fdt_unflatten_tree'"

Now, CONFIG_OF_SELFTEST depends on CONFIG_OF_EARLY_FLATTREE so that the
broken configuration cannot be selected. Ultimately it would be a good
idea to allow CONFIG_OF_SELFTEST to select CONFIG_OF_EARLY_FLATTREE, but
there is a dependency problem on i386 and x86_64 that causes dtc to not
get built and causes the build to fail. That problem needs to be fixed
first.

Adding selftest testdata dynamically into live tree

2014-07-25T06:18:13+00:00

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.

of/fdt: Convert FDT functions to use libfdt

2014-04-30T05:59:15+00:00

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.

Merge branch 'devicetree/next-reserved-mem' into devicetree/next

of: remove /proc/device-tree

2014-03-11T20:48:32+00:00

The same data is now available in sysfs, so we can remove the code
that exports it in /proc and replace it with a symlink to the sysfs
version.

Tested on versatile qemu model and mpc5200 eval board. More testing
would be appreciated.

drivers: of: add initialization code for dynamic reserved memory

2014-03-11T17:26:58+00:00

This patch adds support for dynamically allocated reserved memory regions
declared in device tree. Such regions are defined by 'size', 'alignment'
and 'alloc-ranges' properties.

Based on previous code provided by Josh Cartwright

of: Allows to use the PCI translator without the PCI core

2014-02-20T15:34:35+00:00

Translating an address from a PCI node of the device-tree into a CPU
physical address doesn't require the core PCI support. Those
translations are just related to the device tree itself.

The use case to translate an address from a PCI node without actually
using the PCI core support is when one needs to access the PCI
controller without accessing any PCI devices.

Marvell SoCs, such as Kirkwood, Dove or Armada XP for instance, come
with an IP of a PCI controller. In the registers of this controller
are stored the ID and the revision of a SoC. With this patch it will
be possible to read the SoC ID of a board without any PCI device and
then without the PCI core support.

Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"
