of: Add KUnit test to confirm DTB is loaded Add a KUnit test that confirms a DTB has been loaded, i.e. there is a root node, and that the of_have_populated_dt() API works properly. We skip the test when CONFIG_OF_EARLY_FLATREE=n because in that case we know architecture code hasn't called unflatten_(and_copy_)?device_tree() which would populate some sort of root node.

of: Create of_root if no dtb provided by firmware When enabling CONFIG_OF on a platform where 'of_root' is not populated by firmware, we end up without a root node. In order to apply overlays and create subnodes of the root node, we need one. Create this root node by unflattening an empty builtin dtb. If firmware provides a flattened device tree (FDT) then the FDT is unflattened via setup_arch(). Otherwise, the call to unflatten(_and_copy)?_device_tree() will create an empty root node. We make of_have_populated_dt() return true only if the DTB was loaded by firmware so that existing callers don't change behavior after this patch. The call in the of platform code is removed because it prevents overlays from creating platform devices when the empty root node is used.

of: Add OF_DMA_DEFAULT_COHERENT & select it on powerpc There's an OF helper called of_dma_is_coherent(), which checks if a device has a "dma-coherent" property to see if the device is coherent for DMA. But on some platforms devices are coherent by default, and on some platforms it's not possible to update existing device trees to add the "dma-coherent" property. So add a Kconfig symbol to allow arch code to tell of_dma_is_coherent() that devices are coherent by default, regardless of the presence of the property. Select that symbol on powerpc when NOT_COHERENT_CACHE is not set, ie. when the system has a coherent cache.

of: change overlay apply input data from unflattened to FDT Move duplicating and unflattening of an overlay flattened devicetree (FDT) into the overlay application code. To accomplish this, of_overlay_apply() is replaced by of_overlay_fdt_apply(). The copy of the FDT (aka "duplicate FDT") now belongs to devicetree code, which is thus responsible for freeing the duplicate FDT. The caller of of_overlay_fdt_apply() remains responsible for freeing the original FDT. The unflattened devicetree now belongs to devicetree code, which is thus responsible for freeing the unflattened devicetree. These ownership changes prevent early freeing of the duplicated FDT or the unflattened devicetree, which could result in use after free errors. of_overlay_fdt_apply() is a private function for the anticipated overlay loader. Update unittest.c to use of_overlay_fdt_apply() instead of of_overlay_apply(). Move overlay fragments from artificial locations in drivers/of/unittest-data/tests-overlay.dtsi into one devicetree source file per overlay. This led to changes in drivers/of/unitest-data/Makefile and drivers/of/unitest.c. - Add overlay directives to the overlay devicetree source files so that dtc will compile them as true overlays into one FDT data chunk per overlay. - Set CFLAGS for drivers/of/unittest-data/testcases.dts so that symbols will be generated for overlay resolution of overlays that are no longer artificially contained in testcases.dts - Unflatten and apply each unittest overlay FDT using of_overlay_fdt_apply(). - Enable the of_resolve_phandles() check for whether the unflattened overlay is detached. This check was previously disabled because the overlays from tests-overlay.dtsi were not unflattened into detached trees. - Other changes to unittest.c infrastructure to manage multiple test FDTs built into the kernel image (access by name instead of arbitrary number). - of_unittest_overlay_high_level(): previously unused code to add properties from the overlay_base devicetree to the live tree was triggered by the restructuring of tests-overlay.dtsi and thus testcases.dts. This exposed two bugs: (1) the need to dup a property before adding it, and (2) property 'name' is auto-generated in the unflatten code and thus will be a duplicate in the __symbols__ node - do not treat this duplicate as an error.

Making FIXED_PHY a bool option also cannot work, since it depends on PHYLIB, which again is tristate. This version now uses 'select FIXED_PHY' to ensure that the fixed-phy portion of of_mdio is not optional. The main downside of this is a small increase in code size for cases that do not need fixed phy support, but it should avoid all of the link-time problems.

of/overlay: Introduce DT overlay support 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.

This allows userland applications such as kexec to access the raw binary. The fact that this node does not reside under /sys/firmware/device-tree is deliberate: FDT is also used on arm64 UEFI/ACPI systems to communicate just the UEFI and ACPI entry points, but the FDT is never unflattened and used to configure the system. A CRC32 checksum is calculated over the entire FDT blob, and verified at late_initcall time. The sysfs entry is instantiated only if the checksum is valid, i.e., if the FDT blob has not been modified in the mean time. Otherwise, a warning is printed.

of: Fixing OF Selftest build error 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. Signed-off-by: Gaurav Minocha <gaurav.minocha.os@gmail.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>

Adding selftest testdata dynamically into live tree 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 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.

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

drivers: of: add initialization code for dma reserved memory This patch adds device tree support for contiguous and reserved memory regions defined in device tree. Large memory blocks can be reliably reserved only during early boot. This must happen before the whole memory management subsystem is initialized, because we need to ensure that the given contiguous blocks are not yet allocated by kernel. Also it must happen before kernel mappings for the whole low memory are created, to ensure that there will be no mappings (for reserved blocks) or mapping with special properties can be created (for CMA blocks). This all happens before device tree structures are unflattened, so we need to get reserved memory layout directly from fdt. Later, those reserved memory regions are assigned to devices on each device structure initialization.

pci/of: Match PCI devices to OF nodes dynamically powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

Begin to consolidate of_device.c This moves all the common parts for the Sparc, Sparc64 and PowerPC of_device.c files into drivers/of/device.c. Apart from the simple move, Sparc gains of_match_node() and a call to of_node_put in of_release_dev(). PowerPC gains better recovery if device_create_file() fails in of_device_register().
