    Pull DeviceTree updates from Rob Herring:
    "A bigger diffstat than usual with the kbuild changes and a tree wide
    fix in the binding documentation.

    Summary:

    - kbuild cleanups and improvements for dtbs

    - Code clean-up of overlay code and fixing for some long standing
    memory leak and race condition in applying overlays

    - Improvements to DT memory usage making sysfs/kobjects optional and
    skipping unflattening of disabled nodes. This is part of kernel
    tinification efforts.

    - Final piece of removing storing the full path for every DT node.
    The prerequisite conversion of printk's to use device_node format
    specifier happened in 4.14.

    - Sync with current upstream dtc. This brings additional checks to
    dtb compiling.

    - Binding doc tree wide removal of leading 0s from examples

    - RTC binding documentation adding missing devices and some
    consolidation of duplicated bindings

    - Vendor prefix documentation for nutsboard, Silicon Storage

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

    Having device_nodes be kobjects is only needed if sysfs or OF_DYNAMIC is
    enabled. Otherwise, having a kobject in struct device_node is
    unnecessary bloat in minimal kernel configurations.

    Likewise, bin_attribute is only needed in struct property when sysfs is
    enabled, so we can make it configurable too.

  • 7518b5890   of/overlay: Introduce DT overlay support ... Browse Code »

    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.

    Once the testcases are complete, it removes the data attached.

    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.

    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.

  • 98d9f30c8   pci/of: Match PCI devices to OF nodes dynamically ... Browse Code »

    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.

    Add support for parsing the device tree for PHY devices on an MDIO bus.
    Currently many of the PowerPC ethernet drivers are open coding a solution
    for reading data out of the device tree to find the correct PHY device.
    This patch implements a set of common routines to:

    a) let MDIO bus drivers register phy_devices described in the tree, and
    b) let MAC drivers find the correct phy_device via the tree.

    Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for
    the i2c API". If i2c-core is compiled as a module, the helper needs
    to be compiled as a module, as well. Rename i2c.c to of_i2c.c to
    avoid name space conflict.

    [paulus@samba.org: Changed dependency from OF to PPC_OF to avoid
    sparc{32,64} allmodconfig breakage.]
