  • 15c9a0acc   of: create of_phandle_args to simplify return of phandle parsing data ... Browse Code »
    43

    of_parse_phandle_with_args() needs to return quite a bit of data. Rather
    than making each datum a separate **out_ argument, this patch creates
    struct of_phandle_args to contain all the returned data and reworks the
    user of the function. This patch also enables of_parse_phandle_with_args()
    to return the device node pointer for the phandle node.

    This patch also ends up being fairly major surgery to
    of_parse_handle_with_args(). The existing structure didn't work well
    when extending to use of_phandle_args, and I discovered bugs during testing.
    I also took the opportunity to rename the function to be like the
    existing of_parse_phandle().

    v2: - moved declaration of of_phandle_args to fix compile on non-DT builds
    - fixed incorrect index in example usage
    - fixed incorrect return code handling for empty entries

    Add an empty macro for of_match_node() that will save

    I have chosen to use a macro instead of a function to

    In fact, this "struct of_device_id *" first parameter
    is usualy not defined as well on non-dt builds.

  • 3bcbaf6e0   rtc: cmos: Add OF bindings ... Browse Code »

    This allows to load the OF driver based informations from the device
    tree. Systems without BIOS may need to perform some initialization.
    PowerPC creates a PNP device from the OF information and performs this
    kind of initialization in their private PCI quirk. This looks more
    generic.

    This patch also avoids registering the platform RTC driver on X86 if
    we have a device tree blob. Otherwise we would setup the device based
    on the hardcoded information in arch/x86 rather than the device tree
    based one.

  • 1976152fd   of: Fix comparison of "compatible" properties ... Browse Code »

    Commit 7c7b60cb87547b1664a4385c187f029bf514a737
    "of: put default string compare and #a/s-cell values into common header"

    Breaks various things on powerpc due to using strncasecmp instead of
    strcasecmp for comparing against "compatible" strings.

    This causes things like the 4xx PCI code to fail miserably due to the
    partial matches in code like this:

    for_each_compatible_node(np, NULL, "ibm,plb-pcix")
    ppc4xx_probe_pcix_bridge(np);
    for_each_compatible_node(np, NULL, "ibm,plb-pci")
    ppc4xx_probe_pci_bridge(np);

    It's not quite right to do partial name match. Entries in a compatible
    list are meant to be matched whole. If a device is compatible with both
    "foo" and "foo1", then the device should have both strings in its
    "compatible" property.

    This patch reverts powerpc and microblaze us to use strcasecmp.
