    We don't care if the device_create_file calls fail, the driver will work
    just as well without them, so just issue a runtime warning.

    drivers/macintosh/therm_windtunnel.c: In function 'setup_hardware':
    drivers/macintosh/therm_windtunnel.c:268: warning: ignoring return value of 'device_create_file', declared with attribute warn_unused_result

  • b3e820968   i2c: Make i2c_del_driver a void function ... Browse Code »

    Make i2c_del_driver a void function, like all other driver removal
    functions. It always returned 0 even when errors occured, and nobody
    ever actually checked the return value anyway. And we cannot fail
    a module removal anyway.

  • 7eebde700   [POWERPC] Souped-up of_platform_device support ... Browse Code »

    This patch first splits of_device.c and of_platform.c, the later containing
    the bits relative to of_platform_device's. On the "breaks" side of things,
    drivers uisng of_platform_device(s) need to include asm/of_platform.h now
    and of_(un)register_driver is now of_(un)register_platform_driver.

    In addition to a few utility functions to locate of_platform_device(s),
    the main new addition is of_platform_bus_probe() which allows the platform
    code to trigger an automatic creation of of_platform_devices for a whole
    tree of devices.

    The function acts based on the type of the various "parent" devices encountered
    from a provided root, using either a default known list of bus types that can be
    "probed" or a passed-in list. It will only register devices on busses matching
    that list, which mean that typically, it will not register PCI devices, as
    expected (since they will be picked up by the PCI layer).

    This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
    and can be used by any embedded-type device as well.

  • 018a3d1db   [POWERPC] powermac: Constify & voidify get_property() ... Browse Code »

    Now that get_property() returns a void *, there's no need to cast its
    return value. Also, treat the return value as const, so we can
    constify get_property later.

    powermac platform & macintosh driver changes.

    Built for pmac32_defconfig, g5_defconfig

  • 2b48716d1   [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer needed ... Browse Code »

    Now that i2c_add_driver() doesn't need the module owner to be set by
    hand, we can delete it from the drivers. This patch catches all of the
    drivers that I found in the current tree (if a driver sets the .owner by
    hand, it's not a problem, just not needed.)

  • 8a9947552   [PATCH] i2c: Drop i2c_driver.flags, 2 of 3 ... Browse Code »

    Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
    can simply make it the default and drop the flag. If any driver really
    doesn't want to be notified when i2c adapters are added, that driver
    can simply omit to set .attach_adapter. This approach is also more
    robust as it prevents accidental NULL pointer dereferences.

  • 0365ba7fb   [PATCH] ppc64: SMU driver update & i2c support ... Browse Code »

    The SMU is the "system controller" chip used by Apple recent G5 machines
    including the iMac G5. It drives things like fans, i2c busses, real time
    clock, etc...

    The current kernel contains a very crude driver that doesn't do much more
    than reading the real time clock synchronously. This is a completely
    rewritten driver that provides interrupt based command queuing, a userland
    interface, and an i2c/smbus driver for accessing the devices hanging off
    the SMU i2c busses like temperature sensors. This driver is a basic block
    for upcoming work on thermal control for those machines, among others.

  • 5e6557722   [PATCH] openfirmware: generate device table for userspace ... Browse Code »

    This converts the usage of struct of_match to struct of_device_id,
    similar to pci_device_id. This allows a device table to be generated,
    which can be parsed by depmod(8) to generate a map file for module
    loading.

    In order for hotplug to work with macio devices, patches to
    module-init-tools and hotplug must be applied. Those patches are

  • b3d5496ea   [PATCH] I2C: Kill address ranges in non-sensors i2c chip drivers ... Browse Code »

    Some months ago, you killed the address ranges mechanism from all
    sensors i2c chip drivers (both the module parameters and the in-code
    address lists). I think it was a very good move, as the ranges can
    easily be replaced by individual addresses, and this allowed for
    significant cleanups in the i2c core (let alone the impressive size
    shrink for all these drivers).

    Unfortunately you did not do the same for non-sensors i2c chip drivers.
    These need the address ranges even less, so we could get rid of the
    ranges here as well for another significant i2c core cleanup. Here comes
    a patch which does just that. Since the process is exactly the same as
    what you did for the other drivers set already, I did not split this one
    in parts.

    A documentation update is included.

    The change saves 308 bytes in the i2c core, and an average 1382 bytes
    for chip drivers which use I2C_CLIENT_INSMOD, 126 bytes for those which
    do not.

    This change is required if we want to merge the sensors and non-sensors
    i2c code (and we want to do this).

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
