  • 6016a363f   of: unify phandle name in struct device_node ... Browse Code »

    In struct device_node, the phandle is named 'linux_phandle' for PowerPC
    and MicroBlaze, and 'node' for SPARC. There is no good reason for the
    difference, it is just an artifact of the code diverging over a couple
    of years. This patch renames both to simply .phandle.

    Note: the .node also existed in PowerPC/MicroBlaze, but the only user
    seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
    look like the assignment between .linux_phandle and .node is
    significantly different enough to warrant the separate code paths
    unless ibm,phandle properties actually appear in Apple device trees.

    I think it is safe to eliminate the old .node property and use
    phandle everywhere.

    The client->driver pointer can be NULL when i2c-device probing fails
    in i2c_new_device(). This patch adds the NULL checks for client->driver
    and return the error instead of blind assumption of driver availability.

  • ae31c1fbd   sound: remove driver_data direct access of struct device ... Browse Code »

    In the near future, the driver core is going to not allow direct access
    to the driver_data pointer in struct device. Instead, the functions
    dev_get_drvdata() and dev_set_drvdata() should be used. These functions
    have been around since the beginning, so are backwards compatible with
    all older kernel versions.

  • 5f17e79cd   ALSA: snd-aoa: handle master-amp if present ... Browse Code »

    Some machines have a master amp GPIO that needs to be toggled to
    get sound output, in addition to speaker/headphone/line-out amps.
    This makes snd-aoa handle it, if present in the device tree, thus
    making snd-aoa be able to output sound on PowerMac3,6, which was
    previously handled by snd-powermac which also doesn't use the
    master amp GPIO.

  • 45e513b68   ALSA: snd-aoa: handle older machines ... Browse Code »

    This patch changes snd-aoa to handle some older machines that are
    currently handled by snd-powermac. snd-aoa has a number of advantages
    though, notably it can autoload better and is generally a more modern
    driver.

    By hardcoding the accepted device-ids (last hunk of the patch) I'm
    trying to avoid regressions because this driver will otherwise load
    automatically and not let snd-powermac load. People who are unhappy
    with snd-powermac and have a device-id property in the device tree
    are encouraged to read this patch and make a patch to amend this as
    appropriate.

  • 7eff2e7a8   Driver core: change add_uevent_var to use a struct ... Browse Code »

    This changes the uevent buffer functions to use a struct instead of a
    long list of parameters. It does no longer require the caller to do the
    proper buffer termination and size accounting, which is currently wrong
    in some places. It fixes a known bug where parts of the uevent
    environment are overwritten because of wrong index calculations.

    Many thanks to Mathieu Desnoyers for finding bugs and improving the
    error handling.

  • 547ac2ae3   [ALSA] aoa i2sbus: Stop Apple i2s DMA gracefully ... Browse Code »

    This fixes the problem of getting extra bytes inserted at the
    beginning of a recording when using the Apple i2s interface and DBDMA
    controller. It turns out that we can't just abort the DMA; we have to
    let it stop at the end of a command, and then wait for the S7 bit to
    be set before turning off the DBDMA controller. Doing that for
    playback doesn't seem to be necessary, but doesn't hurt either.
    We use the technique used by the Darwin driver: make each transfer
    command branch to a stop command if the S0 status bit is set. Thus we
    can ask the DMA controller to stop at the end of the current command
    by setting S0.
    The interrupt routine now looks at and clears the status word of the
    DBDMA command ring. This is necessary so it can know when the DBDMA
    controller has seen that S0 is set, and so when it should look for the
    DBDMA controller being stopped and S7 being set. This also ended up
    simplifying the calculation in i2sbus_pcm_pointer.
    Tested on a 15 inch albook.
    [Addition by Johannes]
    I modified this patch and added the suspend/resume bits to it to get my
    powermac into a decent state when playing sound across suspend to disk
    that has a different bitrate from what the firmware programs the
    hardware to.
    I also added the SNDRV_PCM_INFO_JOINT_DUPLEX flag because it seemed the
    right thing to do and I was looking at the info stuff.
