    Subject[PATCH v2 0/3] ASoC: add support for audio on iPaq hx4700
    Ok, here's patches adding audio support for good ole iPAQ hx4700: ak4641
    codec, hx4700 machine sound driver and some glue platform code.
    It took quite longer to make v2 than I expected, but it's finally here.
    Sorry for such late submission in this release cycle, but if it's not ready
    yet, no big deal - it certainly can wait for 2.6.41.

    v1 of these patches can be found here:

    Current patchset is based on next-20110513 (it also can be applied to
    2.6.39-rc7 after slight adjustment of Kconfig/Makefile chunks)

    Latest version of these patches were only slightly tested on top of 2.6.39-rc7
    (-next is tested compile-only, as it doesn't boot due to some unrelated bugs),
    but all basic operations like playback, recording, EQ, Speaker, Mic Sidetone
    seem to work.

    Changes from v1:

    AK4641 codec:

    * '-codec' is removed from 'ak4641-codec' platform device name
    * SNDRV_PCM_RATE_8000_48000 macro now used instead of explicit freqs listing
    * Unneeded ifdef's on CONFIG_I2C are removed
    * Missing "Volume" added to names of volume controls, ditto for switches
    * TLV information is added to various volume controls
    * Enum control doesn't use indexed array of strings anymore
    * Enum controls like 'Mic Boost +20dB/0dB' are turned into volume controls
    * Deemphasis control is converted from enum to switch with automatic
    detection of optimal deemphasis value depending on current playback frequency
    * Check for wrong fs value is added to hw_params for HiFi DAI
    (that actually uncovered bug in hx4700 machine driver - it never set
    sysclk for the codec. Sound worked properly this way due to strange
    coincidence: both default fs in codec driver and divider in PXA i2s hardware
    were equal 256)
    * empty hw_params() function for Voice DAI is removed. Looks like that
    samplerate of Voice ADC/DAC can't be controlled by software at all, only
    format of samples. This Voice DAC/ADC are designed to be connected to
    Bluetooth chip, so I suspect codec gets sampling frequency directly
    from it.
    * Names of mic sidetone controls are adjusted
    * 'Left/Right Out Enable' DAPM controls are turned into ordinary ones
    * Mute code readability is slightly improved (based on Axel Lin's patch
    for ak4535 - commit cca67a3668)
    * My copyright is added to file, so people won't blame Harald for all the
    bugs I added during multicomponent conversion and other cleanup :)
    * Power/reset GPIOs are now handled in set_bias_level(), so codec is
    powered only when needed.

    HX4700 sound:

    * Setting of codec's sysclk is added to hw_params()

    HX4700 platform:

    * No changes
