#GPIO actions are expressed as a binary string, a sequence of one or more 4-BYTE tuplets 
#      (beyond the initial "1" type value required for registry entry). 
#    The 4 fields (each a BYTE in length) in each tuplet are:
#      { (Codec CID), (GPIO pin number), (GPIO action code), (Pin assertion sense) }
#    The "Codec CID" must match a recognized CODEC (by CID) on the AC97 link, and the "GPIO pin number"
#      must be a valid GPIO pin index for that CODEC.  If GPIO is enabled, there must be at least one
#      well-formed specification.
#
#    GPIO Pin number = GPIO0=00, GPIO1=01, GPIO2=02, GPIO3=03, EAPD=04, VREF=05
#
#    The valid values for "GPIO action code" (and implicit directions, GPI or GPO) are:
#    0=    Disable software equalization             (GPIDisableSoftwareEQ)        (GPI)
#    1=    Mute master volume, pins 35/36            (GPIMuteMasterVolume)         (GPI)
#    2=    DRM Digital Disable State                 (GPODRMDigitalDisable)        (GPO)
#    3=    GPI Mic Select                            (GPIMicSelect)
#    4=    Mutes headphone volume, pins 39/41        (GPIMuteHPVolume) 
#    5=    GPI to GPO                                (GPIToGPO)
#    6=    Mute codec pins according to mask in reg64h (9758 only)	(GPIMuteCodecPins)
#
#    "Pin assertion sense" maps the CODEC pin state to the logical assertion state of the action
#        0 means the action is asserted on a sensed (or driven for GPO) CODEC pin value 0
#        1 (non-zero) means asserted on sensed (driven) CODEC pin value 1.
