1257629b07 [ARM] pxa: fix pxa27x_udc default pullup GPIO
Currently, pxa27x_udc tries to use GPIO 0 as D+ pullup if not
explicitly configured. Default to an invalid GPIO (-1) instead.

866bd43581 [ARM] pxa: enable GPIO receivers after configuring pins
'mach-pxa' platforms currently rely on a bootloader to setup GPIO pins
and clear RDH (to enable inputs).

A kernel loaded by a 'minimal' bootloader, that doesn't touch any pins,
will not function correctly; inputs will remain disabled, even after the
pins are configured. The following change fixes the issue and has been
verified on Gumstix Verdex XL6P and a custom PXA270 platform.

15fbc93857 [ARM] pxa/zylonite: fix the issue of unused SDATA_IN_1 pin get AC97 not working
GPIO17_SDATA_IN_1 and GPIO36_SDATA_IN_1 are originally designed for the 2nd
codec but unused on the board, yet they are initialized incorrectly by the
bootloader as the SDATA_IN_1 alternate function, thus causing AC97 fail to
work. Fix this issue by configuring these pins as normal GPIO to avoid the
noise from these pins being treated as signals from the 2nd codec.

cc8d2730ad [ARM] pxa/mioa701: use GPIO95 as AC97 reset line
MioA701 board's GPIO95 is the AC97 line. The other GPIO113
is not connected to the sound chip, but to the GSM chip as a
wakeup line.

It happens that when the pxa2xx_ac97 driver reconfigures the
gpio as an "out gpio" for AC97 reset (bug workaround), it
hangs the GSM chip.

As AC97 platform data now enables to specify the AC97 reset
line, use it.

eae17754ab [ARM] pxa: merge AC97 platform data structures
Currently there are two possible platform datas for the PXA AC97 driver:
one supported by the generic AC97 driver only which provides callbacks
to allow board-specific configuration at stream startup and teardown,
and another for pxa2xx-ac97-lib which allows configuration of the reset
GPIO for PXA2xx CPUs.

Obviously this won't actually work when using the generic AC97 driver
since the drivers will attempt to parse the platform data in both
formats. Fix this by merging the two structures.
