Say Y if you want to run with the AT32 SSC generating the BCLK

Say Y if you want to run with the AT32 SSC generating the BCLK
and FRAME signals on the PlayPaq. Unless you want to play
with the AT32 as the SSC master, you probably want to say N here,
as this will give you better sound quality.

Normally ASoC codec drivers are only built if a machine driver which
uses them is also built since they are only usable with a machine
driver. Selecting this option will allow these drivers to be built
without an explicit machine driver for test and development purposes.
Support for the bus types used to access the codecs to be built must
be selected separately.
If unsure select "N".

/*
ALSA SOC usually puts the device in standby mode when it's not used
for sometime. If you define POWER_OFF_ON_STANDBY the driver will
turn off the ADC/DAC when this callback is invoked and turn it back
on when needed. Unfortunately this will result in a very light bump
(it can be audible only with good earphones). If this bothers you
just comment this line, you will have slightly higher power
consumption . Please note that sending the L3 command for ADC is
enough to make the bump, so it doesn't make difference if you
completely take off power from the codec.
