In most cases, many codecs already supports jack detection, previouslly,
we need to create a customized machine driver every time.
Hence, the simple-card need to support use them dynamically via parse dts

simple-card is not so simple...
I think this information be part of the codec node if the codec
provides the functionality. The binding should not be different whether
a codec is part of simple-card or not. Also, I would make all these just
boolean props.
Yes, these things seem like make simple-card becomes more complicated,
and the generic jack detection method is still a problem currently.
Hi Mark, the other question here, how do we make sense to use the
simple-card to call the "snd_soc_dai_set_pll" if the codec (like da7219)
requires do this?
Thanks.
