Is there an external pull?
I think no external pull. In trogdor mentioned bias-pull-down but you
suggested to remove it.
Maybe on trogdor there was an external pull inside the amp that this pin
is connected to? Usually we have a comment like /* Has external
pull-{up,down} */ so please add that here depending on which way the
pull goes.

As per Anderson suggestion we removed bias-pull-down. Actually, it's up-streamed for same platform in sc7280-herobrine.dtsi.

We will fallow the same. It contains bias-pull-down.
