Should this also be added to sc7280-herobrine-crd.dts?

The '@1' is the address of the lpass CPU DAI, which doesn't seem correct
here. As I brought up on v7 [1] I think this value isn't even necessarily
unique, a SoC could have multiple IP blocks with audio buses, each with
their own DAI address space. The binding (currently) requires an
'address'/id, rather than using the CPU DAI id I suggest to enumerate the
links linearly, starting with 0.

The binding requires a 'reg' property, even though it isn't used (also
discussed on v7). I think the 'reg' property should be removed from the
binding and the DTs that use it, but maybe that should be done in a
separate series. In the meantime the value should match that of the
node.

Okay. for now will revert this change. and will take care your
