I could imagine the original intention was to be backward compatible.

Indeed, if this call is not optional, systems using AT8030 and lacking a
reset line on DT will have their behaviour affected.
NOTE: they would still work because even if this driver fails to bind a
generic one will take over.

Best regards,
