The CSID in SM8550 is gen3, it has new register offset and new
functionality. The buf done irq,register update and reset are
moved to CSID gen3. And CSID gen3 has a new register block which
is named as CSID top, it controls the output of CSID, since the
CSID can connect to Sensor Front End (SFE) or original VFE, the
register in top block is used to control the HW connection.
