16 MediaTek SMI have two generations of HW architecture, here is the list
21 There's slight differences between the two SMI, for generation 2, the
23 for generation 1, the register is at smi ao base(smi always on register
24 base). Besides that, the smi async clock should be prepared and enabled for
25 SMI generation 1 to transform the smi clock into emi clock domain, but that is
26 not needed for SMI generation 2.
