8 title: SMI (Smart Multimedia Interface) Common
11   - Yong Wu <yong.wu@mediatek.com>
16   MediaTek SMI have two generations of HW architecture, here is the list
19   generation 2: mt2712, mt6779, mt8167, mt8173, mt8183 and mt8192.
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.
