9		"mediatek,mt8173-smi-larb"
10- reg : the register and size of this local arbiter.
11- mediatek,smi : a phandle to the smi_common node.
12- power-domains : a phandle to the power domain of this local arbiter.
13- clocks : Must contain an entry for each entry in clock-names.
14- clock-names: must contain 2 entries, as follows:
