5Required properties:
6- compatible : must be one of :
7		"mediatek,mt2701-smi-larb"
8		"mediatek,mt2712-smi-larb"
9		"mediatek,mt7623-smi-larb", "mediatek,mt2701-smi-larb"
10		"mediatek,mt8173-smi-larb"
11		"mediatek,mt8183-smi-larb"
12- reg : the register and size of this local arbiter.
13- mediatek,smi : a phandle to the smi_common node.
14- power-domains : a phandle to the power domain of this local arbiter.
15- clocks : Must contain an entry for each entry in clock-names.
16- clock-names: must contain 2 entries, as follows:
17  - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
18	    the register.
19  - "smi" : It's the clock for transfer data and command.
20  and this optional clock name:
21  - "gals": the clock for GALS(Global Async Local Sync).
22  Here is the list which has this GALS: mt8183.
23
24Required property for mt2701, mt2712 and mt7623:
25- mediatek,larb-id :the hardware id of this larb.
