5Required properties:
6- compatible : must be one of :
7		"mediatek,mt2701-smi-larb"
8		"mediatek,mt2712-smi-larb"
9		"mediatek,mt6779-smi-larb"
10		"mediatek,mt7623-smi-larb", "mediatek,mt2701-smi-larb"
11		"mediatek,mt8167-smi-larb"
12		"mediatek,mt8173-smi-larb"
13		"mediatek,mt8183-smi-larb"
14- reg : the register and size of this local arbiter.
15- mediatek,smi : a phandle to the smi_common node.
16- power-domains : a phandle to the power domain of this local arbiter.
17- clocks : Must contain an entry for each entry in clock-names.
18- clock-names: must contain 2 entries, as follows:
19  - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
20	    the register.
21  - "smi" : It's the clock for transfer data and command.
22  and this optional clock name:
23  - "gals": the clock for GALS(Global Async Local Sync).
24  Here is the list which has this GALS: mt8183.
