    5 Required 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.
   25 
   26 Required property for mt2701, mt2712, mt6779, mt7623 and mt8167:
   27 - mediatek,larb-id :the hardware id of this larb.
   28 
   29 Example:
   30         larb1: larb@16010000 {
   31                 compatible = "mediatek,mt8173-smi-larb";
   32                 reg = <0 0x16010000 0 0x1000>;
   33                 mediatek,smi = <&smi_common>;
   34                 power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>;
   35                 clocks = <&vdecsys CLK_VDEC_CKEN>,
   36                          <&vdecsys CLK_VDEC_LARB_CKEN>;
   37                 clock-names = "apb", "smi";
   38         };
   39 
   40 Example for mt2701:
   41         larb0: larb@14010000 {
   42                 compatible = "mediatek,mt2701-smi-larb";
   43                 reg = <0 0x14010000 0 0x1000>;
   44                 mediatek,smi = <&smi_common>;
   45                 mediatek,larb-id = <0>;
   46                 clocks = <&mmsys CLK_MM_SMI_LARB0>,
   47                          <&mmsys CLK_MM_SMI_LARB0>;
   48                 clock-names = "apb", "smi";
   49                 power-domains = <&scpsys MT2701_POWER_DOMAIN_DISP>;
   50         };
