   5 Required properties:
   6 - compatible : must be "mediatek,mt8173-smi-larb"
   7 - reg : the register and size of this local arbiter.
   8 - mediatek,smi : a phandle to the smi_common node.
   9 - power-domains : a phandle to the power domain of this local arbiter.
  10 - clocks : Must contain an entry for each entry in clock-names.
  11 - clock-names: must contain 2 entries, as follows:
  12   - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
  13             the register.
  14   - "smi" : It's the clock for transfer data and command.

  16 Example:
  17         larb1: larb@16010000 {
  18                 compatible = "mediatek,mt8173-smi-larb";
  19                 reg = <0 0x16010000 0 0x1000>;
  20                 mediatek,smi = <&smi_common>;
  21                 power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>;
  22                 clocks = <&vdecsys CLK_VDEC_CKEN>,
  23                          <&vdecsys CLK_VDEC_LARB_CKEN>;
  24                 clock-names = "apb", "smi";
