1 SMI (Smart Multimedia Interface) Common

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

16 Example:
17 smi_common: smi@14022000 {
18 compatible = "mediatek,mt8173-smi-common";
19 reg = <0 0x14022000 0 0x1000>;
20 power-domains = <&scpsys MT8173_POWER_DOMAIN_MM>;
21 clocks = <&mmsys CLK_MM_SMI_COMMON>,
22 <&mmsys CLK_MM_SMI_COMMON>;
23 clock-names = "apb", "smi";
24 };
