-The hardware block diagram please check bindings/iommu/mediatek,iommu.txt
-
-Required properties:
-- compatible : must be one of :
- "mediatek,mt2701-smi-larb"
- "mediatek,mt2712-smi-larb"
- "mediatek,mt6779-smi-larb"
- "mediatek,mt7623-smi-larb", "mediatek,mt2701-smi-larb"
- "mediatek,mt8167-smi-larb"
- "mediatek,mt8173-smi-larb"
- "mediatek,mt8183-smi-larb"
-- reg : the register and size of this local arbiter.
-- mediatek,smi : a phandle to the smi_common node.
-- power-domains : a phandle to the power domain of this local arbiter.
-- clocks : Must contain an entry for each entry in clock-names.
-- clock-names: must contain 2 entries, as follows:
- - "apb" : Advanced Peripheral Bus clock, It's the clock for setting
- the register.
- - "smi" : It's the clock for transfer data and command.
- and this optional clock name:
- - "gals": the clock for GALS(Global Async Local Sync).
- Here is the list which has this GALS: mt8183.
-
-Required property for mt2701, mt2712, mt6779, mt7623 and mt8167:
-- mediatek,larb-id :the hardware id of this larb.
-
-Example:
- larb1: larb@16010000 {
- compatible = "mediatek,mt8173-smi-larb";
- reg = <0 0x16010000 0 0x1000>;
- mediatek,smi = <&smi_common>;
- power-domains = <&scpsys MT8173_POWER_DOMAIN_VDEC>;
- clocks = <&vdecsys CLK_VDEC_CKEN>,
- <&vdecsys CLK_VDEC_LARB_CKEN>;
- clock-names = "apb", "smi";
- };
-
-Example for mt2701:
- larb0: larb@14010000 {
- compatible = "mediatek,mt2701-smi-larb";
- reg = <0 0x14010000 0 0x1000>;
- mediatek,smi = <&smi_common>;
- mediatek,larb-id = <0>;
- clocks = <&mmsys CLK_MM_SMI_LARB0>,
- <&mmsys CLK_MM_SMI_LARB0>;
- clock-names = "apb", "smi";
- power-domains = <&scpsys MT2701_POWER_DOMAIN_DISP>;
- };
