- reg : Address space for the configuration registers
- interrupts : Interrupt specifier for the IOMMU instance
- interrupt-names : Interrupt name for the IOMMU instance
+- clocks : Iommu share clocks with master, to make map buffer success
+ when master disable clocks, iommu should control related
+ clocks itself
+- clock-names : Iommu related clock name, it should be "aclk" and "hclk" on
+ RK3399 SoC platform
+- power-domains : Iommu share power-domains with master, it have the same purpose
+ with the clocks
- #iommu-cells : Should be <0>. This indicates the iommu is a
"single-master" device, and needs no additional information
to associate with its master device. See:
Example:
- vopl_mmu: iommu@ff940300 {
+ vopl_mmu: iommu@ff8f3f00 {
compatible = "rockchip,iommu";
- reg = <0xff940300 0x100>;
- interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
+ reg = <0x0 0xff8f3f00 0x0 0x100>;
+ interrupts = <GIC_SPI 119 IRQ_TYPE_LEVEL_HIGH 0>;
interrupt-names = "vopl_mmu";
+ clocks = <&cru ACLK_VOP1>, <&cru HCLK_VOP1>;
+ clock-names = "aclk", "hclk";
+ power-domains = <&power RK3399_PD_VOPL>;
#iommu-cells = <0>;
