I don't think this makes any functional difference though, and we don't seem to have it on other recent SoCs... > + reg = <0 0x01dc4000 0 0x28000>; > + > + interrupts = <GIC_SPI 272 IRQ_TYPE_LEVEL_HIGH>; > + > + #dma-cells = <1>; > + > + iommus = <&apps_smmu 0x480 0>, > + <&apps_smmu 0x481 0>; Should be same as <&apps_smmu 0x480 0x1> (0x1 is applied as mask to the SID, and 0x481 & ~0x1 = 0x480). > + > + qcom,ee = <0>; > + qcom,controlled-remotely; Please add "num-channels" and "qcom,num-ees". Otherwise you risk causing crashes if the interconnect listed below isn't up (anymore) when the driver probes the device.
