No, that's wrong, at least for the CPU pmu node. First, you need two of them (one for the A55s, one for the A75s). Then you need to partition the corresponding PPI so that they can be described as separate affinity sets. Finally, this implies that #interrupt-cells goes up to 4, and all the interrupts directly routed to the GIC must be updated. You should have something like this: &gic { ppi-partitions { cluster0: interrupt-partition-0 { affinity = <&cpu0 &cpu1 &cpu2 &cpu3 &cpu4 &cpu5>; }; cluster1: interrupt-partition-1 { affinity = <&cpu6 &cpu7>; }; }; pmu_a55 { compatible = "arm,cortex-a55-pmu", "arm,armv8-pmuv3"; interrupts = <GIC_PPI 7 IRQ_TYPE_LEVEL_LOW &cluster0>; }; pmu_a75 { compatible = "arm,cortex-a75-pmu", "arm,armv8-pmuv3"; interrupts = <GIC_PPI 7 IRQ_TYPE_LEVEL_LOW &cluster1>; }; Please see the rk3399 usage of the binding, as it is the canonical example. > >> >>> + #address-cells = <2>; >>> + #size-cells = <2>; >>> + #redistributor-regions = <1>; >> >> This is the default, so this can be omitted. >> > > Got it, will remove it in v3. > >>> + interrupt-parent = <&gic>; >>> + interrupt-controller; >>> + reg = <0 0x0c000000 0 0x40000>, /* GICD */ >>> + <0 0x0c040000 0 0x200000>, /* GICR */ >>> + <0 0x0c400000 0 0x2000>, /* GICC */ >>> + <0 0x0c410000 0 0x1000>, /* GICH */ >>> + <0 0x0c420000 0 0x2000>; /* GICV */ >> >> Where do the last 3 ranges come from?

Will check rk3399 and fix our part. Thanks for reviewing.

By the way, while talking about basic support. Do you have any detailed plans to upstream this SoC? We already have mt6755 and mt6795 which didn't get much further then the most basic support. More or less the same holds for mt6797. While I'm thrilled to see efforts done by MediaTek to get the chips upstream, I'm not really happy to add a new SoC every now and then without seeing much progress on the overall enablement of new peripherals. I know on mt6797 we would need pmic-regulator to be able to upstream the MMC driver. Without that the available board [1] is of little use. I wonder if all this other SoCs have a really different PMIC and MMC. I'm not saying that I want you to upstream these for mt6797. What I wanted to express is my hope that by upstreaming more and more peripherals of the mt67xx line, we will little by little get to a nice support in mainline kernel. That's what motivated my question about your plans for upstreaming the SoC.
