I'm not sure as I couldn't find more details about APB, ATB and AXI on G12A: - APB and ATB may be needed by the CoreSight bindings (Documentation/devicetree/bindings/arm/coresight.txt) - AXI may be needed by the VPU driver (the S912 datasheet mentions in OSD1_AFBCD_ENABLE: "id_fifo_thrd : unsigned , default = 64, axi id fifo threshold") if you don't know either then I'm fine with skipping them for now, we can still export them later.
