ARM: dts: bcm283x: Fix vc4's firmware bus DMA limitations
The bus is virtual and devices have to inherit their DMA constraints from the underlying interconnect. So add an empty dma-ranges property to the bus node, implying the firmware bus' DMA constraints are identical to its parent's. Fixes: 7dbe8c62ceeb ("ARM: dts: Add minimal Raspberry Pi 4 support") Signed-off-by: Nicolas Saenz Julienne <> Signed-off-by: Florian Fainelli <>
