+title: Allwinner Memory Bus (MBUS) controller
+
+maintainers:
+ - Chen-Yu Tsai <wens@csie.org>
+ - Maxime Ripard <mripard@kernel.org>
+
+description: |
+ The MBUS controller drives the MBUS that other devices in the SoC
+ will use to perform DMA. It also has a register interface that
+ allows to monitor and control the bandwidth and priorities for
+ masters on that bus.
+
+ Each device having to perform their DMA through the MBUS must have
+ the interconnects and interconnect-names properties set to the MBUS
+ controller and with "dma-mem" as the interconnect name.
+
+properties:
+ "#interconnect-cells":
