-Allwinner Memory Bus (MBUS) controller
-
-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.
-
-Required properties:
- - compatible: Must be one of:
- - allwinner,sun5i-a13-mbus
- - allwinner,sun8i-h3-mbus
- - reg: Offset and length of the register set for the controller
- - clocks: phandle to the clock driving the controller
- - dma-ranges: See section 2.3.9 of the DeviceTree Specification
- - #interconnect-cells: Must be one, with the argument being the MBUS
- port ID
-
-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.
-
-Example:
-
-mbus: dram-controller@1c01000 {
- compatible = "allwinner,sun5i-a13-mbus";
- reg = <0x01c01000 0x1000>;
- clocks = <&ccu CLK_MBUS>;
- dma-ranges = <0x00000000 0x40000000 0x20000000>;
- #interconnect-cells = <1>;
-};
-
-fe0: display-frontend@1e00000 {
- compatible = "allwinner,sun5i-a13-display-frontend";
- ...
- interconnects = <&mbus 19>;
- interconnect-names = "dma-mem";
-};
