* Marvell Armada 380/XP Buffer Manager driver (BM) Required properties: - compatible: should be "marvell,armada-380-neta-bm". - reg: address and length of the register set for the device. - clocks: a pointer to the reference clock for this device. - internal-mem: a phandle to BM internal SRAM definition. Optional properties (port): - pool<0 : 3>,capacity: size of external buffer pointers' ring maintained in DRAM. Can be set for each pool (id 0 : 3) separately. The value has to be chosen between 128 and 16352 and it also has to be aligned to 32. Otherwise the driver would adjust a given number or choose default if not set. - pool<0 : 3>,pkt-size: maximum size of a packet accepted by a given buffer pointers' pool (id 0 : 3). It will be taken into consideration only when pool type is 'short'. For 'long' ones it would be overridden by port's MTU. If not set a driver will choose a default value. In order to see how to hook the BM to a given ethernet port, please refer to Documentation/devicetree/bindings/net/marvell-armada-370-neta.txt. Example: - main node: bm: bm@c8000 { compatible = "marvell,armada-380-neta-bm"; reg = <0xc8000 0xac>; clocks = <&gateclk 13>; internal-mem = <&bm_bppi>; pool2,capacity = <4096>; pool1,pkt-size = <512>; }; - internal SRAM node: bm_bppi: bm-bppi { compatible = "mmio-sram"; reg = ; ranges = <0 MBUS_ID(0x0c, 0x04) 0 0x100000>; #address-cells = <1>; #size-cells = <1>; clocks = <&gateclk 13>; };
