1* Marvell Armada 380/XP Buffer Manager driver (BM)
2
3Required properties:
4
5- compatible: should be "marvell,armada-380-neta-bm".
6- reg: address and length of the register set for the device.
7- clocks: a pointer to the reference clock for this device.
8- internal-mem: a phandle to BM internal SRAM definition.
9
10Optional properties (port):
11
12- pool<0 : 3>,capacity: size of external buffer pointers' ring maintained
13  in DRAM. Can be set for each pool (id 0 : 3) separately. The value has
14  to be chosen between 128 and 16352 and it also has to be aligned to 32.
15  Otherwise the driver would adjust a given number or choose default if
16  not set.
17- pool<0 : 3>,pkt-size: maximum size of a packet accepted by a given buffer
18  pointers' pool (id 0 : 3). It will be taken into consideration only when pool
19  type is 'short'. For 'long' ones it would be overridden by port's MTU.
20  If not set a driver will choose a default value.

22In order to see how to hook the BM to a given ethernet port, please

25Example:
26
27- main node:
28
29bm: bm@c8000 {
30	compatible = "marvell,armada-380-neta-bm";
31	reg = <0xc8000 0xac>;
32	clocks = <&gateclk 13>;
33	internal-mem = <&bm_bppi>;
34	pool2,capacity = <4096>;
35	pool1,pkt-size = <512>;
36};
37
38- internal SRAM node:
39
40bm_bppi: bm-bppi {
41	compatible = "mmio-sram";
42	reg = <MBUS_ID(0x0c, 0x04) 0 0x100000>;
43	ranges = <0 MBUS_ID(0x0c, 0x04) 0 0x100000>;
44	#address-cells = <1>;
45	#size-cells = <1>;
46	clocks = <&gateclk 13>;
47};
