1 * Marvell Armada 380/XP Buffer Manager driver (BM)
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.
10 Optional properties (port):
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
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.
22 In order to see how to hook the BM to a given ethernet port, please
23 refer to Documentation/devicetree/bindings/net/marvell-armada-370-neta.txt.
