Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware is largely based on the full-blown SYSTEMPORT and differs in the following: - no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since we are always interfaced to an Ethernet switch which is fully Ethernet compliant shortcuts could be made - 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt controller bank - slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*) - 256 RX descriptors (512 words) and 256 TX descriptors (not visible) As a consequence of these two things, update the code paths accordingly to differentiate the full-blown from the light version.

* Broadcom BCM7xxx Ethernet Systemport Controller (SYSTEMPORT)
|
|
|
|
Required properties:
|
|
- compatible: should be one of:
|
|
"brcm,systemport-v1.00"
|
|
"brcm,systemportlite-v1.00" or
|
|
"brcm,systemport"
|
|
- reg: address and length of the register set for the device.
|
|
- interrupts: interrupts for the device, first cell must be for the rx
|
|
interrupts, and the second cell should be for the transmit queues. An
|
|
optional third interrupt cell for Wake-on-LAN can be specified
|
|
- local-mac-address: Ethernet MAC address (48 bits) of this adapter
|
|
- phy-mode: Should be a string describing the PHY interface to the
|
|
Ethernet switch/PHY, see Documentation/devicetree/bindings/net/ethernet.txt
|
|
- fixed-link: see Documentation/devicetree/bindings/net/fixed-link.txt for
|
|
the property specific details
|
|
|
|
Optional properties:
|
|
- systemport,num-tier2-arb: number of tier 2 arbiters, an integer
|
|
- systemport,num-tier1-arb: number of tier 1 arbiters, an integer
|
|
- systemport,num-txq: number of HW transmit queues, an integer
|
|
- systemport,num-rxq: number of HW receive queues, an integer
|
|
|
|
Example:
|
|
ethernet@f04a0000 {
|
|
compatible = "brcm,systemport-v1.00";
|
|
reg = <0xf04a0000 0x4650>;
|
|
local-mac-address = [ 00 11 22 33 44 55 ];
|
|
fixed-link = <0 1 1000 0 0>;
|
|
phy-mode = "gmii";
|
|
interrupts = <0x0 0x16 0x0>,
|
|
<0x0 0x17 0x0>;
|
|
};
