net: dsa: mv88e6060: replace magic values with register defines

2015-11-16T01:16:16+00:00

To align with the mv88e6xxx code, use the register defines to
access all the register addresses and bit fields.

net: dsa: mv88e6060: add register defines header file

2015-11-16T01:16:16+00:00

To align with the mv88e6xxx code, add a similar header file
with all the register defines.
The file is based on the mv88e6xxx header for coherency.

net: dsa: mv88e6060: use the correct bit shift for mac0

2015-11-16T01:16:16+00:00

According to the mv88e6060 datasheet, the first mac byte must
be at position 9 instead of 8 since the bit 8 is used to select
if the mac address must differ for each port for Pause frames.
Use the correct shift and set the same mac address for all port.

net: dsa: mv88e6060: use the correct MaxFrameSize bit

2015-11-16T01:16:16+00:00

According to the mv88e6060 datasheet, the MaxFrameSize bit position
is 10 instead of 11 which is reserved.
Use the bit correctly to setup max frame size to 1536.

net: dsa: mv88e6060: use the correct InitReady bit

2015-11-16T01:16:15+00:00

According to the mv88e6060 datasheet, the InitReady bit position
is 11 and the polarity is inverted.
Use the bit correctly to detect the end of initialization.

net: dsa: mv88e6060: remove poll_link callback

2015-11-16T01:16:15+00:00

As of mv88e6xxx remove the poll_link callback since the link
state change polling is now handled by the phylib.

Tested on a mv88e6060 B0 device with a TI DM816X SoC.

net: dsa: mv88e6xxx: isolate unbridged ports

2015-11-05T18:37:23+00:00

The DSA documentation specifies that each port must be capable of
forwarding frames to the CPU port. The last changes on bridging support
for the mv88e6xxx driver broke this requirement for non-bridged ports.

So as for the bridged ports, reserve a few VLANs (4000+) in the switch
to isolate ports that have not been bridged yet.

By default, a port will be isolated with the CPU and DSA ports. When the
port joins a bridge, it will leave its reserved port. When it is removed
from a bridge, it will join its reserved VLAN again.

net: dsa: mv88e6xxx: include DSA ports in VLANs

2015-11-03T16:30:17+00:00

DSA ports must be members of a VLAN in order to ensure frame bridging
between chained switch chips.

Thus tag them in addition to the CPU port when adding a VLAN, and skip
them when deleting a VLAN and reporting VLAN members.

Also use the UNMODIFIED egress policy, so that frames egress on these
ports as they ingress, tagged or untagged.

net: dsa: mv88e6xxx: disable SA learning for DSA and CPU ports

2015-11-03T16:29:57+00:00

Frames with DSA headers passing to/from the CPU were taking place in the
MAC learning on these ports, resulting in incorrect ATU entries. Disable
learning on these ports.

net: dsa: mv88e6xxx: lookup switch name

2015-11-02T20:54:13+00:00

All the mv88e6xxx drivers use the exact same code in their probe
function to lookup the switch name given its ID. Thus introduce a
mv88e6xxx_switch_id structure and a mv88e6xxx_lookup_name function in
the common mv88e6xxx code.

In the meantime make __mv88e6xxx_reg_{read,write} static since we do not
need to expose these low-level r/w routines anymore.
