net: dsa: bcm_sf2: Call setup during switch resume

2018-10-11T22:19:54+00:00

There is no reason to open code what the switch setup function does, in
fact, because we just issued a switch reset, we would make all the
register get their default values, including for instance, having unused
port be enabled again and wasting power and leading to an inappropriate
switch core clock being selected.

net: dsa: bcm_sf2: Fix unbind ordering

2018-10-11T22:19:40+00:00

The order in which we release resources is unfortunately leading to bus
errors while dismantling the port. This is because we set
priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now
permissible to clock gate the switch. Later on, when dsa_slave_destroy()
comes in from dsa_unregister_switch() and calls
dsa_switch_ops::port_disable, we perform the same dismantling again, and
this time we hit registers that are clock gated.

Make sure that dsa_unregister_switch() is the first thing that happens,
which takes care of releasing all user visible resources, then proceed
with clock gating hardware. We still need to set priv->wol_ports_mask to
0 to make sure that an enabled port properly gets disabled in case it
was previously used as part of Wake-on-LAN.

net: dsa: b53: Keep CPU port as tagged in all VLANs

2018-10-05T04:52:49+00:00

Commit c499696e7901 ("net: dsa: b53: Stop using dev->cpu_port
incorrectly") was a bit too trigger happy in removing the CPU port from
the VLAN membership because we rely on DSA to program the CPU port VLAN,
which it does, except it does not bother itself with tagged/untagged and
just usese untagged.

Having the CPU port "follow" the user ports tagged/untagged is not great
and does not allow for properly differentiating, so keep the CPU port
tagged in all VLANs.

net: dsa: rtl8366rb: Support port 4 (WAN)

2018-08-09T21:15:00+00:00

The totally undocumented IO mode needs to be set to enumerator
0 to enable port 4 also known as WAN in most configurations,
for ordinary traffic. The 3 bits in the register come up as
010 after reset, but need to be set to 000.

The Realtek source code contains a name for these bits, but
no explanation of what the 8 different IO modes may be.

Set it to zero for the time being and drop a comment so
people know what is going on if they run into trouble. This
"mode zero" works fine with the D-Link DIR-685 with
RTL8366RB.

net: dsa: mv88e6xxx: Add SERDES phydev_mac_change up for 6390

2018-08-09T18:08:20+00:00

phylink wants to know when the MAC layers notices a change in the
link. For the 6390 family, this is a change in the SERDES state.

Add interrupt support for the SERDES interface used to implement
SGMII/1000Base-X/2500Base-X. This is currently limited to ports 9 and
10. Support for the 10G SERDES and other ports will be added later,
building on this basic framework.
