net: dsa: add support for ksz9897 ethernet switch

2018-08-16T19:24:55+00:00

ksz9477 is superset of ksz9xx series, driver just works
out of the box for ksz9897 chip with this patch.

net: dsa: mv88e6xxx: missing unlock on error path

2018-08-14T17:08:07+00:00

We added a new error path, but we need to drop the lock before we return.

We are trying to test if these flags are set but there are some && vs &
typos.

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: Re-setup interrupts on CMODE change.

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

When a port changes CMODE, the SERDES interface being used can change.
Disable interrupts for the old SERDES interface, and enable interrupts
on the new.

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.

net: dsa: mv88e6xxx: link mv88e6xxx_port to mv88e6xxx_chip

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

An up coming change will register interrupts for individual switch
ports, using the mv88e6xxx_port as the interrupt context information.
Add members to the mv88e6xxx_port structure so we can link it back to
the mv88e6xxx_chip member the port belongs to and the port number of
the port.

net: dsa: mv88e6xxx: Power on/off SERDES on cmode change

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

The 6390 family has a number of SERDES interfaces per port. When the
cmode changes, eg 1000Base-X to XAUI, the SERDES interface in use will
also change. Power down the old SERDES interface and power up the new
SERDES interface.

net: dsa: mv88e6xxx: Cache the port cmode

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

The ports CMODE indicates the type of link between the MAC and the
PHY. It is used often in the SERDES code. Rather than read it each
time, cache its value.

net: dsa: mv88e6xxx: 2500Base-X uses the 1000Base-X SERDES

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

The 6390 has three different SERDES interface types. 2500Base-X is
implemented by the SGMII/1000Base-X SERDES. So power on/off the
correct SERDES.
