2016-05-09net: dsa: mv88e6xxx: factorize the switch driverVivien Didelot
Now that all drivers support the same set of functions and the same setup code, drop every model-specific DSA switch driver and replace them with a common mv88e6xxx driver. This merges the info tables into one, removes the function exports, the model-specific files, and update the defconfigs.

Provide a shared mv88e6xxx_setup function to the drivers. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_CONTROL_2 setupVivien Didelot
All switch models setup the GLOBAL_CONTROL_2 register with slightly differences. Since the cascade mode is valid even in a single chip setup, factorize such configuration. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_MONITOR_CONTROL setupVivien Didelot
All switch drivers configure the GLOBAL_MONITOR_CONTROL register with slightly changes. Assume the setup of the upstream port, and configure it as the port to which ingress and egress and ARP monitor frames are to be sent.

2016-05-09net: dsa: mv88e6xxx: factorize GLOBAL_CONTROL setupVivien Didelot
All switch models configure the GLOBAL_CONTROL register with slightly differences. Discarding packets with excessive collisions (GLOBAL_CONTROL_DISCARD_EXCESS) is specific to 6352 and similar switches, and setting a maximum frame size (GLOBAL_CONTROL_MAX_FRAME_1632) is specific to 6185 and similar switches. As we are centralizing the chips setup, skip these settings and don't discard any frames yet, until we found out that such discarding by the hardware is necessary. Assume a common setup to enable the PHY Polling Unit if present, don't discard any packets, and mask all interrupt sources. Tested on 88E6352 and 88E6185.

2016-05-09net: dsa: mv88e6xxx: factorize global setupVivien Didelot

2016-05-09net: dsa: mv88e6xxx: factorize MAC address settingVivien Didelot
Some switch models have a dedicated register for Switch MAC/WoF/WoL. This register, when present, is used to indirectly set the switch MAC address, instead of a direct write to 3 global registers. Identify this feature and share a common mv88e6xxx_set_addr function. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-04-17net: dsa: mv88e6xxx: drop revision probingVivien Didelot
There is no point in having a special case for the revision when probing a switch model. The code gets cluttered with unnecessary defines, and leads to errors when code such as mv88e6131_setup compares PORT_SWITCH_ID_6131_B2 to ps->id which masks the revision. Drop every revision definition, and lookup only the product number.
