2015-08-11Revert "Merge branch 'mv88e6xxx-switchdev-fdb'"David S. Miller
This reverts commit f1d5ca434413b20cd3f8c18ff2b634b7782149a5, reversing changes made to 4933d85c5173832ebd261756522095837583c458. I applied v2 instead of v3. Signed-off-by: David S. Miller <davem@davemloft.net>

2015-08-09net: dsa: mv88e6xxx: rework FDB getnext operationVivien Didelot
This commit adds a low level _mv88e6xxx_atu_getnext function and helpers to rewrite the mv88e6xxx_port_fdb_getnext operation. A mv88e6xxx_atu_entry structure is added for convenient access to the hardware, and GLOBAL_ATU_FID is defined instead of the raw 0x01 value. The previous implementation did not handle the eventual trunk mapping. If the related bit is set, then the ATU data register would contain the trunk ID, and not the port vector. Check this in the FDB getnext operation and do not handle it (yet). Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-09net: dsa: mv88e6xxx: extend fid maskVivien Didelot
The driver currently manages one FID per port (or bridge group), with a mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use. The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff; FID 0 means that multiple address databases are not being used). This patch changes the fid_mask for an fid_bitmap of 4096 bits. >From now on, FIDs 1 to num_ports are reserved for non-bridged ports and bridge groups (a bridge group gets the FID of its first member). The remaining bits will be reserved for VLAN entries. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-07-27dsa: mv88e6352/mv88e6xxx: Move temperature sensor code to mv88e6xxx.cGuenter Roeck
Move the temperature sensing code for mv88e6352 and mv88e6320 families into mv88e6xxx.c to simplify adding support for additional chips. With this change, mv88e6xxx_6320_family() no longer needs to be a global function and is made static.

2015-05-09net: dsa: mv88e6xxx: Replace PHY mutex by SMI mutexAndrew Lunn
The SMI bus is the bottleneck in all switch operations, not the granularity of locks. Replace the PHY mutex by the SMI mutex to make the locking concept simpler. The REG_READ/REG_WRITE macros cannot be used while holding the SMI mutex, since they try to acquire it. Replace with calls to the appropriate function which does not try to get the mutex.

2015-05-09net: dsa: Centralise global and port setup code into mv88e6xxx.Andrew Lunn
The port setup code in the individual drivers is identical for 6123, 6171, and 6352, and very similar in 6131. Move it all into mv88e6xxx, using the chip families to differentiate on features. Similarly, the global setup is also very similar. Move the majority into mv8e6xxx. The chips themselves fall into families. Add helpers which uses the device IDs to determine if a device is a member of a family or not. Add some additional device IDs to the existing list, to make these helper functions more complete. However these IDs are not yet added to the probe functions. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-10-30net: dsa/mv88e6352: Implement EEPROM access functionsGuenter Roeck
MV88E6352 supports read and write access to its configuration eeprom. There is no means to detect if an EEPROM is connected to the switch. Also, the switch supports EEPROMs with different sizes, but can not detect or report the type or size of connected EEPROMs. Therefore, do not implement the get_eeprom_len callback but depend on platform or devicetree data to provide information about EEPROM presence and size.
