* net: dsa: Use mnemonics rather than register numbersAndrew Lunn2015-04-01
| | | | | | | | | | Rather than refer to registers by number, define mnemonics. Also define mnemonics for the commonly used bits within the registers.

* net: dsa: Consolidate getting the statisticsAndrew Lunn2015-04-01
| | | | | | | | | | | Reading the statistics from the hardware is the same for all chips. What differs is the number of available statistics. Have just one copy of the code in the shared mv88e6xxx.

* net: dsa: Centralize Marvell switch resetAndrew Lunn2015-04-01
| | | | | | | | | | | Marvell switches are all reset in nearly the same way. The only difference is if the PPU should be enabled or not. Move this code into the shared mv88x6xxx.c.

* net: dsa: mv88e6352: Refactor shareable codeAndrew Lunn2015-02-19
| | | | | | | | | | | The mv88e6352 allows access to the port phys via an internal mdio bus which is accessed using registers in the GLOBAL 2 range. The mv88e6171 and probably other devices use the same mechanism. Move this code into the shared mv88e6xxx.c library.

* net: dsa/mv88e6352: make mv88e6352_wait genericVivien Didelot2015-01-27
| | | | | | | | | | | | | | Some busy bits are available in the global register 1, such as the ATU Busy bit. We may want to use this function to wait for them to change, so add a new parameter to mv88e6352_wait() instead of hard-coding REG_GLOBAL2. In the meantime, since the REG_READ() macro already checks for error, remove the redundant check for ret < 0.

* net: dsa/mv88e6352: Implement EEPROM access functionsGuenter Roeck2014-10-30
| | | | | | | | | | | | | 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.
