* 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.

| | | | | | | | | | | 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.

| | | | | | | | | | | 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: mv88e6171: Enable access to phys via internal mdio busAndrew Lunn2015-02-19
| | | | | | | | | | When the device is configured to use single chip addressing mode, the phy devices of the port are not accessible on the host MDIO bus. Instead the switch internal MDIO bus must be used. For this to work, the phy polling unit must be enabled. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

* dsa: mv88e6171: Fix tagging protocol/KconfigAndrew Lunn2014-10-28
| | | | | | | | | | | | | | | | | The mv88e6171 can support two different tagging protocols, DSA and EDSA. The switch driver structure only allows one protocol to be enumerated, and DSA was chosen. However the Kconfig entry ensures the EDSA tagging code is built. With a minimal configuration, we then end up with a mismatch. The probe is successful, EDSA tagging is used, but the switch is configured for DSA, resulting in mangled packets. Change the switch driver structure to enumerate EDSA, fixing the mismatch.

* dsa: Replace mii_bus with a generic host deviceAlexander Duyck2014-09-15
| | | | | | | | | | | | | This change makes it so that instead of passing and storing a mii_bus we instead pass and store a host_dev. From there we can test to determine the exact type of device, and can verify it is the correct device for our switch. So for example it would be possible to pass a device pointer from a pci_dev and instead of checking for a PHY ID we could check for a vendor and/or device ID.
