Subject: [PATCH RFC v2 00/32] Make DSA switches linux devices.

This is the second RFC for rearchitecturing how DSA devices are
probed. This patchset allows switches to be linux devices, probed by
the ususal mechanism for whatever bus they hang off. They then
register with the DSA core.

DSA has been limited to devices which hang off an MDIO bus, or with a
bit of work, memory mapped devices. This refactoring generalizes DSA
so that switches on other sorts of busses, eg. SPI can be supported.

The code should remain backwards compatible. The old device tree
binding are still supported. It is extended with phandles to switch
devices.

The changes also make it eaiser for the drivers to be kernel modules,
and the patches contain cleanups and fixes so that the modules can be
unloaded and loaded.

Patches can be found in

Andrew Lunn (30):
  dsa: Rename mv88e6123_61_65 to mv88e6123 to be consistent
  dsa: Make setup and finish more symmetrical
  net: dsa: Pass the dsa device to the switch drivers
  net: dsa: Have the switch driver allocate there own private memory
  net: dsa: Remove allocation of driver private memory
  net: dsa: Keep the mii bus and address in the private structure
  net: dsa: dsa.c: Refactor to increase symmetry
  driver: component: Add support for empty match table
  net: dsa: Add basic support for component master support
