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.
