Merge branch 'dsa-next' 

Andrew Lunn says:

====================
More Marvell DSA refactring and fixup

This patch setup continues the refactoring and cleanup of the Marvell
DSA drivers.

Patch #1 Centralizes the duplicated parts of port setup and global
setup into the shared mv88e6xxx.

Patch #2 Centralizes looping over the ports setting them up

Patch #3 Uses mnemonics for the remaining register access in the
drivers.

Patch #4 The 6172 is actually a member of the 6352 family. This moves
the probe code into the correct driver.

Patch #5 Adds more members of the 6171 family to the 6171 driver. The
new devices are untested.

Patch #6 The 6185 is a member of the 6131 family. Add it to the probe
code of the 6131 driver.

Patch #7 and Patch #8 Simply the mutex's in mv88e6xxx.c. The SMI bus
is the bottleneck, not the granularity of the mutex's so simply the
code down to a single mutex.

Patch #8 Fixes a false positive lockdep splat, due to nested uses of
MDIO busses.

Patch #9 Fixes another false positive lockdep splat with the transmit
queue because of stacked Ethernet devices.
