Subject: [PATCH v3 net-next 0/9] mv88e6xxx: Add devlink regions support

Make use of devlink regions to allow read access to some of the
internal of the switches. Currently access to global1, global2 and the
ATU is provided.

The switch itself will never trigger a region snapshot, it is assumed
it is performed from user space as needed.

v2:
Remove left of debug print
Comment ATU format is generic to mv88e6xxx
Combine declaration and the assignment on a single line.

v3:
Drop support for port regions
Improve the devlink API with a priv member and passing the region to
the snapshot function
Make the helper to convert from devlink to ds an inline function

Andrew Lunn (9):
  net: devlink: regions: Add a priv member to the regions ops struct
  net: devlink: region: Pass the region ops to the snapshot function
  net: dsa: Add helper to convert from devlink to ds

  net: dsa: mv88e6xxx: Add devlink regions
  net: dsa: wire up devlink info get
