Merge series "New DSA driver for VSC9953 Seville switch" from Vladimir Oltean <olteanv@gmail.com>:

Looking at the Felix and Ocelot drivers, Maxim asked if it would be
possible to use them as a base for a new driver for the switch inside
NXP T1040. Turns out, it is! The result is a driver eerily similar to
Felix.

The biggest challenge seems to be getting register read/write API
generic enough to cover such wild bitfield variations between hardware
generations. There is a patch on the regmap core which I would like to
get in through the networking subsystem, if possible (and if Mark is
ok), since it's a trivial addition.

Maxim Kochetkov (4):
  soc/mscc: ocelot: add MII registers description
  net: mscc: ocelot: convert SYS_PAUSE_CFG register access to regfield
  net: mscc: ocelot: extend watermark encoding function
  net: dsa: ocelot: introduce driver for Seville VSC9953 switch

Vladimir Oltean (7):
  regmap: add helper for per-port regfield initialization
  net: mscc: ocelot: unexport ocelot_probe_port
  net: mscc: ocelot: convert port registers to regmap
  net: mscc: ocelot: convert QSYS_SWITCH_PORT_MODE and SYS_PORT_MODE to
    regfields
  net: dsa: ocelot: create a template for the DSA tags on xmit
  net: mscc: ocelot: split writes to pause frame enable bit and to
    thresholds
  net: mscc: ocelot: disable flow control on NPI interface
