net: dsa: sja1105: add support for the SJA1110 switch family
The SJA1110 is basically an SJA1105 with more ports, some integrated
PHYs (100base-T1 and 100base-TX) and an embedded microcontroller which
can be disabled, and the switch core can be controlled by a host running
Linux, over SPI.
This patch contains:
- the static and dynamic config packing functions, for the tables that
are common with SJA1105
- one more static config tables which is "unique" to the SJA1110
(actually it is a rehash of stuff that was placed somewhere else in
SJA1105): the PCP Remapping Table
- a reset and clock configuration procedure for the SJA1110 switch.
This resets just the switch subsystem, and gates off the clock which
powers on the embedded microcontroller.
- an RGMII delay configuration procedure for SJA1110, which is very
similar to SJA1105, but different enough for us to be unable to reuse
it (this is a pattern that repeats itself)
- some adaptations to dynamic config table entries which are no longer
programmed in the same way. For example, to delete a VLAN, you used to
write an entry through the dynamic reconfiguration interface with the
desired VLAN ID, and with the VALIDENT bit set to false. Now, the VLAN
table entries contain a TYPE_ENTRY field, which must be set to zero
(in a backwards-incompatible way) in order for the entry to be deleted,
or to some other entry for the VLAN to match "inner tagged" or "outer
tagged" packets.
- a similar thing for the static config: the xMII Mode Parameters Table
encoding for SGMII and MII (the latter just when attached to a
100base-TX PHY) just isn't what it used to be in SJA1105. They are
identical, except there is an extra "special" bit which needs to be
set. Set it.
