ed3af5fd08 net: dsa: b53: Add support for port mirroring
Add support for configuring port mirroring through the cls_matchall
classifier. We do a full ingress or egress capture towards the capture
port. Future improvements could include leveraging the divider to allow
less frames to be captured, as well as matching specific MAC DA/SA.

ddd3a0c840 net: dsa: b53: use dsa_port's bridge pointer
Now that DSA exposes the bridge device pointer to which a port belongs,
use it when programming the port based VLANs and thus remove the cache.

f123f2fbed net: dsa: pass bridge device when a port leaves
Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already
unbridged, so reflect this by assigning the port's bridge_dev pointer to
NULL before calling the port_bridge_leave DSA driver operation.

Now that the bridge_dev pointer is exposed to the drivers, reflecting
the current state of the DSA switch fabric is necessary for the drivers
to adjust their port based VLANs correctly.

Pass the bridge device pointer to the port_bridge_leave operation so
that drivers have all information to re-program their chips properly,
and do not need to cache it anymore.

0fe9933804 net: dsa: bcm_sf2: Add support for BCM7278 integrated switch
Add support for the integrated switch found on BCM7278:

- core_reg_align is set to 1, to force a translation into the target
  address space which is 8 bytes aligned
- an alternate SWITCH_REG layout is provided since registers are largely
  bit/masks compatible but have different offsets
- conditional for all CORE_STS_OVERRIDE_{IMP,GMII_P} since those got
  moved way out of the traditional register space

and introduce a helper function: is58xx() which checks for both of these
IDs for now.

Allocate a device entry for the Broadcom BCM7445 integrated switch
currently backed by bcm_sf2.c. Since this is the latest generation, it
has 4 ARL entries, 4K VLANs and uses Port 8 for the CPU/IMP port.

a2482d2ce3 net: dsa: b53: Plug in VLAN support
Add support for configuration VLANs on B53 devices by implementing the
port VLAN add/del/dump functions. We currently default to a behavior
which is equivalent to having VLAN filtering turned on, where all VLANs
not programmed into the VLAN port-based vector will be discarded on
ingress.

ff39c2d686 net: dsa: b53: Add bridge support
Add support for HW bridging by tying the ports together in the same port
VLAN mask when they belong to the same bridge, and isolating them to be
alone with the CPU port when they are not.

Propagate STP states from the bridge layer to the switch's HW mapping
when requested.

Adds support for FDB add/delete/dump using the ARL read/write logic and
the ARL search logic for faster dumps. The code is made flexible enough
it could support devices with a different register layout like BCM5325
and BCM5365 which have fewer number of entries or pack values into a
single 64 bits register.

967dd82ffc net: dsa: b53: Add support for Broadcom RoboSwitch
This patch adds support for Broadcom's BCM53xx switch family, also known
as RoboSwitch. Some of these switches are ubiquituous, found in home
routers, Wi-Fi routers, DSL and cable modem gateways and other
networking related products.

This drivers adds the library driver (b53_common.c) as well as a few bus
glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and
memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx).

Basic operations are supported to bring the Layer 1/2 up and running,
but not much more at this point, subsequent patches add the remaining
features.
