We only register the ATU and VTU irq when we have a chip level IRQ.
In the error path, we should only attempt to remove the ATU and VTU
irq if we also have a chip level IRQ.

Fix a cut/paste error. When irq_find_mapping() returns an error for

devm_gpiod_get_optional() can return an error in addition to a NULL ptr.
Check for error and propagate that to the probe function. Check return
value in probe. This will now handle EPROBE_DEFER for the reset gpio.

Models such as BCM5395/97/98 and BCM53125/24/53115 and compatible require that
we turn on managed mode to actually act on Broadcom tags, otherwise they just
pass them through on ingress (host -> switch) and don't insert them in egress
(switch -> host). Turning on managed mode is simple, but requires us to
properly support ARL misses on multicast addresses which is a much more
involved set of changes not suitable for a bug fix for this release.

MT7530 can treat each port as either VLAN-unaware port or VLAN-aware port
through the implementation of port matrix mode or port security mode on
the ingress port, respectively. On one hand, Each port has been acting as
the VLAN-unaware one whenever the device is created in the initial or
certain port joins or leaves into/from the bridge at the runtime. On the
other hand, the patch just filling the required callbacks for VLAN
operations is achieved via extending the port to be into port security
mode when the port is configured as VLAN-aware port. Which mode can make
the port be able to recognize VID from incoming packets and look up VLAN
table to validate and judge which port it should be going to. And the
range for VID from 1 to 4094 is valid for the hardware.

XGMII is a 32-bit bus plus two clock signals per direction. XAUI is
four serial lanes per direction. The 88e6190 supports XAUI but not
XGMII as it doesn't have enough pins. The same is true of 88e6176.
Match on PHY_INTERFACE_MODE_XAUI for the XAUI port type, but keep
accepting XGMII for backwards compatibility.

The MDIO busses need to be unregistered before they are freed,
otherwise BUG() is called. Add a call to the unregister code if the
registration fails, since we can have multiple busses, of which some
may correctly register before one fails. This requires moving the code

When removing the interrupt handling code, we should mask the
generation of interrupts. The code however unmasked all
interrupts. This can then cause a new interrupt. We then get into a
deadlock where the interrupt thread is waiting to run, and the code
continues, trying to remove the interrupt handler, which means waiting
for the thread to complete. On a UP machine this deadlocks.
Fix so we really mask interrupts in the hardware. The same error is
made in the error path when install the interrupt handling code.

The current dsa_upstream_port() helper still assumes a unique CPU port
in the whole switch fabric. This is becoming wrong, as every port in the
fabric has its dedicated CPU port, thus every port has an upstream port.
Add a port argument to the dsa_upstream_port() helper and fetch its CPU
port instead of the deprecated unique fabric CPU port. A CPU or unused
port has no dedicated CPU port, so return itself in this case.
At the same time, change the return value from u8 to unsigned int since
there is no need to limit the size here.

The mv88e6xxx driver currently assumes a single CPU port in the fabric
and thus floods frames with unknown DA on a single DSA port, the one
that is one hop closer to the CPU port.
With multiple CPU ports in mind, this isn't true anymore because CPU
ports could be found behind both DSA ports of a device in-between
others.
For example in a A <-> B <-> C fabric, both A and C having CPU ports,
device B will have to flood such frame to its two DSA ports.
This patch considers both CPU and DSA ports of a device as upstream
ports, where to flood frames with unknown DA addresses.

This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.
Casting from unsigned long:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
setup_timer(&ptr->my_timer, my_callback, ptr);
and forced object casts:
void my_callback(struct something *ptr)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);
become:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
Direct function assignments:
void my_callback(unsigned long data)
{
struct something *ptr = (struct something *)data;
...
}
...
ptr->my_timer.function = my_callback;
have a temporary cast added, along with converting the args:
void my_callback(struct timer_list *t)
{
struct something *ptr = from_timer(ptr, t, my_timer);
...
}
...
ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;
And finally, callbacks without a data assignment:
void my_callback(unsigned long data)
{
...
}
...
setup_timer(&ptr->my_timer, my_callback, 0);
have their argument renamed to verify they're unused during conversion:
void my_callback(struct timer_list *unused)
{
...
}
...
timer_setup(&ptr->my_timer, my_callback, 0);
The conversion is done with the following Coccinelle script:
spatch --very-quiet --all-includes --include-headers \
-I ./arch/x86/include -I ./arch/x86/include/generated \
-I ./include -I ./arch/x86/include/uapi \

On BCM58xx devices (Northstar Plus), there is an accelerator attached to
port 8 which would only work if we use prepended Broadcom tags. Resolve
that difference in our get_tag_protocol() function by setting the
appropriate tagging protocol in that case. We need to change
b53_brcm_hdr_setup() a little bit now since we can deal with two types
of Broadcom tags.

Enable Broadcom tags for b53 devices, except 5325 and 5365 which use a
different Broadcom tag format not yet supported by net/dsa/tag_brcm.c.
We also make sure that we can turn on Broadcom tags on a CPU port number
that is capable of that: 5, 7 or 8.

dev->cpu_port is the driver local information that should only be used
to look up register offsets for a particular port, when they differ
(e.g: IMP port override), but it should certainly not be used in place
of the DSA configured CPU port.
Since the DSA switch layer calls port_vlan_{add,del}() on the CPU port
as well, we can remove the specific setting of the CPU port within
port_vlan_{add,del}.

IGMP packets should be trapped to the CPU port. The SW bridge knows
whether to forward to other ports.
With "IGMP snooping for local traffic" merged, IGMP trapping is also
required for stable IGMPv2 operation.
LAN9303 does not trap IGMP packets by default.
Enable IGMP trapping in lan9303_setup.

The statistics histogram mode was not being explicitly initialized on
devices other than the 6390 family. Clearing the statistics then
overwrote the default setting, setting the histogram to a reserved
mode.
Explicitly set the histogram mode for all devices. Change the
statistics clear into a read/modify/write, and since it is now more
complex, move it into global1.c.

By default, the switch does not flood broadcast frames. Instead the
broadcast address is unknown in the ATU, so the frame gets forwarded
out the cpu port. The software bridge then floods it back to the
individual switch ports which are members of the bridge.
Add an ATU entry in the switch so that it floods broadcast frames out
ports, rather than have the software bridge do it. Also, send a copy
out the cpu port and any dsa ports. Rely on the port vectors to
prevent broadcast frames leaking between bridges, and separated ports.
Additionally, when a VLAN is added, a new FID is allocated. This
represents a new table of ATU entries. A broadcast entry is added to
the new FID.
With offload_fwd_mark being set, the software bridge will not flood
the frames it receives back to the switch.

Having the same VLAN on multiple bridges is currently unsupported as
an offload. mv88e6xxx_port_check_hw_vlan() is used to ensure that a
VLAN is not on multiple bridges when adding a VLAN range to a port. It
loops the ports and checks to see if there are ports in a different
bridge with the same VLAN.
While walking all switch ports, the code was checking if the new port
has a netdev slave attached to it. If not, skip checking the port
being walked. This seems like a typ0. If the new port does not have a
slave, how has a VLAN been added to it in the first place, requiring
this check be performed at all? More likely, we should be checking if
the port being walked has a slave. Without the port having a slave, it
cannot have a VLAN on it, so there is no need to check further for
that particular port.
