Later with TCP-AO option added, this will allow to create one function
that's responsible for segment verification, that will have all the
different checks for MD5/AO/non-signed packets, which in turn will help
to see checks for all corner-cases in one function, rather than spread

FDB entries on DSA LAG interfaces
This work permits having static and local FDB entries on LAG interfaces
that are offloaded by DSA ports. New API needs to be introduced in
drivers. To maintain consistency with the bridging offload code, I've
taken the liberty to reorganize the data structures added by Tobias in
the DSA core a little bit.
Tested on NXP LS1028A (felix switch). Would appreciate feedback/testing
on other platforms too. Testing procedure was the one described here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210205130240.4072854-1-vladimir.oltean@nxp.com/
with this script:
ip link del bond0
ip link add bond0 type bond mode 802.3ad
ip link set swp1 down && ip link set swp1 master bond0 && ip link set swp1 up
ip link set swp2 down && ip link set swp2 master bond0 && ip link set swp2 up
ip link del br0
ip link add br0 type bridge && ip link set br0 up
ip link set br0 arp off
ip link set bond0 master br0 && ip link set bond0 up
ip link set swp0 master br0 && ip link set swp0 up
ip link set dev bond0 type bridge_slave flood off learning off
bridge fdb add dev bond0 <mac address of other eno0> master static
I'm noticing a problem in 'bridge fdb dump' with the 'self' entries, and
I didn't solve this. On Ocelot, an entry learned on a LAG is reported as
being on the first member port of it (so instead of saying 'self bond0',
it says 'self swp1'). This is better than not seeing the entry at all,
but when DSA queries for the FDBs on a port via ds->ops->port_fdb_dump,
it never queries for FDBs on a LAG. Not clear what we should do there,
we aren't in control of the ->ndo_fdb_dump of the bonding/team drivers.
Alternatively, we could just consider the 'self' entries reported via
ndo_fdb_dump as "better than nothing", and concentrate on the 'master'
entries that are in sync with the bridge when packets are flooded to
software.

This adds the logic in the Felix DSA driver and Ocelot switch library.
For Ocelot switches, the DEST_IDX that is the output of the MAC table
lookup is a logical port (equal to physical port, if no LAG is used, or
a dynamically allocated number otherwise). The allocation we have in
place for LAG IDs is different from DSA's, so we can't use that:
- DSA allocates a continuous range of LAG IDs starting from 1
- Ocelot appears to require that physical ports and LAG IDs are in the
same space of [0, num_phys_ports), and additionally, ports that aren't
in a LAG must have physical port id == logical port id
The implication is that an FDB entry towards a LAG might need to be
deleted and reinstalled when the LAG ID changes.

This change introduces support for installing static FDB entries towards
a bridge port that is a LAG of multiple DSA switch ports, as well as
support for filtering towards the CPU local FDB entries emitted for LAG
interfaces that are bridge ports.
Conceptually, host addresses on LAG ports are identical to what we do
for plain bridge ports. Whereas FDB entries _towards_ a LAG can't simply
be replicated towards all member ports like we do for multicast, or VLAN.
Instead we need new driver API. Hardware usually considers a LAG to be a
"logical port", and sets the entire LAG as the forwarding destination.
The physical egress port selection within the LAG is made by hashing
policy, as usual.
To represent the logical port corresponding to the LAG, we pass by value
a copy of the dsa_lag structure to all switches in the tree that have at
least one port in that LAG.
To illustrate why a refcounted list of FDB entries is needed in struct
dsa_lag, it is enough to say that:
- a LAG may be a bridge port and may therefore receive FDB events even
while it isn't yet offloaded by any DSA interface
- DSA interfaces may be removed from a LAG while that is a bridge port;
we don't want FDB entries lingering around, but we don't want to
remove entries that are still in use, either
For all the cases below to work, the idea is to always keep an FDB entry
on a LAG with a reference count equal to the DSA member ports. So:
- if a port joins a LAG, it requests the bridge to replay the FDB, and
the FDB entries get created, or their refcount gets bumped by one
- if a port leaves a LAG, the FDB replay deletes or decrements refcount
by one
- if an FDB is installed towards a LAG with ports already present, that
entry is created (if it doesn't exist) and its refcount is bumped by
the amount of ports already present in the LAG

By construction, the struct net_device *dev passed to

is always a DSA slave device.
Therefore, it is redundant to pass struct dsa_switch and int port
information in the deferred work structure. This can be retrieved at all
times from the provided struct net_device via dsa_slave_to_port().
For the same reason, we can drop the dsa_is_user_port() check in

When the switchdev_handle_fdb_event_to_device() event replication helper
was created, my original thought was that FDB events on LAG interfaces
should most likely be special-cased, not just replicated towards all
switchdev ports beneath that LAG. So this replication helper currently
does not recurse through switchdev lower interfaces of LAG bridge ports,
but rather calls the lag_mod_cb() if that was provided.
No switchdev driver uses this helper for FDB events on LAG interfaces
yet, so that was an assumption which was yet to be tested. It is
certainly usable for that purpose, as my RFC series shows:
https://patchwork.kernel.org/project/netdevbpf/cover/20220210125201.2859463-1-vladimir.oltean@nxp.com/
however this approach is slightly convoluted because:
- the switchdev driver gets a "dev" that isn't its own net device, but
rather the LAG net device. It must call switchdev_lower_dev_find(dev)
in order to get a handle of any of its own net devices (the ones that
pass check_cb).
- in order for FDB entries on LAG ports to be correctly refcounted per
the number of switchdev ports beneath that LAG, we haven't escaped the
need to iterate through the LAG's lower interfaces. Except that is now
the responsibility of the switchdev driver, because the replication
helper just stopped half-way.
So, even though yes, FDB events on LAG bridge ports must be
special-cased, in the end it's simpler to let switchdev_handle_fdb_*
just iterate through the LAG port's switchdev lowers, and let the
switchdev driver figure out that those physical ports are under a LAG.
The switchdev_handle_fdb_event_to_device() helper takes a
"foreign_dev_check" callback so it can figure out whether @dev can
autonomously forward to @foreign_dev. DSA fills this method properly:
if the LAG is offloaded by another port in the same tree as @dev, then
it isn't foreign. If it is a software LAG, it is foreign - forwarding
happens in software.
Whether an interface is foreign or not decides whether the replication
helper will go through the LAG's switchdev lowers or not. Since the
lan966x doesn't properly fill this out, FDB events on software LAG
uppers will get called. By changing lan966x_foreign_dev_check(), we can
suppress them.
Whereas DSA will now start receiving FDB events for its offloaded LAG
uppers, so we need to return -EOPNOTSUPP, since we currently don't do
the right thing for them.

The main purpose of this change is to create a data structure for a LAG
as seen by DSA. This is similar to what we have for bridging - we pass a
copy of this structure by value to ->port_lag_join and ->port_lag_leave.
For now we keep the lag_dev, id and a reference count in it. Future
patches will add a list of FDB entries for the LAG (these also need to
be refcounted to work properly).
The LAG structure is created using dsa_port_lag_create() and destroyed
using dsa_port_lag_destroy(), just like we have for bridging.
Because now, the dsa_lag itself is refcounted, we can simplify
dsa_lag_map() and dsa_lag_unmap(). These functions need to keep a LAG in
the dst->lags array only as long as at least one port uses it. The
refcounting logic inside those functions can be removed now - they are
called only when we should perform the operation.
dsa_lag_dev() is renamed to dsa_lag_by_id() and now returns the dsa_lag
structure instead of the lag_dev net_device.
dsa_lag_foreach_port() now takes the dsa_lag structure as argument.
dst->lags holds an array of dsa_lag structures.
dsa_lag_map() now also saves the dsa_lag->id value, so that linear
walking of dst->lags in drivers using dsa_lag_id() is no longer
necessary. They can just look at lag.id.
dsa_port_lag_id_get() is a helper, similar to dsa_port_bridge_num_get(),
which can be used by drivers to get the LAG ID assigned by DSA to a
given port.

The DSA LAG API will be changed to become more similar with the bridge
data structures, where struct dsa_bridge holds an unsigned int num,
which is generated by DSA and is one-based. We have a similar thing
going with the DSA LAG, except that isn't stored anywhere, it is
calculated dynamically by dsa_lag_id() by iterating through dst->lags.
The idea of encoding an invalid (or not requested) LAG ID as zero for
the purpose of simplifying checks in drivers means that the LAG IDs
passed by DSA to drivers need to be one-based too. So back-and-forth
conversion is needed when indexing the dst->lags array, as well as in
drivers which assume a zero-based index.

If one of our PHYs fails to complete calibration, we should skip the
general initialization of the corresponding output. Most likely this is
going to happen on outputs that don't actually exist on the board; in
theory we should have already decided to skip this output based on the
VBT, but we can't always rely on the VBT being accurate.

TE-gpio, if defined, is placed in the panel's node, not the parent DSI
node. Change the devm_gpiod_get_optional() to gpiod_get_optional() and
pass proper device node to it. The code already has a proper cleanup
path, so it looks that the devm_* variant has been applied accidentally
during the conversion to gpiod API.

Fixed a typo.

TE-gpio is optional and if it is not found then gpiod_get_optional()
returns NULL. In such case the code will continue and try to convert NULL
gpiod to irq what in turn fails. The failure is then propagated and driver
is not registered.
Fix this by returning early from exynos_dsi_register_te_irq() if no
TE-gpio is found.

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypassed the hierarchical setup and messed up the
irq chaining.

Currently, the amber LED will remain always on. This is due to a
misinterpretation of the LED sub-node properties, where-by "default-state"
was used to indicate the initial state when powering on the device. When in
use, however, this resulted in the amber LED always being on. Instead change
this to only indicate a fault state.
Assign LED_FUNCTION_POWER to the green PWM LED.
These changes bring the MX64/65 in line with the MR32's devicetree.

On SC7180 we observe black screens because the gdsc is being
enabled/disabled very rapidly and the GDSC FSM state does not work as
expected. This is due to the fact that the GDSC reset value is being
updated from SW.

GDSCs have multiple transition delays which are used for the GDSC FSM
states. Older targets/designs required these values to be updated from
gdsc code to certain default values for the FSM state to work as
expected. But on the newer targets/designs the values updated from the
GDSC driver can hamper the FSM state to not work as expected.
On SC7180 we observe black screens because the gdsc is being
enabled/disabled very rapidly and the GDSC FSM state does not work as
expected. This is due to the fact that the GDSC reset value is being
updated from SW.
Thus add support to update the transition delay from the clock
controller gdscs as required.
