PTP TX port timestamp relies on receiving 2 CQEs for each outgoing
packet (WQE). The regular CQE has a less accurate timestamp than the
wire CQE. On link change, the wire CQE may get lost. Let the driver
detect and restore the relation between the CQEs, and re-sync after
timeout.
Add resiliency for this as follows: add id (producer counter)
into the WQE's metadata. This id will be received in the wire
CQE (in wqe_counter field). On handling the wire CQE, if there is no
match, replay the PTP application with the time-stamp from the regular
CQE and restore the sync between the CQEs and their SKBs. This patch
adds 2 ptp counters:
1) ptp_cq0_resync_event: number of times a mismatch was detected between
the regular CQE and the wire CQE.
2) ptp_cq0_resync_cqe: total amount of missing wire CQEs.

Add support for RZ/N1 SJA1000 CAN controller
This patch series aims to add support for RZ/N1 SJA1000 CAN controller.
The SJA1000 CAN controller on RZ/N1 SoC has some differences compared
to others like it has no clock divider register (CDR) support and it has
no HW loopback (HW doesn't see tx messages on rx), so introduced a new
compatible 'renesas,rzn1-sja1000' to handle these differences.
v3->v4:
* Updated bindings as per coding style used in example-schema.
* Entire entry in properties compatible declared as enum. Also Descriptions
do not bring any information,so removed it from compatible description.
* Used decimal values in nxp,tx-output-mode enums.
* Fixed indentaions in binding examples.
* Removed clock-names from bindings, as it is single clock.
* Optimized the code as per Vincent's suggestion.
* Updated clock handling as per bindings.
v2->v3:
* Added reg-io-width is a required property for technologic,sja1000 & renesas,rzn1-sja1000
* Removed enum type from nxp,tx-output-config and updated the description
for combination of TX0 and TX1.
* Updated the example for technologic,sja1000
v1->v2:
* Moved $ref: can-controller.yaml# to top along with if conditional to
avoid multiple mapping issues with the if conditional in the subsequent
patch.
* Added an example for RZ/N1D SJA1000 usage.
* Updated commit description for patch#2,#3 and #6
* Removed the quirk macro SJA1000_NO_HW_LOOPBACK_QUIRK
* Added prefix SJA1000_QUIRK_* for quirk macro.
* Replaced of_device_get_match_data->device_get_match_data.
* Added error handling on clk error path
* Started using "devm_clk_get_optional_enabled" for clk get,prepare and enable.

amt: fix validation and synchronization bugs
There are some synchronization issues in the amt module.
Especially, an amt gateway doesn't well synchronize its own variables
and status(amt->status).
It tries to use a workqueue for handles in a single thread.
A global lock is also good, but it would occur complex locking complex.
In this patchset, only the gateway uses workqueue.
The reason why only gateway interface uses workqueue is that gateway
should manage its own states and variables a little bit statefully.
But relay doesn't need to manage tunnels statefully, stateless is okay.
So, relay side message handlers are okay to be called concurrently.
But it doesn't mean that no lock is needed.
Only amt multicast data message type will not be processed by the work
queue because It contains actual multicast data.
So, it should be processed immediately.
When any amt gateway events are triggered(sending discovery message by
delayed_work, sending request message by delayed_work and receiving
messages), it stores event and skb into the event queue(amt->events[16]).
Then, workqueue processes these events one by one.
The first patch is to use the work queue.
The second patch is to remove unnecessary lock due to a previous patch.
The third patch is to use READ_ONCE() in the amt module.
Even if the amt module uses a single thread, some variables (ready4,
ready6, amt->status) can be accessed concurrently.
The fourth patch is to add missing nonce generation logic when it sends a
new request message.
The fifth patch is to drop unexpected advertisement messages.
advertisement message should be received only after the gateway sends
a discovery message first.
So, the gateway should drop advertisement messages if it has never
sent a discovery message and it also should drop duplicate advertisement
messages.
Using nonce is good to distinguish whether a received message is an
expected message or not.
The sixth patch is to drop unexpected query messages.
This is the same behavior as the fourth patch.
Query messages should be received only after the gateway sends a request
message first.
The nonce variable is used to distinguish whether it is a reply to a
previous request message or not.
amt->ready4 and amt->ready6 are used to distinguish duplicate messages.
The seventh patch is to drop unexpected multicast data.
AMT gateway should not receive multicast data message type before
establish between gateway and relay.
In order to drop unexpected multicast data messages, it checks amt->status.
The last patch is to fix a locking problem on the relay side.
amt->nr_tunnels variable is protected by amt->lock.
But amt_request_handler() doesn't protect this variable.
v2:
- Use local_bh_disable() instead of rcu_read_lock_bh() in
amt_membership_query_handler.
- Fix using uninitialized variables.
- Fix unexpectedly start the event_wq after stopping.
- Fix possible deadlock in amt_event_work().
- Add a limit variable in amt_event_work() to prevent infinite working.
- Rename amt_queue_events() to amt_queue_event().

There are some synchronization issues(amt->status, amt->req_cnt, etc)
if the interface is in gateway mode because gateway message handlers
are processed concurrently.
This applies a work queue for processing these messages instead of
expanding the locking context.
So, the purposes of this patch are to fix exist race conditions and to make
gateway to be able to validate a gateway status more correctly.
When the AMT gateway interface is created, it tries to establish to relay.
The establishment step looks stateless, but it should be managed well.
In order to handle messages in the gateway, it saves the current
status(i.e. AMT_STATUS_XXX).
This patch makes gateway code to be worked with a single thread.
Now, all messages except the multicast are triggered(received or
delay expired), and these messages will be stored in the event
queue(amt->events).
Then, the single worker processes stored messages asynchronously one
by one.
The multicast data message type will be still processed immediately.
Now, amt->lock is only needed to access the event queue(amt->events)
if an interface is the gateway mode.
