Vladimir Oltean says:

====================
Felix DSA driver cleanup: build Seville separately

When introducing the Seville switch support to the Felix driver, some
technical debt was created. Since both VSC9959 and VSC9953 are embedded
switches (one on an arm64 SoC and the other on a powerpc SoC), there is
no use case for having the code for both be present in the same module.

This was necessary at the time due to the common SERDES PCS code that
they were using, but that has been since refactored into
drivers/net/pcs/pcs-lynx.c.

This makes the Seville driver stop uselessly depending upon PCI and
FSL_ENETC_MDIO, which were only dependencies of Felix in fact.

Some whitespace/tab conversions are also present in this series as part
of the cleanup process.

David S. Miller 5e43df14d6 Merge branch 'net-ipa-wake-up-system-on-RX-available'
Alex Elder says:

====================
net: ipa: wake up system on RX available

This series arranges for the IPA driver to wake up a suspended
system if the IPA hardware has a packet to deliver to the AP.

Version 2 replaced the first patch from version 1 with three
patches, in response to David Miller's feedback.  And based on
Bjorn Andersson's feedback on version 2, this version reworks
the tracking of IPA clock references.  As a result, we no
longer need a flag to determine whether a "don't' suspend" clock
reference is held (though an bit in a bitmask is still used for
a different purpose).

In summary:
    - A refcount_t is used to track IPA clock references where an
      atomic_t was previously used.  (This may go away soon as well,
      with upcoming work to implement runtime PM.)
    - We no longer track whether a special reference has been taken
      to avoid suspending IPA.
    - A bit in a bitmask is used to ensure we only trigger a system
      resume once per system suspend.
And from the original series:
    - Suspending endpoints only occurs when suspending the driver,
      not when dropping the last clock reference.  Resuming
      endpoints is also disconnected from starting the clock.
    - The IPA SUSPEND interrupt is now a wakeup interrupt.  If it
      fires, it schedules a system resume operation.
    - The GSI interrupt is no longer a wakeup interrupt.

Alex Elder 3c6ccdde0f net: ipa: repurpose CLOCK_HELD flag
The previous patch causes a system resume to be triggered when a
packet is available for receipt on a suspended RX endpoint.

The CLOCK_HELD flag was previously used to indicate that an extra
clock reference was held, preventing suspend.  But we no longer need
such a flag:
  - We take an initial reference in ipa_config().
  - That reference is held until ipa_suspend() releases it.
  - A subsequent system resume leads to a reference getting
    re-acquired in ipa_resume().
  - This can repeat until ultimately the module is removed, where
    ipa_remove() releases the reference.
We no longer need a special flag to determine whether this extra
reference is held--it is, provided probe has completed successfully
and the driver is not suspended (or removed).

On the other hand, once suspended, it's possible for more than one
endpoint to trip the IPA SUSPEND interrupt, and we only want to
trigger the system resume once.  So repurpose the Boolean CLOCK_HELD
flag to record whether the IPA SUSPEND handler should initiate a
system resume.

The flag will be be cleared each time ipa_suspend() is called,
*before* any endpoints are suspended.  And it will be set inside the
IPA SUSPEND interrupt handler exactly once per suspend.

Rename the flag IPA_FLAG_RESUMED to reflect its new purpose.

Alex Elder 8529b4b0dc net: ipa: use device_init_wakeup()
The call to wakeup_source_register() in ipa_probe() does not do what
it was intended to do.  Call device_init_wakeup() in ipa_setup()
instead, to set the IPA device as wakeup-capable and to initially
enable wakeup capability.

When we receive a SUSPEND interrupt, call pm_wakeup_dev_event()
with a zero processing time, to simply call for a resume without
any other processing.  The ipa_resume() call will take care of
waking things up again, and will handle receiving the packet.

Note that this gets rid of a clock reference counting bug that
occurred when handling an IPA SUSPEND interrupt.  Specifically,
ipa_suspend_handler() took an IPA clock reference *in addition*
to the one taken by ipa_resume().  There is no need to back-port
this fix however, because it only affects code that was not
previously working (this patch is part of fixing that).

Alex Elder dc6e6072d3 net: ipa: manage endpoints separate from clock
Currently, when (before) the last IPA clock reference is dropped,
all endpoints are suspended.  And whenever the first IPA clock
reference is taken, all endpoints are resumed (or started).

In most cases there's no need to start endpoints when the clock
starts.  So move the calls to ipa_endpoint_suspend() and
ipa_endpoint_resume() out of ipa_clock_put() and ipa_clock_get(),
respectiely.  Instead, only suspend endpoints when handling a system
suspend, and only resume endpoints when handling a system resume.

====================
dpaa2_eth: support 1588 one-step timestamping

This patch-set is to add MC APIs of 1588 one-step timestamping, and
support one-step timestamping for PTP Sync packet on DPAA2.

Before egress, one-step timestamping enablement needs,

- Enabling timestamp and FAS (Frame Annotation Status) in
  dpni buffer layout.

- Write timestamp to frame annotation and set PTP bit in
  FAS to mark as one-step timestamping event.

- Enabling one-step timestamping by dpni_set_single_step_cfg()
  API, with offset provided to insert correction time on frame.
  The offset must respect all MAC headers, VLAN tags and other
  protocol headers accordingly. The correction field update can
  consider delays up to one second. So PTP frame needs to be
  filtered and parsed, and written timestamp into Sync frame
  originTimestamp field.

The operation of API dpni_set_single_step_cfg() has to be done
when no one-step timestamping frames are in flight. So we have
to make sure the last one-step timestamping frame has already
been transmitted on hardware before starting to send the current
one. The resolution is,

- Utilize skb->cb[0] to mark timestamping request per packet.
  If it is one-step timestamping PTP sync packet, queue to skb queue.
  If not, transmit immediately.

- Schedule a work to transmit skbs in skb queue.

- mutex lock is used to ensure the last one-step timestamping packet
  has already been transmitted on hardware through TX confirmation queue
  before transmitting current packet.

Changes for v2:
	- Removed unused variable priv in dpaa2_eth_xdp_create_fd().
Changes for v3:
	- Fixed sparse warnings.
	- Fix build issue on 32-bit.
	- Converted to use ptp_parse_header.
Changes for v4:
	- Used WARN_ONCE instead of netdev_err in data path.
	- Enabled timestamping only when PTP driver is ready.

  has already been transmitted on hardware through TX confirmation queue
  before transmitting current packet.

Yangbo Lu 1cf773bd5a dpaa2-eth: utilize skb->cb[0] for hardware timestamping
This patch is a preparation for next hardware one-step timestamping
support. For DPAA2, the one step timestamping configuration on
hardware registers has to be done when there is no one-step timestamping
packet in flight. So we will have to use workqueue and skb queue
for such packets transmitting, to make sure waiting the last packet has
already been sent on hardware, and starting to transmit the current one.

So the tx timestamping flag in private data may not reflect the actual
request for the one-step timestamping packets of skb queue. This also
affects skb headroom allocation. Let's use skb->cb[0] to mark the
timestamping request for each skb.

Yangbo Lu 64a965dedc dpaa2-eth: invoke dpaa2_eth_enable_tx_tstamp() once in code
Invoke dpaa2_eth_enable_tx_tstamp() once in code after building FD,
rather than calling it in dpaa2_eth_build_single_fd(),
dpaa2_eth_build_sg_fd_single_buf(), and dpaa2_eth_build_sg_fd().

Yangbo Lu d21c784c78 dpaa2-eth: define a global ptp_qoriq structure pointer
Define a global ptp_qoriq structure pointer, and export to use.
The ptp clock operations will be used in dpaa2-eth driver.
For example, supporting one step timestamping needs to write
current time to hardware frame annotation before sending and
then hardware inserts the delay time on frame during sending.
So in driver, at least clock gettime operation will be needed
to make sure right time is written to hardware frame annotation
for one step timestamping.

Mahesh Bandewar 3753d97790 net: fix build without CONFIG_SYSCTL definition
Earlier commit 316cdaa115 ("net: add option to not create fall-back
tunnels in root-ns as well") removed the CONFIG_SYSCTL to enable the
kernel-commandline to work. However, this variable gets defined only
when CONFIG_SYSCTL option is selected.

With this change the behavior would default to creating fall-back
tunnels in all namespaces when CONFIG_SYSCTL is not selected and
the kernel commandline option will be ignored.
