      Make it explicit that either device tree is used or platform data.  If
neither is available, abort the probe.

      net: ti: cpsw: include gpio/consumer.h · e2b3e493
      Arnd Bergmann authored 
      On platforms that don't always enable CONFIG_GPIOLIB, we run into
a build failure:

drivers/net/ethernet/ti/cpsw.c: In function 'cpsw_probe':
drivers/net/ethernet/ti/cpsw.c:3006:9: error: implicit declaration of function 'devm_gpiod_get_array_optional' [-Werror=implicit-function-declaration]
  mode = devm_gpiod_get_array_optional(&pdev->dev, "mode", GPIOD_OUT_LOW);
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/ti/cpsw.c:3006:59: error: 'GPIOD_OUT_LOW' undeclared (first use in this function); did you mean 'GPIOF_INIT_LOW'?
  mode = devm_gpiod_get_array_optional(&pdev->dev, "mode", GPIOD_OUT_LOW);

Since we cannot rely on this to be visible from gpio.h, we have to include
gpio/consumer.h directly.

      Saeed Mahameed says:

====================
Mellanox, mlx5 new device events

The following series is for mlx5-next tree [1], it adds the support of two
new device events, from Ilan Tayari:

1. High temperature warnings.
2. FPGA QP error event.

In case of no objection this series will be applied to mlx5-next tree
and will be sent later as a pull request to both rdma and net trees.

[1] https://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux.git/log/?h=mlx5-next

v1->v2:
  - improve commit message of the FPGA QP error event patch.

      net/mlx5: Add FPGA QP error event · 1f0cf89b
      Ilan Tayari authored 
      The FPGA queue pair (QP) event fires whenever a QP on the FPGA
transitions to the error state.

At this stage, this event is unrecoverable, it may become recoverable
in the future.

      Temperature warning event is sent by FW to indicate high temperature
as detected by one of the sensors on the board.
Add handling of this event by writing the numbers of the alert sensors
to the kernel log.

      Merge branch 'bridge-vlan-notify' · 9e7c5752
      David S. Miller authored 
      Petr Machata says:

====================
net: bridge: Notify about bridge VLANs

In commit 946a11e7 ("mlxsw: spectrum_span: Allow bridge for gretap
mirror"), mlxsw got support for offloading mirror-to-gretap such that
the underlay packet path involves a bridge. In that case, the offload is
also influenced by PVID setting of said bridge. However, changes to VLAN
configuration of the bridge itself do not generate switchdev
notifications, so there's no mechanism to prod mlxsw to update the
offload when these settings change.

In this patchset, the problem is resolved by distributing the switchdev
notification SWITCHDEV_OBJ_ID_PORT_VLAN also for configuration changes
on bridge VLANs. Since stacked devices distribute the notification to
lower devices, such event eventually reaches the driver, which can
determine whether it's a bridge or port VLAN by inspecting orig_dev.

To keep things consistent, the newly-distributed notifications observe
the same protocol as the existing ones: dual prepare/commit, with
-EOPNOTSUPP indicating lack of support, even though there's currently
nothing to prepare for and nothing to support. Correspondingly, all
switchdev drivers have been updated to return -EOPNOTSUPP for bridge
VLAN notifications.

In patches #1 and #2, the code base is changed to support the following
additions: functions br_switchdev_port_vlan_add() and
br_switchdev_port_vlan_del() are introduced to simplify sending
notifications; and br_vlan_add_existing() is introduced to later make it
simpler to add error-handling code for the case of configuring a
preexisting VLAN on bridge CPU port.

In patches #3-#6, respectively for mlxsw, rocker, DSA and DPAA2 ethsw,
the new notifications (which are not enabled yet) are ignored to
maintain the current behavior.

In patch #7, the notification is actually enabled.

In patch #8, mlxsw is changed to update offloads of mirror-to-gre also
for bridge-related notifications.

Changes from v3 to v4:

- In patch #1, separate variable declarations from program logic.
- Add patch #2.
- In patch #7, add error handling around a newly-introduced call to
  br_switchdev_port_vlan_add().
- Rephrase commit messages of patches #3-#6 to explain motivation for
  the change.

Changes from v2 to v3:

- Add a fallback definition for br_switchdev_port_obj_add() and
  br_switchdev_port_obj_del() when !CONFIG_NET_SWITCHDEV.

Changes from v1 to v2:

- Rename br_switchdev_port_obj_add() and br_switchdev_port_obj_del() to
  br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del(), and
  move from br_vlan.c to br_switchdev.c.
