Yong Li found that writes to the AST2500 strapping register were not
properly supported by the Aspeed pinctrl core and provided a patch to
rectify the problem. Several revisions of the patch were posted and
ultimately v4 should have been applied, however some unfortunate
liberal application of tags on my part lead to confusion between v3[1]
and v4[2].
Generate the diff between v3 and v4 to apply as a fixup patch.

In some scenarios, we should set some pins as input/output/pullup/pulldown
when the specified system goes into deep sleep mode, then when the system
goes into deep sleep mode, these pins will be set automatically by hardware.
That means some pins are not controlled by any specific driver in the OS, but
need to be controlled when entering sleep mode. Thus we introduce one sleep
state config into pinconf-generic for users to configure.

====================
mlx5-updates-2017-08-31 (GRE Offloads support)
This series provides the support for MPLS RSS and GRE TX offloads and
RSS support.
The first patch from Gal and Ariel provides the mlx5 driver support for
ConnectX capability to perform IP version identification and matching in
order to distinguish between IPv4 and IPv6 without the need to specify the
encapsulation type, thus perform RSS in MPLS automatically without
specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6
classification for inner GRE RSS.
2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets,
by reporting the needed netdev features.
3rd patch from Gal, Adds GRE inner RSS support by creating the needed device
resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic
and perform RSS hashing on the inner headers.
Improvement:
Testing 8 TCP streams bandwidth over GRE:
System: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
NIC: Mellanox Technologies MT28800 Family [ConnectX-5 Ex]
Before: 21.3 Gbps (Single RQ)
Now : 90.5 Gbps (RSS spread on 8 RQs)

Fix crash in linux PF driver when BARs have been cleared/de-programmed;
fail early init (prior to mapping BARs) if the BAR0 or
BAR1 registers are zero.
This situation can arise when the PF is added to a VM (PCI pass-through),
then a PF FLR is issued (in the VM). After this occurs, the BAR registers
will be zero. If we attempt to load the PF driver in the host
(after VM has been shutdown), the host can reset.

The original motivation for this change originated from Marc Gonzales
indicating that his network driver did not have its adjust_link callback
executing with phydev->link = 0 while he was expecting it.
PHYLIB has never made any such guarantees ever because phy_stop() merely just
tells the workqueue to move into PHY_HALTED state which will happen
asynchronously.

Introduce a new flow table and indirect TIRs which are used to hash the
inner packet headers of GRE tunneled packets.
When a GRE tunneled packet is received, the TTC flow table will match
the new IPv4/6->GRE rules which will forward it to the inner TTC table.
The inner TTC is similar to its counterpart outer TTC table, but
matching the inner packet headers instead of the outer ones (and does
not include the new IPv4/6->GRE rules).
The new rules will not add steering hops since they are added to an
already existing flow group which will be matched regardless of this
patch. Non GRE traffic will not be affected.
The inner flow table will forward the packet to inner indirect TIRs
which hash the inner packet and thus result in RSS for the tunneled
packets.

This change adds the ability for flow steering to classify IPv4/6
packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP
packets and hit IPv4/6 classification steering rules.
Since IP packets with MPLS tag header have MPLS ethertype, they
missed the IPv4/6 ethertype rule and ended up hitting the default
filter forwarding all the packets to the same single RQ (No RSS).
Since our device is able to look past the MPLS tag and identify the
next protocol we introduce this solution which replaces ethertype
matching by the device's capability to perform IP version
identification and matching in order to distinguish between IPv4 and
IPv6.
Therefore, when driver is performing flow steering configuration on the
device it will use IP version matching in IP classified rules instead
of ethertype matching which will cause relevant MPLS tagged packets to
hit this rule as well.
If the device doesn't support IP version matching the driver will fall back
to use legacy ethertype matching in the steering as before.

On the CP110 unit, which can be found on various Marvell platforms such
as the 7k and 8k (currently), a comphy (common PHYs) hardware block can
be found. This block provides a number of PHYs which can be used in
various modes by other controllers (network, SATA ...). These common
PHYs must be configured for the controllers using them to work correctly
either at boot time, or when the system runs to switch the mode used.
This patch adds a driver for this comphy hardware block, providing
callbacks for the its PHYs so that consumers can configure the modes
used.
As of this commit, two modes are supported by the comphy driver: sgmii
and 10gkr.

When changing from switchdev to legacy mode, all the representor port

process is removing the neigh entries and the hash table containing them.
However, a representor neigh entry might be linked to the uplink port
hash table and if the uplink nic is cleaned first the cleaning of the
representor will end up in null deref.

There is an issue where the firmware fails during mlx5_load_one,
the health_care timer detects the issue and schedules a health_care call.
Then the mlx5_load_one detects the issue, cleans up and quits. Then
the health_care starts and calls mlx5_unload_one to clean up the resources
that no longer exist and causes kernel panic.
The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set
after mlx5_load_one fails. The solution is removing the bit
MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the
bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN
is redundant and we can use MLX5_INTERFACE_STATE_UP instead.

Support for ISSI version 0 was recently broken as the arm_srq_cmd
command, which is used only for ISSI version 0, was given the opcode
for ISSI version 1 instead of ISSI version 0.
Change arm_srq_cmd to use the correct command opcode for ISSI version
0.

Current code doesn't report DCB_CAP_DCBX_HOST capability when query
through getcap. User space lldptool expects capability to have HOST mode
set when it wants to configure DCBX CEE mode. In absence of HOST mode
capability, lldptool fails to switch to CEE mode.
This fix returns DCB_CAP_DCBX_HOST capability when port's DCBX
controlled mode is under software control.

qos capability is the master capability bit that determines
if the DCBX is supported for the PCI function. If this bit is off,
driver cannot run any dcbx code.

When moving the IRDA code out of net/ into drivers/staging/irda/net, the
link order changes when IRDA is built into the kernel. That causes a
kernel crash at boot time as netfilter isn't initialized yet.
To fix this, move the init call level of the irda core to be
device_initcall() as the link order keeps this being initialized at the
correct time.

It is quite common for ti_cm_get_macid() to fail on some of the
platforms it is invoked on. They include any platform where
mac address is not part of SoC register space.
On these platforms, mac address is read and populated in
device-tree by bootloader. An example is TI DA850.
Downgrade the severity of message to "information", so it does
not spam logs when 'quiet' boot is desired.
