This patch enables the interrupts for internal phy link detection for
LAN937x. The interrupt enable bits are active low. There is global
interrupt mask for each port. And each port has the individual interrupt
mask for TAS. QCI, SGMII, PTP, PHY and ACL.
The first level of interrupt domain is registered for global port
interrupt and second level of interrupt domain for the individual port
interrupts. The phy interrupt is enabled in the lan937x_mdio_register
function. Interrupt from which port is raised will be detected based on
the interrupt host data.

struct ksz_port doesn't have reference to ksz_device as of now. In order
to find out from which port interrupt has triggered, we need to pass the
struct ksz_port as a host data. When the interrupt is triggered, we can
get the port from which interrupt triggered, but to identify it is phy
interrupt we have to read status register. The regmap structure for
accessing the device register is present in the ksz_device struct. To
access the ksz_device from the ksz_port, the reference is added to it
with port number as well.

Use a more standard form for the VT version number comments.
One slight oddball case is the dp_max_link_rate that had two
version numbers (216/230) and a platform name (GLK). The
story goes that the field was introduced in the spec in
version 216, along with a note that it's used on CNL+. Later
in version 230 the definition of the bit was changed in
bacakwards incompatible ways and the CNL note disappeard.
For us the original CNL+ note in the header got changed to
to GLK+ when all CNL support was dropped from the codebase.
We do still need (and have) handling for both the 216+ and
the 230+ defintions (parse_bdb_216_dp_max_link_rate() vs.
parse_bdb_230_dp_max_link_rate()).

When the RDMA auxiliary driver probes, it sets its profile based on
devlink driverinit value. The latter might not be in sync with FW yet
(In case devlink reload is not performed), thus causing a mismatch
between RDMA driver and FW. This results in the following FW syndrome
when the RDMA driver tries to adjust RoCE state, which fails the probe:
"0xC1F678 | modify_nic_vport_context: roce_en set on a vport that
doesn't support roce"
To prevent this, select the PF profile based on FW RoCE capability
instead of relying on devlink driverinit value.
To provide backward compatibility of the RoCE disable feature, on older
FW's where roce_rw is not set (FW RoCE capability is read-only), keep
the current behavior e.g., rely on devlink driverinit value.

Fix a nested dead lock as part of ODP flow by using mmput_async().
From the below call trace [1] can see that calling mmput() once we have
the umem_odp->umem_mutex locked as required by
ib_umem_odp_map_dma_and_lock() might trigger in the same task the
exit_mmap()->__mmu_notifier_release()->mlx5_ib_invalidate_range() which
may dead lock when trying to lock the same mutex.
Moving to use mmput_async() will solve the problem as the above
exit_mmap() flow will be called in other task and will be executed once
the lock will be available.

Using a little logic we can simplify gsi_channel_trans_last().
The first condition in that function looks like this:
if (trans_info->allocated_id != trans_info->free_id)
And if that's false, we proceed to the next one:
if (trans_info->committed_id != trans_info->allocated_id)
Failure of the first test implies:
trans_info->allocated_id == trans_info->free_id
And therefore, the second one can be rewritten this way:
if (trans_info->committed_id != trans_info->free_id)
Substituting free_id for allocated_id and committed_id can also be
done in the code blocks executed when these conditions yield true.
The net result is that all three blocks for TX endpoints can be
consolidated into just one.
The two blocks of code at the end of that function (used for both TX
and RX channels) can be similarly consolidated into a single block.

When quiescing a channel, we find the "last" transaction, which is
the latest one to have been allocated. (New transaction allocation
will have been prevented by the time this is called.)
Currently we do this by looking for the first non-empty transaction
list in each state, then return the last entry from that last.
Instead, determine the last entry in each list (if any) and return
that entry if found.
Temporarily (locally) introduce list_last_entry_or_null() as a
helper for this, mirroring list_first_entry_or_null(). This macro
definition will be removed by an upcoming patch.

I believe that the only reason the driver, instead of the standard

wanted to set up a pretty consumer name for the GPIO, and we now have

The ohci retaining bogus hardware states cause usb disconnect devices
connected before hibernation(s4), this issue occur when ohci-platform
driver build as a module and the built-in ohci-platform driver will
re probe and re enumerate the devices, so there will be no such problem.
Avoid retaining bogus hardware states during resume-from-hibernation.
Previously we had reset the hardware as part of preparing to reinstate
the snapshot image. But we can do better now with the new PM framework,
since we know exactly which resume operations are from hibernation.
According to the commit 'cd1965db054e ("USB: ohci: move ohci_pci_{
suspend,resume} to ohci-hcd.c")' and commit '6ec4beb5c701 ("USB: new
flag for resume-from-hibernation")', the flag "hibernated" is for
resume-from-hibernation and it should be true when usb resume from disk.
When this flag "hibernated" is set, the drivers will reset the hardware
to get rid of any existing state and make sure resume from hibernation
re-enumerates everything for ohci.

driver_override field. When commit 23d99baf9d72 ("PCI: Use
driver_set_override() instead of open-coding") moved the PCI core to use
the driver core function instead of hand-rolling their own handler, this
showed up as a regression from some userspace tools, like DPDK.
Fix this up by actually looking at the length of the string first
instead of trusting that userspace got it correct.

When registering a connector, the kernel sends a hotplug uevent in
drm_connector_register(). When unregistering a connector, drivers
are expected to send a uevent as well. However, user-space has no way
to figure out that the connector isn't registered anymore: it'll still
be reported in GETCONNECTOR IOCTLs.
The documentation for DRM_CONNECTOR_UNREGISTERED states:
> The connector […] has since been unregistered and removed from
> userspace, or the connector was unregistered before it had a chance
> to be exposed to userspace

Asus UM325UAZ has GPIO 18 programmed as both an interrupt and a wake
source, but confirmed with internal team on this design this pin is
floating and shouldn't have been programmed. This causes lots of
spurious IRQs on the system and horrendous battery life.
Add a quirk to ignore attempts to program this pin on this system.

gpiolib-acpi already had support for ignoring a pin for wakeup, but
if an OEM configures a floating pin as an interrupt source then
stopping it from being a wakeup won't do much good to stop the
interrupt storm.
Add support for a module parameter and quirk infrastructure to
ignore interrupts as well.

On system suspend when system memory is low then i915_gem_obj_copy_ttm()
could fail trying to backup a lmem obj. GEM_WARN_ON() is not enough,
suspend shouldn't continue if i915_ttm_backup() throws an error.
v2: Keep the fdo issue till we have a igt test(Matt).
v3: Use %pe(Andrzej)

Convert the Altera Triple Speed Ethernet Controller to phylink.
This controller supports MII, GMII and RGMII with its MAC, and
SGMII + 1000BaseX through a small embedded PCS.
The PCS itself has a register set very similar to what is found in a
typical 802.3 ethernet PHY, but this register set memory-mapped instead
of lying on an mdio bus.

The Altera Triple Speed Ethernet has a SGMII/1000BaseC PCS that can be
integrated in several ways. It can either be part of the TSE MAC's
address space, accessed through 32 bits accesses on the mapped mdio
device 0, or through a dedicated 16 bits register set.
This driver allows using the TSE PCS outside of altera TSE's driver,
since it can be used standalone by other MACs.

When ns_ip6_target was set, the ipv6_dev_get_saddr() will be called to get
available source address and send IPv6 neighbor solicit message.
If the target is global address, ipv6_dev_get_saddr() will get any
available src address. But if the target is link local address,
ipv6_dev_get_saddr() will only get available address from our interface,
i.e. the corresponding bond interface.
But before bond interface up, all the address is tentative, while
ipv6_dev_get_saddr() will ignore tentative address. This makes we can't
find available link local src address, then bond_ns_send() will not be
called and no NS message was sent. Finally bond interface will keep in
down state.
Fix this by sending NS with unspecified address if there is no available
source address.
