Move the requesting of DMA channels further down from 'probe' to
'pcm_new'. This is to spare the allocated DMA channel resources as we
typically only ever use one or two of the clusters for PCM streaming.
Before we would request DMA channels for all clusters.
(This is prompted by a change in the Audio DMA Controller driver, which
will now be allocating cache SRAM to channels.)

net: dsa: microchip: lan937x: enable interrupt for internal phy link detection
This patch series enables the internal phy link detection for lan937x using the
interrupt method. lan937x acts as the interrupt controller for the internal
ports and phy, the irq_domain is registered for the individual ports and in
turn for the individual port interrupts.
RFC v3 -> Patch v1
- Removed the RFC v3 1/3 from the series - changing exit from reset
- Changed the variable name in ksz_port from irq to pirq
- Added the check for return value of irq_find_mapping during phy irq
registeration.
- Moved the clearing of POR_READY_INT from girq_thread_fn to
lan937x_reset_switch

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.

get the port from which interrupt triggered, but to identify it is phy

accessing the device register is present in the ksz_device struct. To

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.

exit_mmap()->__mmu_notifier_release()->mlx5_ib_invalidate_range() which

This series starts using those IDs instead of the lists used

The completed transaction list is used in gsi_channel_trans_complete()
to return the next transaction in completed state.
Add some temporary checks to verify the transaction indicated by the
completed ID matches the one first in this list.
Similarly, we use the pending and completed transaction lists when

Signed-off-by: David S. Miller <davem@davemloft.net>
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

I would like to stop exporting OF-specific devm_gpiod_get_from_of_node()
so that gpiolib can be cleaned a bit, so let's switch to the generic
device property API.
I believe that the only reason the driver, instead of the standard
devm_gpiod_get(), used devm_gpiod_get_from_of_node() is because it
wanted to set up a pretty consumer name for the GPIO, and we now have
a special API for that.

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 'cd1965db05 ("USB: ohci: move ohci_pci_{
suspend,resume} to ohci-hcd.c")' and commit '6ec4beb5c7 ("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.

Sometimes drivers are missing logs when they return EINVAL.
Printing the failure here in common code can help understand where
EINVAL is coming from.
All other atomic_check() calls in this file already have similar
logging.

Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup())
leaks a dentry and with a hotplug stress test, the machine eventually
runs out of memory.
Fix this up by using the newly created debugfs_lookup_and_remove() call
instead which properly handles the dentry reference counting logic.

There is a very common pattern of using
debugfs_remove(debufs_lookup(..)) which results in a dentry leak of the
dentry that was looked up. Instead of having to open-code the correct
pattern of calling dput() on the dentry, create
debugfs_lookup_and_remove() to handle this pattern automatically and
properly without any memory leaks.

Python likes to send an empty string for some sysfs files, including the
driver_override field. When commit 23d99baf9d ("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.
