When the GPU is reset both the current exec state, as well as all MMU
state is lost. Move the driver side state tracking into the reset function
to keep hardware and software state from diverging.

The MMU state may be kept across a runtime suspend/resume cycle, as we
avoid a full hardware reset to keep the latency of the runtime PM small.
Don't pretend that the MMU state is lost in driver state. The MMU
context is pushed out when new HW jobs with a different context are
coming in. The only exception to this is when the GPU is unbound, in
which case we need to make sure to also free the last active context.

While the DMA frontend can only be active when the MMU context is set, the
reverse isn't necessarily true, as the frontend can be stopped while the
MMU state is kept. Stop treating mmu_context being set as a indication that
the frontend is running and instead add a explicit property.

The prev context is the MMU context at the time of the job
queueing in hardware. As a job might be queued multiple times
due to recovery after a GPU hang, we need to make sure to put
the stale prev MMU context from a prior queuing, to avoid the
reference and thus the MMU context leaking.

extends the owl loader to fetch important pci initialization
values - which are stored together with the calibration data -
through the nvmem subsystem.
This allows for much faster WIFI/ath9k initializations on devices
that do not require to perform any post-processing (like XOR'ing/
reversal or unpacking)... than the current way through the
firmware_request which involves the filesystem/userspace.

On most embedded ath9k devices (like range extenders,
routers, accesspoints, ...) the calibration data is
stored in a MTD partitions named "ART", or "caldata"/
"calibration".
Since commit 4b361cfa8624 ("mtd: core: add OTP nvmem provider support"):
All MTD partitions are all automatically available through
the nvmem subsystem.
This feature - together with an nvmem cell definition either
in the platform data or via device-tree allows drivers to get
the data necessary for initializing the WIFI, without having
to wait around for the filesystem and userspace to do
the extractions.

This reverts commit 3ac8eed62596387214869319379c1fcba264d8c6, which did
more than it said on the box, and not only it replaced to_phy_driver
with phydev->drv, but it also removed the "!drv" check, without actually
explaining why that is fine.
That patch in fact breaks suspend/resume on any system which has PHY
devices with no drivers bound.
The stack trace is:
Unable to handle kernel NULL pointer dereference at virtual address 00000000000000e8
pc : mdio_bus_phy_suspend+0xd8/0xec
lr : dpm_run_callback+0x38/0x90

dpm_suspend_start+0x7c/0xa0
suspend_devices_and_enter+0x13c/0x540
pm_suspend+0x2a4/0x330
Examples why that assumption is not fine:
- There is an MDIO bus with a PHY device that doesn't have a specific
PHY driver loaded, because mdiobus_register() automatically creates a
PHY device for it but there is no specific PHY driver in the system.
Normally under those circumstances, the generic PHY driver will be
bound lazily to it (at phy_attach_direct time). But some Ethernet
drivers attach to their PHY at .ndo_open time. Until then it, the
to-be-driven-by-genphy PHY device will not have a driver. The blamed
patch amounts to saying "you need to open all net devices before the
system can suspend, to avoid the NULL pointer dereference".
- There is any raw MDIO device which has 'plausible' values in the PHY
ID registers 2 and 3, which is located on an MDIO bus whose driver
does not set bus->phy_mask = ~0 (which prevents auto-scanning of PHY
devices). An example could be a MAC's internal MDIO bus with PCS
devices on it, for serial links such as SGMII. PHY devices will get
created for those PCSes too, due to that MDIO bus auto-scanning, and
although those PHY devices are not used, they do not bother anybody
either. PCS devices are usually managed in Linux as raw MDIO devices.
Nonetheless, they do not have a PHY driver, nor does anybody attempt
to connect to them (because they are not a PHY), and therefore this
patch breaks that.
The goal itself of the patch is questionable, so I am going for a
straight revert. to_phy_driver does not seem to have a need to be
replaced by phydev->drv, in fact that might even trigger code paths
which were not given too deep of a thought.
For instance:
phy_probe populates phydev->drv at the beginning, but does not clean it
up on any error (including EPROBE_DEFER). So if the phydev driver
requests probe deferral, phydev->drv will remain populated despite there
being no driver bound.
If a system suspend starts in between the initial probe deferral request
and the subsequent probe retry, we will be calling the phydev->drv->suspend
method, but _before_ any phydev->drv->probe call has succeeded.
That is to say, if the phydev->drv is allocating any driver-private data
structure in ->probe, it pretty much expects that data structure to be
available in ->suspend. But it may not. That is a pretty insane
environment to present to PHY drivers.
In the code structure before the blamed patch, mdio_bus_phy_may_suspend
would just say "no, don't suspend" to any PHY device which does not have
a driver pointer _in_the_device_structure_ (not the phydev->drv). That
would essentially ensure that ->suspend will never get called for a
device that has not yet successfully completed probe. This is the code
structure the patch is returning to, via the revert.

Commit 375553a93201 ("PCI: Setup ACPI fwnode early and at the same time
with OF") added a call to pci_set_acpi_fwnode() in pci_setup_device(),
which unconditionally clears any fwnode previously set by
pci_set_of_node().
pci_set_acpi_fwnode() looks for ACPI_COMPANION(), which only returns the
existing fwnode if it was set by ACPI_COMPANION_SET(). If it was set by
OF instead, ACPI_COMPANION() returns NULL and pci_set_acpi_fwnode()
accidentally clears the fwnode. To fix this, look for any fwnode instead
of just ACPI companions.
Fixes a virtio-iommu boot regression in v5.15-rc1.

Implement support for ethtool_ops::reset in order to reset transceiver
modules. The module backing the netdev is reset when the 'ETH_RESET_PHY'
flag is set. After a successful reset, the flag is cleared by the driver
and other flags are ignored. This is in accordance with the interface
documentation:
"The reset() operation must clear the flags for the components which
were actually reset. On successful return, the flags indicate the
components which were not reset, either because they do not exist in the
hardware or because they cannot be reset independently. The driver must
never reset any components that were not requested."
Reset is useful in order to allow a module to transition out of a fault
state. From section 6.3.2.12 in CMIS 5.0: "Except for a power cycle, the
only exit path from the ModuleFault state is to perform a module reset
by taking an action that causes the ResetS transition signal to become
TRUE (see Table 6-11)".
An error is returned when the netdev is administratively up:
# ip link set dev swp11 up
# ethtool --reset swp11 phy
ETHTOOL_RESET 0x40
Cannot issue ETHTOOL_RESET: Invalid argument
# ip link set dev swp11 down
# ethtool --reset swp11 phy
ETHTOOL_RESET 0x40
Components reset: 0x40
An error is returned when the module is shared by multiple ports (split
ports) and the "phy-shared" flag is not set:
# devlink port split swp11 count 4
# ethtool --reset swp11s0 phy
ETHTOOL_RESET 0x40
Cannot issue ETHTOOL_RESET: Invalid argument
# ethtool --reset swp11s0 phy-shared

Components reset: 0x400000
# devlink port unsplit swp11s0

An error is also returned when one of the ports using the module is
administratively up:
# devlink port split swp11 count 4
# ip link set dev swp11s1 up
# ethtool --reset swp11s0 phy-shared

Commit 961cf99a074f ("mlxsw: core: Re-order initialization sequence")
changed the initialization sequence so that the switch driver (e.g.,
mlxsw_spectrum) is initialized before registration with the hwmon and
thermal subsystems.
This was done in order to avoid situations where hwmon/thermal code uses
features not supported by current firmware version, which is only
validated as part of switch driver initialization.
Later, commit b79cb787ac70 ("mlxsw: Move fw flashing code into core.c")
moved firmware validation and flashing code from the switch driver to
mlxsw_core so that it is performed before driver initialization.
Therefore, change the initialization sequence back to its original form.
In addition to being more straightforward, it will allow us to simplify
parts of the code in subsequent patches and future patchsets.

The devlink parameters were published in two steps despite being static
and known in advance.
First step was to use devlink_params_publish() which iterated over all
known up to that point parameters and sent notification messages.
In second step, the call was devlink_param_publish() that looped over
same parameters list and sent notification for new parameters.
In order to simplify the API, move devlink_params_publish() to be called
when all parameters were already added and save the need to iterate over
parameters list again.
As a side effect, this change fixes the error unwind flow in which
parameters were not marked as unpublished.

Pass the crtc+cpu_transcoder rather than the crtc state to
intel_dsc_power_domain(). This should allow us to reuse it
during readout as well.

PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder.
Bigjoiner is making life even more confusing by introducing
a N:1 relationship between pipes and transcoders. In that case
we only enable/configure the transcoder corresponding to the
master pipe. Let's do some renames to make it clear we're dealing
with the transcoder rather than pipe when it comes to
PIPECONF/TRANSCONF.
I decided to leave the _cpu_ part out from the function/macro
names since the PCH transcoder related stuff already has a
_pch_ in their name. So shouldn't be possible to confuse them.

GPU wedged flag now set on driver unregister to prevent from further
using the GPU can be then cleared unintentionally when calling
__intel_gt_unset_wedged() still before the flag is finally marked
unrecoverable. We need to have it marked unrecoverable earlier.
Implement that by replacing a call to intel_gt_set_wedged() in
intel_gt_driver_unregister() with intel_gt_set_wedged_on_fini().
With the above in place, intel_gt_set_wedged_on_fini() is now called
twice on driver remove, second time from __intel_gt_disable(). This
seems harmless, while dropping intel_gt_set_wedged_on_fini() from
__intel_gt_disable() proved to break some driver probe error unwind
paths as well as mock selftest exit path.

If cma_listen_on_all() fails it leaves the per-device ID still on the
listen_list but the state is not set to RDMA_CM_ADDR_BOUND.
When the cmid is eventually destroyed cma_cancel_listens() is not called
due to the wrong state, however the per-device IDs are still holding the
refcount preventing the ID from being destroyed, thus deadlocking:

Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.
So this patch checks hid_device's input is non empty before it's been used.

issue:
in cleanup_job the cancle_delayed_work will cancel a TO timer
even the its corresponding job is still running.
fix:
do not cancel the timer in cleanup_job, instead do the cancelling
only when the heading job is signaled, and if there is a "next" job
we start_timeout again.
v2:
further cleanup the logic, and do the TDR timer cancelling if the signaled job
is the last one in its scheduler.
v3:
change the issue description
remove the cancel_delayed_work in the begining of the cleanup_job
recover the implement of drm_sched_job_begin.
v4:
remove the kthread_should_park() checking in cleanup_job routine,
we should cleanup the signaled job asap
TODO:
1)introduce pause/resume scheduler in job_timeout to serial the handling
of scheduler and job_timeout.
2)drop the bad job's del and insert in scheduler due to above serialization
(no race issue anymore with the serialization)
