Move initialization of submission-related spinlock, lists and workers to
init_early. This fixes an issue where if the GuC init fails we might
still try to get the lock in the context cleanup code. Note that it is
safe to call the GuC context cleanup code even if the init failed
because all contexts are initialized with an invalid GuC ID, which will
cause the GuC side of the cleanup to be skipped, so it is easier to just
make sure the variables are initialized than to special case the cleanup
to handle the case when they're not.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
Qualcomm driver updates for v5.18
This refactors the Qualcomm mdt file loader, to partially decouple it
from the SCM peripheral-authentication-service. This is needed as newer
platforms, such as the Qualcomm SM8450, require the metadata to remain
accessible to TrustZone during a longer time. This is followed by the
introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1).
It changes the way hardware version differences are handled in the LLCC
driver and introduces support for Qualcomm SM8450. While updating the dt
binding for LLCC it also introduces the missing SM8350 compatible.
The ocmem and aoss drivers gains missing put_device() calls and rpmpd
gains a missing check for kcalloc() failure.
The SPM driver is updated to avoid instantiating the SPM cpuidle devices
if the CPUs aren't controlled by SPM, such as when Snapdragon 8916
operates in 32-bit mode without PSCI.
The RPM power-domain driver gains MSM8226 support.
Lastly the socinfo driver gains knowledge about a few new SoCs and
PMICs.

Currently there are functions in iavf_virtchnl.c for polling specific
virtchnl receive events. These are all assigning iavf_status values to
int values. Fix this and explicitly assign int values if iavf_status
is not IAVF_SUCCESS.
Also, refactor a small amount of duplicated code that can be reused by
all of the previously mentioned functions.
Finally, fix some spacing errors for variable assignment and get rid of
all the goto statements in the refactored functions for clarity.

Several functions in the iAVF core files take status values of the enum
iavf_status and convert them into integer values. This leads to
confusion as functions return both Linux errno values and status codes
intermixed. Reporting status codes as if they were "errno" values can
lead to confusion when reviewing error logs. Additionally, it can lead
to unexpected behavior if a return value is not interpreted properly.
Fix this by introducing iavf_status_to_errno, a switch that explicitly
converts from the status codes into an appropriate error value. Also
introduce a virtchnl_status_to_errno function for the one case where we
were returning both virtchnl status codes and iavf_status codes in the
same function.

In order to handle the capability exchange necessary for
VIRTCHNL_VF_OFFLOAD_VLAN_V2, the driver must send
a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS message. This must occur prior to
__IAVF_CONFIG_ADAPTER, and the driver must wait for the response from
the PF.
To handle this, the __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state was
introduced. This state is intended to process the response from the VLAN
V2 caps message. This works ok, but is difficult to extend to adding
more extended capability exchange.
Existing (and future) AVF features are relying more and more on these
sort of extended ops for processing additional capabilities. Just like
VLAN V2, this exchange must happen prior to __IAVF_CONFIG_ADPATER.
Since we only send one outstanding AQ message at a time during init, it
is not clear where to place this state. Adding more capability specific
states becomes a mess. Instead of having the "previous" state send
a message and then transition into a capability-specific state,
introduce __IAVF_EXTENDED_CAPS state. This state will use a list of
extended_caps that determines what messages to send and receive. As long
as there are extended_caps bits still set, the driver will remain in
this state performing one send or one receive per state machine loop.
Refactor the VLAN V2 negotiation to use this new state, and remove the
capability-specific state. This makes it significantly easier to add
a new similar capability exchange going forward.
Extended capabilities are processed by having an associated SEND and
RECV extended capability bit. During __IAVF_EXTENDED_CAPS, the
driver checks these bits in order by feature, first the send bit for
a feature, then the recv bit for a feature. Each send flag will call
a function that sends the necessary response, while each receive flag
will wait for the response from the PF. If a given feature can't be
negotiated with the PF, the associated flags will be cleared in
order to skip processing of that feature.

A flag query helper was actually writing to the flags word rather than
just reading. Fix that. Also update the function's comment as it was
out of date.
NB: No need for a 'Fixes' tag. The test was only ever used inside a
BUG_ON during context registration. Rather than asserting that the
condition was true, it was making the condition true. So, in theory,
there was no consequence because we should never have hit a BUG_ON
anyway. Which means the write should always have been a no-op.

Lock the adapter while setting the suspended flag, to ensure that other
locked code always sees the change immediately, rather then possibly using
a stale value.
This involves splitting the suspend/resume callbacks into separate runtime
and normal suspend/resume calls. This is necessary because i2c_dw_xfer()
will get called by the i2c-core with the adapter locked and it in turn
calls the runtime-resume callback through pm_runtime_get_sync().
So the runtime versions of the suspend/resume callbacks cannot take
the adapter-lock. Note this patch simply makes the runtime suspend/resume
callbacks not deal with the suspended flag at all. During runtime the
pm_runtime_get_sync() from i2c_dw_xfer() will always ensure that the
adapter is resumed when necessary.
The suspended flag check is only necessary to check proper suspend/resume
ordering during normal suspend/resume which makes the pm_runtime_get_sync()
call a no-op.

Kernel test robot reported incorrect type in argument 1 of readl(), but
more importantly it brought attention that MMIO accessor shouldn't be
used in this case, since req->hdr.status is part of a command-response
buffer in system memory.
Since its value may be altered by PSP outside of the scope of current
thread (somehow similar to IRQ handler case), we need to use
READ_ONCE() to ensure compiler won't optimize this call.
Fix also 'status' variable type to reflect that corresponding field in
command-response buffer is platform-independent u32.

A PM domain managed by genpd may support multiple idlestates (power-off
states). During genpd_power_off() a genpd governor may be asked to select
one of the idlestates based upon the dev PM QoS constraints, for example.
However, there is a problem with the behaviour around this in genpd. More
precisely, a parent-domain is allowed to be powered off, no matter of what
idlestate that has been selected for the child-domain.
For the stm32mp1 platform from STMicro, this behaviour doesn't play well.
Instead, the parent-domain must not be powered off, unless the deepest
idlestate has been selected for the child-domain. As the current behaviour
in genpd is quite questionable anyway, let's simply change it into what is
needed by the stm32mp1 platform.
If it surprisingly turns out that other platforms may need a different
behaviour from genpd, then we will have to revisit this to find a way to
make it configurable.

This board definition was originally created for mobile devices to
designate default link power managmeent policy to influence runtime
power consumption.
As this is interesting for more than just mobile designs, rename the
board to `board_ahci_low_power` to make it clear it is about default
policy.

Multitouch devices in hybrid mode are reporting multiple times the

HID_QUIRK_INVERT is kind of complex to deal with and was bogus.
Furthermore, it didn't make sense to use a global per struct hid_device
quirk for something dynamic as the current state.
Store the current tool information in the report itself, and re-order
the processing of the fields to enforce having all the tablet "state"
fields before getting to In Range and other input fields.
This way, we now have all the information whether a tool is present
or not while processing In Range.
This new behavior enforces that only one tool gets forwarded to userspace
at the same time, and that if either eraser or invert is set, we enforce
BTN_TOOL_RUBBER.
Note that the release of the previous tool now happens in its own EV_SYN
report so userspace doesn't get confused by having 2 tools.
These changes are tested in the following hid-tools regression tests:

When a device exposes both Invert and InRange, Invert must be processed
before InRange. If we keep the order of the device and we process them
out of order, InRange will first set BTN_TOOL_PEN, and then Invert will
set BTN_TOOL_RUBBER. Userspace knows how to deal with that situation,
but fixing it in the kernel is now easier.

Now that we have a list of fields/usages by priority order,
walk through that list to process the inputs instead of using the
order provided by the manufacturer.
Note that this changes the way we update the values in the struct
hid_field:
Previously, once a field was processed, we updated the new values.
Now we need to wait for the entire report to be processed to update
the values.
I don't think it will be an issue: because we were relying on the device
ordering, there were no guarantees to have a field stored before an other.
Which is why we introduced .report() in drivers to have those values
updated.

This will be used in a later commit:
we build a list of input fields (and usage_index) that is ordered based
on a usage priority.
Changing the usage priority allows to re-order the processed list, meaning
that we can enforce some usages to be process before others.
For instance, before processing InRange in the HID tablets, we need to
know if we are using the eraser (side or button). Enforcing a higher
(lower number) priority for Invert allows to force the input stack to
process that field before.

Instead of using multiple `if (a == b)`, use the switch statement
which has been done exactly for that.
There should be no functional change (I don't expect moving down

This is a preparatory patch for being able to process the usages
out of order. We split the retrieval of the data in a separate function
and also split out the processing of the usages depending if the field
is an array or a variable.

Booting msm8939 on tip-of-tree I encountered the following error.
[ 1.212340] qnoc-msm8939 580000.interconnect_mm: can't request region for resource [mem 0x00580000-0x0059407f]
[ 1.212391] qnoc-msm8939 580000.interconnect_mm: Cannot ioremap interconnect bus resource
[ 1.221524] qnoc-msm8939: probe of 580000.interconnect_mm failed with error -16
Initially I thought this was a bug with the interconnect driver but,
examining it a bit more I realized the DTS I was working with based on
downstream, declares snoc and snoc_mm as existing at the same address
range.
When we were developing the DTS for 8939 we weren't using the common rpm
interconnect driver so we never saw the ioremap collision.
Taking a hard look at the qcom documentation as well as the downstream code
we see that yes downstream declares snoc and snoc_mm separately but, also
at the same overlapping address.
The qcom documentation for performance points for msm8936/msm8939 snoc,
deliniates snoc_mm as simply two new performance-points i.e. a faster GPLL0
vote associated with new multi-media devices attached to the snoc.
In other words the snoc had two new RPM vote indices added to it, to
represent the higher performance clocks, should one of the multi-media IP
blocks call for it.
We can fix the ioremap collision and still represent the two higher
performance point clock votes by coalsecing snoc and snoc_mm into snoc. The
DTS clock references will take care of the appropriate votes.

The driver creates the top row map sysfs attribute in input_configured()
method; unfortunately we do not have a callback that is executed when HID
interface is unbound, thus we are leaking these sysfs attributes, for
example when device is disconnected.
To fix it let's switch to managed version of adding sysfs attributes which
will ensure that they are destroyed when the driver is unbound.
