Pull driver core fixes from Greg KH:
"Here are some small driver core fixes for 5.15-rc6, all of which have
been in linux-next for a while with no reported issues.
They include:
- kernfs negative dentry bugfix
- simple pm bus fixes to resolve reported issues"

The simple-pm-bus driver is mandatory for CONFIG_OF based platforms to work
with fw_devlink. So, always compile it in for CONFIG_OF and delete the
config since it's no longer necessary.

fw_devlink could end up creating device links for bus only devices.
However, bus only devices don't get probed and can block probe() or
sync_state() [1] call backs of other devices. To avoid this, probe these
devices using the simple-pm-bus driver.
However, there are instances of devices that are not simple buses (they get
probed by their specific drivers) that also list the "simple-bus" (or other
bus only compatible strings) in their compatible property to automatically
populate their child devices. We still want these devices to get probed by
their specific drivers. So, we make sure this driver only probes devices
that are only buses.

Commit 94f6345712b3 ("bus: ti-sysc: Implement quirk handling for
CLKDM_NOAUTO") should have also added the quirk for dra7 dcan1 in
addition to dcan2 for errata i893 handling.
Let's also pass the quirk flag for legacy mode booting for if "ti,hwmods"
dts property is used with related dcan hwmod data. This should be only
needed if anybody needs to git bisect earlier stable trees though.

For the smartreflex device, we need to disable smartreflex on SoC idle,
and have been using pm_runtime_irq_safe() to do that. But we want to
remove the irq_safe usage as PM runtime takes a permanent usage count
on the parent device with it.
In order to remove the need for pm_runtime_irq_safe(), let's gate
the clock directly in the driver. This removes the need to call PM runtime
during idle, and allows us to switch to using CPU_PM in the following
patch.
Note that the smartreflex interconnect target module is configured for smart
idle, but the clock does not have autoidle capability, and needs to be gated
manually. If the clock supported autoidle, we would not need to even gate
the clock.
With this change, we can now remove the related quirk flags for ti-sysc
also.

The McASP module in OMAP4 does not work if the SIDLE mode is enabled, most
like due to module integration issue that the signaling is not working
correctly.
Add a quirk for the module to select only NOIDLE mode when it is in use.

IXP4xx driver updates for modernizing the IXP4xx platforms,
taregeted for v5.15:
- Add DT bindings to the expansion bus and PATA libata driver.
- Add a new expansion bus driver.
- Rewrite the watchdog driver to use the watchdog core and
spawn from the timer (clocksource) driver.
- Refactor the PATA/libata driver to probe from the device
tree and use the expansion bus driver to manipulate chip
select timings directly.

The Intel IXP4xx SoCs have an expansion bus that is usually just
used for flash memory and configured by the boot loaders and can
be accessed using the "simple-bus".
However some devices need more elaborate configuration and then we
need to provide a proper 3-unit address space indicating chip
select for each device and provide timing and similar information.

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

Pull char / misc driver updates from Greg KH:
"Here is the big set of char/misc driver changes for 5.15-rc1.
Lots of different driver subsystems are being updated in here,
notably:
- mhi subsystem update
- fpga subsystem update
- coresight/hwtracing subsystem update
- interconnect subsystem update
- nvmem subsystem update
- parport drivers update
- phy subsystem update
- soundwire subsystem update
and there are some other char/misc drivers being updated as well:
- binder driver additions
- new misc drivers
- lkdtm driver updates
- mei driver updates
- sram driver updates
- other minor driver updates.
Note, there are no habanalabs driver updates in this pull request,
that will probably come later before -rc1 is out in a different
request.
All of these have been in linux-next for a while with no reported
problems"

This reverts commit 0092a1e3f7636ff4e202a41b0320690699247e22
This should be reverted in the char-misc-next branch to make merging
with Linus's branch possible due to issues with the mhi code that was
found in the networking tree.

Improve error message to be more descriptive if a failure occurs
with an invalid power up execution environment. Additionally, add
a debug log to print the execution environment and MHI state
before a power up is attempted to confirm if the device is in an
expected state. This helps clarify reasons for power up failures
such as the device being found in a PBL or Emergency Download
Mode execution environment and the host expected a full power up
with Pass-Through and no image loading involved.

When obtaining the BHI or BHIe offsets during the power up
preparation phase, range checks are missing. These can help
controller drivers avoid accessing any address outside of the
MMIO region. Ensure that mhi_cntrl->reg_len is set before MHI
registration as it is a required field and range checks will
fail without it.

Set the BHI and/or BHIe offsets in mhi_prepare_for_power_up(),
rearrange the function, and remove the equivalent from
mhi_async_power_up(). This helps consolidate multiple checks
in different parts of the driver and can help MHI fail early on
before power up begins if the offsets are not read correctly.

Currently, the MHI controller driver defines which channels should
have their inbound buffers allocated and queued. But ideally, this is
something that should be decided by the MHI device driver instead,
which actually deals with that buffers.
Add a flag parameter to mhi_prepare_for_transfer allowing to specify
if buffers have to be allocated and queued by the MHI stack.
Keep auto_queue flag for now, but should be removed at some point.

Some versions of the MC firmware wrongly report 0 for register base
address of the DPMCP associated with child DPRC objects thus rendering
them unusable. This is particularly troublesome in ACPI boot scenarios
where the legacy way of extracting this base address from the device
tree does not apply.
Given that DPMCPs share the same base address, workaround this by using
the base address extracted from the root DPRC container.

If the endpoint of a device is not yet probed on the bus, force
a rescan of the devices and retry to get a reference to the
endpoint device. If the device is still not found then we assume
it's in a different isolation context (container/DPRC) thus
unavailable and return a permission error.

Add a bus notifier to pause the MC firmware as soon as its device
gets discovered. This is needed as the firmware is live thus, as soon
as the SMMU gets probed and enabled, it will crash the firmware due to
SMMU context faults. The firmware will be resumed at probe time, after
the required IOMMU setup was completed.

This reverts commit ce78ffa3ef1681065ba451cfd545da6126f5ca88.
Wren and Nicolas reported that ath11k was failing to initialise QCA6390
Wi-Fi 6 device with error:
qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22
Commit ce78ffa3ef16 ("net: really fix the build..."), introduced in
v5.14-rc5, caused this regression in qrtr. Most likely all ath11k
devices are broken, but I only tested QCA6390. Let's revert the broken
commit so that ath11k works again.

Fix for omap gpt12 timer error handling
Two of the recent fixes for ti-sysc driver had bad interaction for a
function return value that caused one of the fixes to not work so we
need to change the return value handling. Otherwise early beagleboard
variants still have a boot issue.
