Pull SoC driver updates from Arnd Bergmann:
"Changes are all over the place, but very little sticks out as
noteworthy.
There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
I/O chip, along with hooking it up to the pinctrl and clk frameworks.
The reset controller and memory subsystems have mainly small updates,
but there are two new reset drivers for the K230 and VC1800B SoCs, and
new memory driver support for Tegra264.
The ARM SMCCC and SCMI firmware drivers gain a few more features that
should help them be supported across more environments. Similarly, the
SoC specific firmware on Tegra and Qualcomm get minor enhancements and
chip support.
In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
grow to support more chips, while the Hisilicon, Mediatek and Renesas
drivers see mostly janitorial fixes"

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().
So use the dev_fwnode() helper.

When a remote device sends a completion event to the host, it contains a
pointer to the consumed TRE. The host uses this pointer to process all of
the TREs between it and the host's local copy of the ring's read pointer.
This works when processing completion for chained transactions, but can
lead to nasty results if the device sends an event for a single-element
transaction with a read pointer that is multiple elements ahead of the
host's read pointer.
For instance, if the host accesses an event ring while the device is
updating it, the pointer inside of the event might still point to an old
TRE. If the host uses the channel's xfer_cb() to directly free the buffer
pointed to by the TRE, the buffer will be double-freed.
This behavior was observed on an ep that used upstream EP stack without
'commit 6f18d174b73d ("bus: mhi: ep: Update read pointer only after buffer
is written")'. Where the device updated the events ring pointer before
updating the event contents, so it left a window where the host was able to
access the stale data the event pointed to, before the device had the
chance to update them. The usual pattern was that the host received an
event pointing to a TRE that is not immediately after the last processed
one, so it got treated as if it was a chained transaction, processing all
of the TREs in between the two read pointers.
This commit aims to harden the host by ensuring transactions where the
event points to a TRE that isn't local_rp + 1 are chained.

On big endian platform like PowerPC, the MHI bus (which is little endian)
does not start properly. The following example shows the error messages by
using QCN9274 WLAN device with ath12k driver:

ath12k_pci: probe of 0001:01:00.0 failed with error -110
The issue seems to be with the incorrect DMA address/size used for
transferring the firmware image over BHI. So fix it by converting the DMA
address and size of the BHI vector table to little endian format before
sending them to the device.

devm_of_platform_populate() passes a NULL as the bus OF match table
to the underlying of_platform_populate(), meaning child bus devices
of the AIPSTZ bridge will not have its children devices created. Since
some SoCs (e.g. i.MX8MP) use this particular setup (e.g. SPBA bus, which
is a child of AIPSTZ5 and has multiple child nodes), the driver needs to
support it.
Therefore, replace devm_of_platform_populate() with of_platform_populate()
and pass a reference to the bus OF match table to it. For now, the only
possible child buses are simple buses.
Since the usage of devres is dropped, the complementary operation of
of_platform_populate() needs to be called during the driver's removal.

The secure AHB to IP Slave (AIPSTZ) bus bridge provides access control
configurations meant to restrict access to certain peripherals.
Some of the configurations include:
1) Marking masters as trusted for R/W. Based on this
(and the configuration of the accessed peripheral), the bridge
may choose to abort the R/W transactions issued by certain
masters.
2) Allowing/disallowing write accesses to peripherals.
Add driver for this IP. Since there's currently no framework for
access controllers (and since there's currently no need for having
flexibility w.r.t the configurations) all this driver does is it
applies a relaxed, "default" configuration, in which all masters
are trusted for R/W.
Note that some instances of this IP (e.g: AIPSTZ5 on i.MX8MP) may be tied
to a power domain and may lose their configuration when the domain is
powered off. This is why the configuration has to be restored when the
domain is powered on.

irq_domain_add_simple() is going away as being obsolete now. Switch to
the preferred irq_domain_create_simple(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

When mhi_async_power_up() enables IRQs, it is possible that we could
receive a SYSERR notification from the device if the firmware has crashed
for some reason. Then the SYSERR notification queues a work item that
cannot execute until the pm_mutex is released by mhi_async_power_up().
So the SYSERR work item will be pending. If mhi_async_power_up() detects
the SYSERR, it will handle it. If the device is in PBL, then the PBL state
transition event will be queued, resulting in a work item after the
pending SYSERR work item. Once mhi_async_power_up() releases the pm_mutex,
the SYSERR work item can run. It will blindly attempt to reset the MHI
state machine, which is the recovery action for SYSERR. PBL/SBL are not
interrupt driven and will ignore the MHI Reset unless SYSERR is actively
advertised. This will cause the SYSERR work item to timeout waiting for
reset to be cleared, and will leave the host state in SYSERR processing.
The PBL transition work item will then run, and immediately fail because
SYSERR processing is not a valid state for PBL transition.
This leaves the device uninitialized.
This issue has a fairly unique signature in the kernel log:
mhi mhi3: Requested to power ON
Qualcomm Cloud AI 100 0000:36:00.0: Fatal error received from
device. Attempting to recover
mhi mhi3: Power on setup success
mhi mhi3: Device failed to exit MHI Reset state
mhi mhi3: Device MHI is not in valid state
We cannot remove the SYSERR handling from mhi_async_power_up() because the
device may be in the SYSERR state, but we missed the notification as the
irq was fired before irqs were enabled. We also can't queue the SYSERR work
item from mhi_async_power_up() if SYSERR is detected because that may
result in a duplicate work item, and cause the same issue since the
duplicate item will blindly issue MHI reset even if SYSERR is no longer
active.
Instead, add a check in the SYSERR work item to make sure that MHI reset is
only issued if the device is in SYSERR state for PBL or SBL EEs.

Both destination buffers are already zero-initialized, making strscpy()
sufficient for safely copying 'obj_type'. The additional NUL-padding
performed by strscpy_pad() is unnecessary.
If the destination buffer has a fixed length, strscpy() automatically
determines its size using sizeof() when the argument is omitted. This
makes the explicit size arguments unnecessary.
No functional changes intended.

Since it's not currently safe to take device_lock() in the IOMMU probe
path, that can race against really_probe() setting dev->driver before
attempting to bind. The race itself isn't so bad, since we're only
concerned with dereferencing dev->driver itself anyway, but sadly my
attempt to implement the check with minimal churn leads to a kind of
TOCTOU issue, where dev->driver becomes valid after to_fsl_mc_driver(NULL)
is already computed, and thus the check fails to work as intended.
Will and I both hit this with the platform bus, but the pattern here is
the same, so fix it for correctness too.

The fsl-mc bus associated to the root DPRC in a DPAA2 system exports a
device file for userspace access to the MC firmware. In case the DPRC's
local MC portal (DPMCP) is currently in use, a new DPMCP device is
allocated through the fsl_mc_portal_allocate() function.
In this case, the call to fsl_mc_portal_allocate() will fail with -EINVAL
when trying to add a device link between the root DPRC (consumer) and
the newly allocated DPMCP device (supplier). This is because the DPMCP
is a dependent of the DPRC device (the bus).
Fix this by not adding a device link in case the DPMCP is allocated for
the root DPRC's usage.

The blamed commit tried to simplify how the deallocations are done but,
in the process, introduced a double-free on the mc_dev variable.
In case the MC device is a DPRC, a new mc_bus is allocated and the
mc_dev variable is just a reference to one of its fields. In this
circumstance, on the error path only the mc_bus should be freed.
This commit introduces back the following checkpatch warning which is a
false-positive.

Inside mhi_ep_ring_add_element, the read pointer (rd_offset) is updated
before the buffer is written, potentially causing race conditions where
the host sees an updated read pointer before the buffer is actually
written. Updating rd_offset prematurely can lead to the host accessing
an uninitialized or incomplete element, resulting in data corruption.
Invoke the buffer write before updating rd_offset to ensure the element
is fully written before signaling its availability.

fsl_mc_allocator_driver_exit() was added explicitly by
commit 1e8ac83b6caf ("bus: fsl-mc: add fsl_mc_allocator cleanup function")
but was never used.
Remove it.
fsl_mc_portal_reset() was added in 2015 by
commit 197f4d6a4a00 ("staging: fsl-mc: fsl-mc object allocator driver")
but was never used.
Remove it.
fsl_mc_portal_reset() was the only caller of dpmcp_reset().
Remove it.
