Quite some controller drivers use the defines from the internal header
already. This prevents controller drivers outside the mailbox directory.
Move the defines to the public controller header to allow this again as
the defines are not strictly internal anyhow.

Memory resources are optional but if the resource is empty
devm_platform_get_and_ioremap_resource() prints an error nonetheless.
Refactor the code to check the resources locally first and process them
only if they are present. The -EBUSY error message of ioremap_resource()
is still kept because it is correct. The comment which explains that a
plain ioremap() is tried as a workaround is turned into a info message.
So, a user will be informed about it, too.

Usual mixed back of ancient issues surfacing and newer problems.
adi,ad57770r
- Stop eating an error in read_raw.
adi,adxl313
- Check return of regmap_write() instead of ignoring it in one place.
adi,adxl355
- Fix the description of the temperature channel to be unsigned rather
than signed.
bosch,bmi160
- Avoid use of uninitialized data.
- Fix validation of small reference voltages.
hid-sensor-rotation:
- The timestamp location in this driver has unfortunately been broken for
a long time. Given it was correct for 6 years and then broken for the
next 6 years, use a one off hack to duplicate it in both locations.
The issue was as a result of the unique nature of quaternion
representation combined with large precision resulting in an
128 bit aligned channel.

Add support for timer by reusing existing sun4i timer driver.
H616 timer is compatible with earlier sunxi timer variants and provides
both clocksource and clockevent functionality. It runs from 24 MHz
oscillator. It can serve as broadcast clockevent for wake up from idle
states.
Tested on Orange Pi Zero 3:
- timer is registered as clocksource:
- switching clocksource at runtime works
- timer operates as a broadcast clockevent device
- no regression observed compared to arch_sys_counter

Usual mixed bag of fixes for recent code and much older issues that have
surfaced. Biggest group are continued resolution of IRQF_ONE_SHOT
being used incorrectly (which now triggers a warning)
adi,ad4062
- Replace IRQF_ONESHOT (as no threaded handler) with IRQF_NO_THREAD as
the caller makes use of iio_trigger_poll() which cannot run from a
thread.
adi,ade9000
- Move mutex_init() earlier to ensure it is available if spurious IRQ
occurs.
adi,adis16550
- Fix swapped gyro and accel filter functions.
adi,adxl3380
- Fix some bit manipulation that was always resulting in 0.
- Fix incorrect register map for calibbias on the active power channel.
- Fix returning IRQF_HANDLED from a function that should return 0 or
-ERRNO.
aspeed,adc
- Clear a reference voltage bit that might be set prior to driver load.
bosch,bno055
- Off by one channel buffer sizing. Benine due to padding prior to the
subsequent timestamp.
hid-sensors
- A more complex fix to IRQF_ONESHOT warning as this driver had a trigger
that was never actually used but the ABI that exposed had to be
maintained to avoid regressions.
hid-sensors-rotation
- An obscure buffer alignment case that applies to quaternions only was
recently broken resulting in writes beyond the end of the channel buffer.
Add a new core macro and apply it in this driver to make it very clear
what was going on.
honeywell,abp2030pa
- Remove meaningless IRQF_ONESHOT from a non threaded IRQ handler.
Warning fix only.
invense,mpu3050
- Fix token passed to free_irq() to match the one used at setup.
- Fix an irq resource leak in error path.
- Reorder probe so that userspace interfaces are exposed only after
everything else has finished.
- Reorder remove slightly to cleanup the buffer only after irq removed
ensuring reverse of probe sequence.
microchip,mcp47feb02
- Fix use of mutex before it was initialized by not performing unnecessary
lock that was early enough in probe that all code was serial.
st,lsm6dsx
- Ensure that FIFO ODR is only controllable for accel and gyro channels
avoiding incorrect register accesses.
- Restrict separation of buffer sampling from main sampling rate to
accelerometer. It is only useful for running event detection faster
than the fifo and the only events are on the accelerometer.
ti,ads1018
- Fix overflow of u8 which wasn't big enough to store max data rate value.
ti,ads1119:
- Fix unbalanced pm in an error path.
- IRQF_ONESHOT (as no threaded handler) replaced with IRQF_NO_THREAD

After SNP_SHUTDOWN, two things should be done:
1. clear the RMP table
2. disable MFDM to prevent the FW_WARN in k8_check_syscfg_dram_mod_en() in
the event of a kexec
Create and export to the CCP driver a function that does them.
Also change the MFDM helper to allow for disabling the bit, since the SNP x86
shutdown path needs to disable MFDM.

Commit ab949d5196 ("ALSA: hda - Fix deadlock of controller device
lock at unbinding") added a temporary device_unlock()/device_lock()
pair around probe-work cancellation to avoid a deadlock between
controller unbind and codec probe.
That deadlock depended on the driver core taking both a device lock and
its parent lock during bind and unbind. Since commit 8c97a46af0
("driver core: hold dev's parent lock when needed") and follow-up
fixes, the parent lock is only taken when bus->need_parent_lock is set.
The HDA bus does not set that flag, so codec binding no longer locks
the controller device as the codec's parent.
Keep cancel_delayed_work_sync(), since the async probe/remove race
still needs to be serialized, but drop the stale unlock/relock
workaround and its outdated FIXME comment. Keeping it around only
opens an unnecessary unlocked window inside azx_remove().

In preparation for delayed SNP initialization, create a function snp_prepare()
that does the necessary architecture setup. Export this function for the ccp
module to allow it to do the setup as necessary.
Introduce a cpu_read_lock/unlock() wrapper around the MFDM and SNP enable.
While CPU hotplug is not supported, this makes sure that the bit setting
happens on the same set of CPUs in both cases.

The nVHE world-switch code relies on zeroing PMSCR_EL1 to disable
profiling data generation in guest context when SPE is in use by the
host.
Unfortunately, this may leave PMBLIMITR_EL1.E set and consequently we
can end up running in guest/hypervisor context with the Profiling Buffer
enabled. The current "known issues" document for Rev M.a of the Arm ARM
states that this can lead to speculative, out-of-context translations:
| 2.18 D23136:
|
| When the Profiling Buffer is enabled, profiling is not stopped, and
| Discard mode is not enabled, the Statistical Profiling Unit might
| cause speculative translations for the owning translation regime,
| including when the owning translation regime is out-of-context.
In a similar fashion to TRBE, ensure that the Profiling Buffer is
disabled during the nVHE world switch before we start messing with the
stage-2 MMU and trap configuration.

The nVHE world-switch code relies on zeroing TRFCR_EL1 to disable trace
generation in guest context when self-hosted TRBE is in use by the host.
Per D3.2.1 ("Controls to prohibit trace at Exception levels"), clearing
TRFCR_EL1 means that trace generation is prohibited at EL1 and EL0 but
per R_YCHKJ the Trace Buffer Unit will still be enabled if
TRBLIMITR_EL1.E is set. R_SJFRQ goes on to state that, when enabled, the
Trace Buffer Unit can perform address translation for the "owning
exception level" even when it is out of context.
Consequently, we can end up in a state where TRBE performs speculative
page-table walks for a host VA/IPA in guest/hypervisor context depending
on the value of MDCR_EL2.E2TB, which changes over world-switch. The
potential result appears to be a heady mixture of SErrors, data
corruption and hardware lockups.
Extend the TRBE world-switch code to clear TRBLIMITR_EL1.E after
draining the buffer, restoring the register on return to the host. This
unfortunately means we need to tackle CPU errata #2064142 and #2038923
which add additional synchronisation requirements around manipulations
of the limit register. Hopefully this doesn't need to be fast.

- Fix potential deadlock in osnoise and hotplug
The interface_lock can be called by a osnoise thread and the CPU shutdown
logic of osnoise can wait for this thread to finish. But cpus_read_lock()
can also be taken while holding the interface_lock. This produces a
circular lock dependency and can cause a deadlock.
Swap the ordering of cpus_read_lock() and the interface_lock to have
interface_lock taken within the cpus_read_lock() context to prevent this
circular dependency.
- Fix freeing of event triggers in early boot up
If the same trigger is added on the kernel command line, the second
one will fail to be applied and the trigger created will be freed.
This calls into the deferred logic and creates a kernel thread to do
the freeing. But the command line logic is called before kernel
threads can be created and this leads to a NULL pointer dereference.
Delay freeing event triggers until late init.

The function tracing_alloc_snapshot() is only used between trace.c and
trace_snapshot.c. When snapshot isn't configured, it's not used at all.
The stub function was defined as a global with no users and no prototype
causing build issues.
Remove the function when snapshot isn't configured as nothing is calling
it.
Also remove the EXPORT_SYMBOL_GPL() that was associated with it as it's
not used outside of the tracing subsystem which also includes any modules.

Replace the nova-core local `DmaObject` with a `CoherentBox` that can
fulfill the same role.
Since `CoherentBox` is more flexible than `DmaObject`, we can use the
native `u64` type for page table entries instead of messing with bytes.
The `dma` module becomes unused with that change, so remove it as well.

A very common pattern is to create a block of coherent memory with the
content of an already-existing slice of bytes (e.g. a loaded firmware
blob).
`CoherentBox` makes this easier, but still implies a potentially
panicking operation with `copy_from_slice` that requires a `PANIC`
comment.
Add `from_slice_with_attrs` and `from_slice` methods to both `Coherent`
and `CoherentBox` to turn this into a trivial one-step operation.

print_gpio() prints the GPIO capability header and the bidirectional
GPIO state, but it never reports the separate GPI and GPO pins even
though AC_PAR_GPIO_CAP exposes their counts.
The HD-audio specification defines dedicated GPI and GPO verbs
alongside the GPIO ones, so codecs with input-only or output-only
general-purpose pins currently lose that state from
/proc/asound/card*/codec#* altogether.
Add the missing read verb definitions and extend print_gpio() to dump
the GPI and GPO pins, too, while leaving the existing IO[] output
unchanged.
