[ Upstream commit 794ef0e57854d794173c8ab6bcce3285032dcd95 ]
Move to the IIO backend framework. Devices supported by adi-axi-adc now
register themselves as backend devices.

[ Upstream commit bb42191f85c389bf816373d25c3e4c94045cf4ff ]
Convert the driver to use the new IIO backend framework. The device
functionality is expected to be the same (meaning no added or removed
features).
Also note this patch effectively breaks ABI and that's needed so we can
properly support this device and add needed features making use of the
new IIO framework.
Given the lack of features (and devices supported) in the ad9467 driver
compared with the ADI out of tree version, we don't expect any user of
the upstream driver so no one should notice the ABI breakage. However,
if someone is affected by this, ADI will happily support transitioning
to the backend framework.

[ Upstream commit 1a97905d3e48ebe79a06d16143fbfa427c56ce5f ]
This is a Framework to handle complex IIO aggregate devices.
The typical architecture is to have one device as the frontend device which
can be "linked" against one or multiple backend devices. All the IIO and
userspace interface is expected to be registers/managed by the frontend
device which will callback into the backends when needed (to get/set
some configuration that it does not directly control).
The basic framework interface is pretty simple:
- Backends should register themselves with @devm_iio_backend_register()
- Frontend devices should get backends with @devm_iio_backend_get()

Export iio_dmaengine_buffer_free() and iio_dmaengine_buffer_alloc().
This is in preparation of introducing IIO backends support. This will
allow us to allocate a buffer and control it's lifetime from a device
different from the one holding the DMA firmware properties. Effectively,
in this case the struct device holding the firmware information about
the DMA channels is not the same as iio_dev->dev.parent (typical case).
While at it, namespace the buffer-dmaengine exports and update the
current user of these buffers.

These tests record in a mode that includes kernel trace but look for
samples of a userspace process. This makes them sensitive to any kernel
compilation options that increase the amount of time spent in the
kernel. If the trace buffer is completely filled before userspace is
reached then the test will fail. Double the buffer size to fix this.
The other tests in the same file aren't sensitive to this for various
reasons, for example the iterate devices test filters by userspace trace
only. But in order to keep coverage of all the modes, increase the
buffer size rather than filtering by userspace for the basic tests.

'perf test' needs to update base-record & system-wide-dummy attr expected values
for test-record-C0:
1. Because a dummy sideband event is added to the sampling of specified
CPUs. When evlist contains evsel of different sample_type,
evlist__config() will change the default PERF_SAMPLE_ID bit to
PERF_SAMPLE_IDENTIFICATION bit.
The attr sample_type expected value of base-record and system-wide-dummy
in test-record-C0 needs to be updated.
2. The perf record uses evlist__add_aux_dummy() instead of
evlist__add_dummy() to add a dummy event.
The expected value of system-wide-dummy attr needs to be updated.
The 'perf test' result is as follows:
# ./perf test list 2>&1 | grep 'Setup struct perf_event_attr'
17: Setup struct perf_event_attr
# ./perf test 17
17: Setup struct perf_event_attr : Ok

PERF_PMU_CAP_EXTENDED_HW_TYPE results in multiple events being opened on
heterogeneous systems. Currently this test only sets its required
attributes on the first event. Not disabling enable_on_exec on the other
events causes the test to fail because the forked objdump processes are
sampled. No tracking event is opened so Perf only knows about its own
mappings causing the objdump samples to give the following error:

To prevent anyone from seeing a test failure appear as a regression and
thinking that it was caused by their code change, insert some noise into
the loop which makes it immune to sampling bias issues (errata 1694299).
The "test data symbol" test can fail with any unrelated change that
shifts the loop into an unfortunate position in the Perf binary which is
almost impossible to debug as the root cause of the test failure.
Ultimately it's caused by the referenced errata.

with map__rip_2objdump() as the second argument but later it's changed
to use notes->start. It's ok in normal cases but it can be changed when
annotate_opts.full_addr is set. So let's convert the address directly
instead of using the notes->start.
Also the last argument is an IP to print symbol offset if requested. So

'struct thread' values hold onto references to mmaps, DSOs, etc. When a
thread exits it is necessary to clean all of this memory up by removing
the thread from the machine's threads. Some tools require this doesn't
happen, such as auxtrace events, 'perf report' if offcpu events exist or
if a task list is being generated, so add a 'struct symbol_conf' member
to make the behavior optional. When an exited thread is left in the
machine's threads, mark it as exited.
This change relates to commit 40826c45eb0b8856 ("perf thread: Remove
notion of dead threads") . Dead threads were removed as they had a
reference count of 0 and were difficult to reason about with the
reference count checker. Here a thread is removed from threads when it
exits, unless via symbol_conf the exited thread isn't remove and is
marked as exited. Reference counting behaves as it normally does.

dmi_class uses kfree() as the .release function, but that now causes
a warning with clang-16 as it violates control flow integrity (KCFI)
rules:
drivers/firmware/dmi-id.c:174:17: error: cast from 'void (*)(const void *)' to 'void (*)(struct device *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
174 | .dev_release = (void(*)(struct device *)) kfree,
Add an explicit function to call kfree() instead.

For some reason, we add an offset to the PDI, presumably to skip the
PDI0 and PDI1 which are reserved for BPT.
This code is however completely wrong and leads to an out-of-bounds
access. We were just lucky so far since we used only a couple of PDIs
and remained within the PDI array bounds.
A Fixes: tag is not provided since there are no known platforms where
the out-of-bounds would be accessed, and the initial code had problems
as well.
A follow-up patch completely removes this useless offset.

In a way similar to the previous commit, move
typec_partner_set_usb_power_delivery() to be called after reading the PD
caps. This also removes calls to
usb_power_delivery_unregister_capabilities() from the error path. Keep
all capabilities registered until they are cleared by
ucsi_unregister_partner_pdos().

UCSI driver will attempt to set a USB PD device only if it was able to
read PDOs from the firmware. This results in suboptimal behaviour, since
the PD device will be created anyway. Move calls to
typec_port_set_usb_power_delivery() out of conditional code and call it
after reading capabilities.
