The PLL lock failure path in adau1372_set_power() unwinds by putting
the regmap back in cache-only mode, asserting the optional power-down
GPIO and disabling mclk.
adau1372_enable_pll() enables CLK_CTRL.PLL_EN before polling the PLL
lock bit. If the lock fails on a board without a power-down GPIO, the
error path disables mclk and returns an error, but leaves PLL_EN set in
the hardware register. The normal power-off path already handles the
no-GPIO case by explicitly clearing PLL_EN.
Mirror that cleanup in the PLL lock failure path and clear PLL_EN while
the regmap is still live, before switching it back to cache-only mode.

Add an explicit dependency between the output object files and the
output directories that need to be created to hold those files. This
ensures that the output directories are always created.
Creating the output directories at parse time (current behavior) doesn't
support the scenario where someone does "make clean all". The
directories will be created during parsing, deleted during "clean" and
then not available for the "all" target.
Use an order-only prerequisite for the output directories, rather than a
normal prerequisite, to avoid unnecessary recompilations.

Any invalid endpoint decoder pointer in the target array of an active
region is not allowed by cxl driver. This means cxl driver always
assumes the first p->nr_targets entries of the target array in an
auto-assembly region are valid. However, there are scenarios that could
leave NULL endpoint decoder pointer holes in the target array.
1. When cxl_cancel_auto_attach() removes an endpoint decoder from a
target array, the target slot is set to NULL. If the removed endpoint
decoder is not the last element in the target array, the target array
will contain a NULL hole.
2. When a auto-assembly region removes an assigned endpoint decoder, if
the removed endpoint decoder is not the last element in the target
array, always remains a NULL hole in the target array.
When a NULL pointer hole exists in a region's target array, it
introduces two potential problems:
1. Access an endpoint decoder via a NULL pointer. it always trigger
calltrace like that.

2. Not having enough valid endpoint decoders attached to an
auto-assembly region. if an auto-assembly region is created with lock
flag or assigned endpoint decoder with lock flag, which means
assigned endpoint decoder will not be reset during detaching, they
could re-attach to the auto-assembly region again. But cxl region
driver relies on p->nr_targets to verify whether the required number
of endpoint decoders has been attached, and NULL endpoint decoder
pointers are still counted in that case.
To fix above issues, adjust cxl_region_attach_auto() logic to find the
first free target slot for endpoint decoder attachment, this ensures
NULL holes in the target array are filled, rather than adding new
endpoint decoders at the tail of the target array.

In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for
accessing p->targets[]. However, cxled->pos can be set to negative errno
in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This
causes the driver to use a negative index to access p->targets[],
resulting in out-of-bounds access.
Fix it by walking p->targets[] instead of using cxled->pos directly.

The error bouncing may fail again, and we have no check for
re-bouncing. For avoiding the loop, add the event type check at
bouncing, and stop re-bouncing if it's already a bounce error.

So far our parsing of {iommu,msi}-map properties has always blindly
assumed that the output specifiers will always have exactly 1 cell.
This typically does happen to be the case, but is not actually enforced
(and the PCI msi-map binding even explicitly states support for 0 or 1
cells) - as a result we've now ended up with dodgy DTs out in the field
which depend on this behaviour to map a 1-cell specifier for a 2-cell
provider, despite that being bogus per the bindings themselves.
Since there is some potential use in being able to map at least single
input IDs to multi-cell output specifiers (and properly support 0-cell
outputs as well), add support for properly parsing and using the target
nodes' #cells values, albeit with the unfortunate complication of still
having to work around expectations of the old behaviour too.
Since there are multi-cell output specifiers, the callers of of_map_id()
may need to get the exact cell output value for further processing.
Update of_map_id() to set args_count in the output to reflect the actual
number of output specifier cells.

Change of_map_id() to take a pointer to struct of_phandle_args
instead of passing target device node and translated IDs separately.
Update all callers accordingly.
Add an explicit filter_np parameter to of_map_id() and of_map_msi_id()
to separate the filter input from the output. Previously, the target
parameter served dual purpose: as an input filter (if non-NULL, only
match entries targeting that node) and as an output (receiving the
matched node with a reference held). Now filter_np is the explicit
input filter and arg->np is the pure output.
Previously, of_map_id() would call of_node_put() on the matched node
when a filter was provided, making reference ownership inconsistent.
Remove this internal of_node_put() call so that of_map_id() now always
transfers ownership of the matched node reference to the caller via
arg->np. Callers are now consistently responsible for releasing this
reference with of_node_put(arg->np) when done.

Since we now have quite a few users parsing "iommu-map" and "msi-map"
properties, give them some wrappers to conveniently encapsulate the
appropriate sets of property names. This will also make it easier to
then change of_map_id() to correctly account for specifier cells.

The mock auto-region created at module load wrote switch and host-bridge
decoder target[] directly, in addition to target_map[]. Real HW programs
only target_map[] and resolves target[] as dports enumerate, via
update_decoder_targets(). Region replay already follows that ordering,
the initial auto-region did not.
Drop the direct target[] writes and call
cxl_port_update_decoder_targets() so target[] is resolved the same way
as real HW and region replay, exercising more of the auto-region driver
path.

commit 87a3f5c8ac ("ASoC: sdw_utils: cs42l43: allow spk component names
to be combined") moved spk:cs42l43-spk generation from rtd_init() into
the asoc_sdw_rtd_init() generic path by adding component_name to
codec_info_list entries. However, only the 0x4243 cs42l43 entry was
updated; the 0x2A3B entry (vendor_id 0x01fa, Cirrus Logic cs42l43 with
sidecar bridge) was missed.
Without component_name on the 0x2A3B dp6 DAI, asoc_sdw_rtd_init() never
accumulates spk_components and never appends 'spk:cs42l43-spk' (or its
sidecar alias 'spk:cs35l56-bridge') to card->components. The sof-soundwire
UCM regex ' spk:([a-z0-9]+...)' then fails to match, causing WirePlumber
to mark all HiFi profiles as unavailable=no and fall back to the Off
profile — resulting in Dummy Output in GNOME.
The existing sidecar redirect in asoc_sdw_rtd_init() already handles the
SOC_SDW_SIDECAR_AMPS case: when component_name is 'cs42l43-spk' and
sidecar amps are active, it substitutes 'cs35l56-bridge' into
card->components, which matches the existing cs35l56-bridge.conf UCM file.

The interleave conversion helpers translate between encoded HDM
interleave values and the granularity and way values used by the
driver.
These helpers have been a recurring source of static analysis
complaints that expose type mismatches and potentially uninitialized
outputs. Fix those issues in the helpers so callers inherit the
consistent behavior automatically.
The decode and encode helpers have different interface issues.
The decode helpers return values through unsigned int pointers, but
the decoded values are ultimately represented as int throughout the
driver. Align the helper interfaces with their callers by changing
the out-parameters to int * and updating the handful of affected
locals to match.
The encode helpers leave their out-parameters unchanged on error. That
means callers that ignore the return value may observe uninitialized
encoded values. Initialize the outputs so failed conversions leave
defined values. This issue was originally reported by Purva and the
helper-side fix was suggested by Dan [1].
Tidy up a related, pre-existing, printk format specifier mismatch in
cxl_validate_translation_params().
No functional change for valid interleave parameters.

iommu_copy_struct_from_full_user_array() copies a whole user array into a
kernel buffer. In the common case, where user entry_len equals destination
entry size, it takes a fast path and copies the whole array with a single
copy_from_user().
That fast path does not return, so it falls through into the item-by-item
copy_struct_from_user() loop and copies every entry a second time. For an
equal entry_len that loop is just a copy_from_user() of the same bytes, so
the whole array is copied twice for no benefit.
Return right after the bulk copy. The per-item loop then runs only on the
slow path, where entry_len differs and each entry needs size adaption.

iommufd_hwpt_invalidate() takes a user-controlled entry_num and entry_len,
each bounded only by U32_MAX. An entry_len beyond the kernel's struct size
makes the copy helper verify the extra bytes are zero, scanning that excess
in one uninterruptible pass; a multi-gigabyte value over zeroed user memory
trips the soft-lockup watchdog.
A large entry_num is the other half, driving the backend invalidation loop
with no reschedule. The VT-d nested handler, for one, copies each entry and
flushes caches per iteration, pinning the CPU on a non-preemptible kernel.
Cap both in the ioctl. entry_len is held under PAGE_SIZE, above any request
struct, and entry_num under 1 << 19, the order of a hardware invalidation
queue and well beyond any real batch, bounding the per-call loop length.

The method the driver uses to determine the size of the FIFO has a
problem. What it currently does is this:
It stops the SPI hardware and writes to the TX FIFO register until TX
FIFO FULL asserts in the status register. But the hardware does not only
have the FIFO, it also has a shift register which can hold a byte. This
can be seen, when writing a byte to the FIFO (while the SPI hardware is
stopped,) the TX FIFO EMPTY is still empty. So, if we have a FIFO size
of 16 for example, the current method returns a 17.
This is a problem, at least when using the driver in irq mode. The same
size determined for the TX FIFO is also assumed for the RX FIFO. When a
SPI transaction wants to write the amount of the FIFO size or more
bytes, the following happens, for example with 16 bytes FIFO size:
The driver stops the SPI hardware and writes 17 bytes to the TX FIFO and
starts the SPI hardware and goes sleep.
The hardware then shifts out 17 bytes (FIFO + shift register) and
simultaneously reads bytes into the RX FIFO, but it only has 16 places,
so it looses one byte. Then TX FIFO empty asserts, wakes the driver
again, which has a fast path and reads 16 bytes from the RX FIFO, but
before reading the last 17th byte (which is lost) it does this:
sr = xspi->read_fn(xspi->regs + XSPI_SR_OFFSET);
if (!(sr & XSPI_SR_RX_EMPTY_MASK)) {
xilinx_spi_rx(xspi);
rx_words--;
}
It reads the status register and checks if the RX FIFO is not empty.
But it is empty in our case. So this check spins in a while loop
forever locking the driver.
This patch fixes the logic to determine the FIFO size.
