The devm_add_action_or_reset() function already executes the cleanup
action on failure before returning an error, so the explicit goto error
and subsequent zl3073x_dev_dpll_fini() call causes double cleanup.

The REF_PHASE_OFFSET_COMP register is 48-bit wide on most zl3073x chip
variants, but only 32-bit wide on chip IDs 0x0E30, 0x0E93..0x0E97 and
0x1F60. The driver unconditionally uses 48-bit read/write operations,
which on 32-bit variants causes reading 2 bytes past the register
boundary (corrupting the value) and writing 2 bytes into the adjacent
register.
Fix this by storing the chip ID in the device structure during probe
and adding a helper to detect the affected variants. Use the correct
register width for read/write operations and the matching sign extension
bit (31 vs 47) when interpreting the phase compensation value.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The frequency for an input reference is computed as:
frequency = freq_base * freq_mult * freq_ratio_m / freq_ratio_n
Before commit 5bc02b190a3fb ("dpll: zl3073x: Cache all reference
properties in zl3073x_ref"), zl3073x_dpll_input_pin_frequency_set()
explicitly wrote 1 to both the REF_RATIO_M and REF_RATIO_N hardware
registers whenever a new frequency was set. This ensured the FEC ratio
was always reset to 1:1 alongside the new base/multiplier values.
The refactoring in that commit introduced zl3073x_ref_freq_set() to
update the cached ref state, but this helper only sets freq_base and
freq_mult without resetting freq_ratio_m and freq_ratio_n to 1. Because
zl3073x_ref_state_set() uses a compare-and-write strategy, unchanged
ratio fields are never written to the hardware. If the device previously
had non-unity FEC ratio values, they remain in effect after a frequency
change, resulting in an incorrect computed frequency.
Explicitly set freq_ratio_m and freq_ratio_n to 1 in zl3073x_ref_freq_set()
to restore the original behavior.

Ensure the current pin frequency is always present in the list of
supported frequencies reported to userspace. Previously, if the
firmware node was missing or didn't include the current operating
frequency in the supported-frequencies-hz property, the pin would
report a frequency that wasn't in its supported list.
Get the current frequency early in zl3073x_pin_props_get():
- For input pins: use zl3073x_dev_ref_freq_get()
- For output pins: use zl3073x_dev_output_pin_freq_get()
Place the current frequency at index 0 of the supported frequencies
array, then append frequencies from the firmware node (if present),
skipping any duplicate of the current frequency.

Introduce zl3073x_dev_output_pin_freq_get() helper function to compute
the output pin frequency based on synthesizer frequency, output divisor,
and signal format. For N-div signal formats, the N-pin frequency is
additionally divided by esync_n_period.
Add zl3073x_out_is_ndiv() helper to check if an output is configured
in N-div mode (2_NDIV or 2_NDIV_INV signal formats).
Refactor zl3073x_dpll_output_pin_frequency_get() callback to use the
new helper, reducing code duplication and enabling reuse of the
frequency calculation logic in other contexts.
This is a preparatory change for adding current frequency to the
supported frequencies list in pin properties.

The output pin phase adjustment functions incorrectly negate the phase
compensation value.
Per the ZL3073x datasheet, the output phase compensation register is
simply a signed two's complement integer where:
- Positive values move the phase later in time
- Negative values move the phase earlier in time
No negation is required. The erroneous negation caused phase adjustments
to be applied in the wrong direction.
Note that input pin phase adjustment correctly uses negation because the
hardware has an inverted convention for input references (positive moves
phase earlier, negative moves phase later).

Update existing DPLL drivers to utilize the DPLL reference count
tracking infrastructure.
Add dpll_tracker fields to the drivers' internal device and pin
structures. Pass pointers to these trackers when calling
dpll_device_get/put() and dpll_pin_get/put().
This allows developers to inspect the specific references held by this
driver via debugfs when CONFIG_DPLL_REFCNT_TRACKER is enabled, aiding
in the debugging of resource leaks.

Add support for the REF_TRACKER infrastructure to the DPLL subsystem.
When enabled, this allows developers to track and debug reference counting
leaks or imbalances for dpll_device and dpll_pin objects. It records stack
traces for every get/put operation and exposes this information via
debugfs at:
/sys/kernel/debug/ref_tracker/dpll_device_*
/sys/kernel/debug/ref_tracker/dpll_pin_*
The following API changes are made to support this:
1. dpll_device_get() / dpll_device_put() now accept a 'dpll_tracker *'
(which is a typedef to 'struct ref_tracker *' when enabled, or an empty
struct otherwise).
2. dpll_pin_get() / dpll_pin_put() and fwnode_dpll_pin_find() similarly
accept the tracker argument.
3. Internal registration structures now hold a tracker to associate the
reference held by the registration with the specific owner.
All existing in-tree drivers (ice, mlx5, ptp_ocp, zl3073x) are updated
to pass NULL for the new tracker argument, maintaining current behavior
while enabling future debugging capabilities.

Refactor the reference counting mechanism for DPLL devices and pins to
improve consistency and prevent potential lifetime issues.
Introduce internal helpers __dpll_{device,pin}_{hold,put}() to
centralize reference management.
Update the internal XArray reference helpers (dpll_xa_ref_*) to
automatically grab a reference to the target object when it is added to
a list, and release it when removed. This ensures that objects linked
internally (e.g., pins referenced by parent pins) are properly kept
alive without relying on the caller to manually manage the count.
Consequently, remove the now redundant manual `refcount_inc/dec` calls
in dpll_pin_on_pin_{,un}register()`, as ownership is now correctly handled
by the dpll_xa_ref_* functions.
Additionally, ensure that dpll_device_{,un}register()` takes/releases
a reference to the device, ensuring the device object remains valid for
the duration of its registration.

Allow drivers to register DPLL pins without manually specifying a pin
index.
Currently, drivers must provide a unique pin index when calling
dpll_pin_get(). This works well for hardware-mapped pins but creates
friction for drivers handling virtual pins or those without a strict
hardware indexing scheme.
Introduce DPLL_PIN_IDX_UNSPEC (U32_MAX). When a driver passes this
value as the pin index:
1. The core allocates a unique index using an IDA
2. The allocated index is mapped to a range starting above `INT_MAX`
This separation ensures that dynamically allocated indices never collide
with standard driver-provided hardware indices, which are assumed to be
within the `0` to `INT_MAX` range. The index is automatically freed when
the pin is released in dpll_pin_put().

Currently, the DPLL subsystem reports events (creation, deletion, changes)
to userspace via Netlink. However, there is no mechanism for other kernel
components to be notified of these events directly.
Add a raw notifier chain to the DPLL core protected by dpll_lock. This
allows other kernel subsystems or drivers to register callbacks and
receive notifications when DPLL devices or pins are created, deleted,
or modified.
Define the following:
- Registration helpers: {,un}register_dpll_notifier()
- Event types: DPLL_DEVICE_CREATED, DPLL_PIN_CREATED, etc.
- Context structures: dpll_{device,pin}_notifier_info to pass relevant
data to the listeners.
The notification chain is invoked alongside the existing Netlink event
generation to ensure in-kernel listeners are kept in sync with the
subsystem state.

Currently, the dpll subsystem exports the fractional frequency offset
(FFO) in parts per million (ppm). This granularity is insufficient for
high-precision synchronization scenarios which often require parts per
trillion (ppt) resolution.
Add a new netlink attribute DPLL_A_PIN_FRACTIONAL_FREQUENCY_OFFSET_PPT
to expose the FFO in ppt.
Update the dpll netlink core to expect the driver-provided FFO value
to be in ppt. To maintain backward compatibility with existing userspace
tools, populate the legacy DPLL_A_PIN_FRACTIONAL_FREQUENCY_OFFSET
attribute by dividing the new ppt value by 1,000,000.
Update the zl3073x and mlx5 drivers to provide the FFO value in ppt:
- zl3073x: adjust the fixed-point calculation to produce ppt (10^12)
instead of ppm (10^6).
- mlx5: scale the existing ppm value by 1,000,000.

Modify the internal registration helpers dpll_xa_ref_{dpll,pin}_add()
to reject duplicate registration attempts.
Previously, if a caller attempted to register the same pin multiple
times (with the same ops, priv, and cookie) on the same device, the core
silently increments the reference count and return success. This behavior
is incorrect because if the caller makes these duplicate registrations
then for the first one dpll_pin_registration is allocated and for others
the associated dpll_pin_ref.refcount is incremented. During the first
unregistration the associated dpll_pin_registration is freed and for
others WARN is fired.
Fix this by updating the logic to return `-EEXIST` if a matching
registration is found to enforce a strict "register once" policy.

Add support for .supported_modes_get() and .mode_set() callbacks
to enable switching between manual and automatic modes via netlink.
Implement .supported_modes_get() to report available modes based
on the current hardware configuration:
* manual mode is always supported
* automatic mode is supported unless the dpll channel is configured
in NCO (Numerically Controlled Oscillator) mode
Implement .mode_set() to handle the specific logic required when
transitioning between modes:
1) Transition to manual:
* If a valid reference is currently active, switch the hardware
to ref-lock mode (force lock to that reference).
* If no reference is valid and the DPLL is unlocked, switch to freerun.
* Otherwise, switch to Holdover.
2) Transition to automatic:
* If the currently selected reference pin was previously marked
as non-selectable (likely during a previous manual forcing
operation), restore its priority and selectability in the hardware.
* Switch the hardware to Automatic selection mode.

Currently, the DPLL subsystem assumes that the only supported mode is
the one currently active on the device. When dpll_msg_add_mode_supported()
is called, it relies on ops->mode_get() and reports that single mode
to userspace. This prevents users from discovering other modes the device
might be capable of.
Add a new callback .supported_modes_get() to struct dpll_device_ops. This
allows drivers to populate a bitmap indicating all modes supported by
the hardware.
Update dpll_msg_add_mode_supported() to utilize this new callback:
* if ops->supported_modes_get is defined, use it to retrieve the full
bitmap of supported modes.
* if not defined, fall back to the existing behavior: retrieve
the current mode via ops->mode_get and set the corresponding bit
in the bitmap.
Finally, iterate over the bitmap and add a DPLL_A_MODE_SUPPORTED netlink
attribute for every set bit, accurately reporting the device's capabilities
to userspace.

new fields at once, including zero-divisor checks. Refactor all
dpll "getter" functions in dpll.c to read from this new
cached state instead of performing direct register access.
Introduce a new function, zl3073x_out_state_set(), to handle

modified register values via a single mailbox sequence before
updating the local cache.
Refactor all dpll "setter" functions to modify a local copy of

commit the changes.
This change centralizes all output-related register I/O into

Instead of reading the ZL_REG_REF_MON_STATUS register every time
the reference status is needed, cache this value in the zl3073x_ref
struct.
This is achieved by:
* Adding a mon_status field to struct zl3073x_ref
* Introducing zl3073x_dev_ref_status_update() to read the status for
all references into this new cache field
* Calling this update function from the periodic work handler
* Adding zl3073x_ref_is_status_ok() and zl3073x_dev_ref_is_status_ok()
helpers to check the cached value
* Refactoring all callers in dpll.c to use the new
zl3073x_dev_ref_is_status_ok() helper, removing direct register reads
This change consolidates all status register reads into a single periodic
function and reduces I/O bus traffic in dpll callbacks.

Refactor the zl3073x driver by splitting the logic for input
references, outputs and synthesizers out of the monolithic
core.[ch] files.
Move the logic for each functional block into its own dedicated files:
ref.[ch], out.[ch] and synth.[ch].
Specifically:
- Move state structures (zl3073x_ref, zl3073x_out, zl3073x_synth)
from core.h into their respective new headers
- Move state-fetching functions (..._state_fetch) from core.c to their
new .c files
- Move the zl3073x_ref_freq_factorize helper from core.c to ref.c
- Introduce a new helper layer to decouple the core device logic from
the state-parsing logic:
1. Move the original inline helpers (e.g., zl3073x_ref_is_enabled)
to the new headers (ref.h, etc.) and make them operate on a
const struct ... * pointer.
2. Create new zl3073x_dev_... prefixed functions in core.h
(e.g., zl3073x_dev_ref_is_enabled) and Implement these _dev_ functions
to fetch state using a new ..._state_get() helper and then call
the non-prefixed helper.
3. Update all driver-internal callers (in dpll.c, prop.c, etc.) to use
the new zl3073x_dev_... functions.

Currently, the signal format of an associated output is not considered

a given output pin should be registered or not.

The device-id-get and pin-id-get handlers were ignoring errors from
the find functions and sending empty replies instead of returning
error codes to userspace.
When dpll_device_find_from_nlattr() or dpll_pin_find_from_nlattr()
returned an error (e.g., -EINVAL for "multiple matches" or -ENODEV
for "not found"), the handlers checked `if (!IS_ERR(ptr))` and
skipped adding the device/pin handle to the message, but then still
sent the empty message as a successful reply.
This caused userspace tools to receive empty responses with id=0
instead of proper netlink errors with extack messages like
"multiple matches".
The bug is visible via strace, which shows the kernel sending TWO
netlink messages in response to a single request:
1. Empty reply (20 bytes, just header, no attributes):
recvfrom(3, [{nlmsg_len=20, nlmsg_type=dpll, nlmsg_flags=0, ...},
{cmd=0x7, version=1}], ...)
2. NLMSG_ERROR ACK with extack (because of NLM_F_ACK flag):
recvfrom(3, [{nlmsg_len=60, nlmsg_type=NLMSG_ERROR,
nlmsg_flags=NLM_F_CAPPED|NLM_F_ACK_TLVS, ...},
[{error=0, msg={...}},
[{nla_type=NLMSGERR_ATTR_MSG}, "multiple matches"]]], ...)
The C YNL library parses the first message, sees an empty response,
and creates a result object with calloc() which zero-initializes all
fields, resulting in id=0.
The Python YNL library parses both messages and displays the extack
from the second NLMSG_ERROR message.
Fix by checking `if (IS_ERR(ptr))` first and returning the error
code immediately, so that netlink properly sends only NLMSG_ERROR with
the extack message to userspace. After this fix, both C and Python
YNL tools receive only the NLMSG_ERROR and behave consistently.
This affects:
- DPLL_CMD_DEVICE_ID_GET: now properly returns error when multiple
devices match the criteria (e.g., same module-name + clock-id)
- DPLL_CMD_PIN_ID_GET: now properly returns error when multiple pins
match the criteria (e.g., same module-name)
Before fix:
$ dpll pin id-get module-name ice
0 (wrong - should be error, there are 17 pins with module-name "ice")
After fix:
$ dpll pin id-get module-name ice
Error: multiple matches
(correct - kernel reports the ambiguity via extack)

If the internal flash contains missing or corrupted configuration,
basic communication over the bus still functions, but the device
is not capable of normal operation (for example, using mailboxes).
This condition is indicated in the info register by the ready bit.
If this bit is cleared, the probe procedure times out while fetching
the device state.
Handle this case by checking the ready bit value in zl3073x_dev_start()
and skipping DPLL device and pin registration if it is cleared.
Do not report this condition as an error, allowing the devlink device
to be registered and enabling the user to flash the correct configuration.

consists of several components, such as the firmware executable itself,
chip-specific customizations, and configuration files.
The firmware file contains at least a flash utility, which is executed

has its own specific properties, such as the address where it should be
loaded during flashing, one or more destination flash pages, and
the flashing method that should be used.

To implement the devlink device flash functionality, the driver needs
to access both the device memory and the internal flash memory. The flash
memory is accessed using a device-specific program (called the flash
utility). This flash utility must be downloaded by the driver into
the device memory and then executed by the device CPU. Once running,
the flash utility provides a flash API to access the flash memory itself.
During this operation, the normal functionality provided by the standard
firmware is not available. Therefore, the driver must ensure that DPLL
callbacks and monitoring functions are not executed during the flash
operation.
Add all necessary functions for downloading the utility to device memory,
entering and exiting flash mode, and performing flash operations.
