Introduce a new Wakeup Controller (WUC) driver API to manage wakeup
sources in low-power scenarios. The WUC API provides a standardized
interface for enabling, disabling, checking, recording and clearing
wakeup sources that can bring a device out of low-power states.

Ensure the modem is awake before sending socket data when low-power
mode is enabled. Add a PSM-aware wake path and a handshake to gate
offload I/O until the modem is ready.
Changes:
- hl78xx_sockets.c:
- Add HL78XX_PSM_WAKEUP_TIMEOUT_SECONDS (default 60 s).
- Add psm_cntrl_sem to socket data and initialize it at startup.
- Implement hl78xx_release_socket_comms() to release the semaphore
when the modem is ready for data after wake/registration.
- Implement hl78xx_send_wakeup_signal() to dispatch RESUME to the
modem state machine.
- Add hl78xx_ensure_modem_awake():
* If registered, return immediately.
* If in PSM/power-down, send wake, wait on psm_cntrl_sem up to the
timeout; on timeout set errno=EAGAIN and fail.
- Call hl78xx_ensure_modem_awake() from offload_sendto() and fail
early if the modem cannot be woken.
- Wrap a verbose post-process LOG_DBG() behind
CONFIG_MODEM_HL78XX_LOG_CONTEXT_VERBOSE_DEBUG.
Why:
- In low-power (PSM/eDRX) the modem may be asleep when the app tries to
send data. This change wakes the modem and blocks until it is ready,
preventing spurious send failures and lost payloads.
Impact:
- Behavior change for offload_sendto() under PSM:
* Returns -1 with errno=EAGAIN if wake times out.
- hl78xx_release_socket_comms() must be called by the core after wake
(done in driver on +CEREG/+KCELLMEAS paths).

Add a configurable GNSS processing mode for low-power operation and
teach the GNSS/LTE state machine to run GNSS without unnecessary CFUN
toggling when the RF path is already free in PSM. Improves energy
usage and reduces wake latency.
Kconfig:
- New choice HL78XX_GNSS_REQUEST_PROCESSING_MODE (depends on PSM):
* HL78XX_GNSS_PROCESS_POST_PSM (default).
* HL78XX_GNSS_PROCESS_PRE_PSM.
- Document PRE vs POST behavior and constraints.
Core (hl78xx.c):
- When GNSS is requested in low-power mode, defer to PSM-aware flow:
* PRE‑PSM: start GNSS on PSM entry.
* POST‑PSM: start GNSS after user wake.
- Avoid CFUN=4 when the RF path is already free due to PSM.
- Log intent and return early to skip legacy airplane path.
GNSS TU (hl78xx_gnss.c/.h):
- If PSM is active or just exited, skip CFUN=4 and start GNSS
immediately (RF path free).
- Start GNSS on timeout when RF is free (airplane or PSM), otherwise
queue until free.
- Cancel scheduled power‑down when GNSS actually starts.
- Handle LTE REGISTERED and DEVICE_AWAKE while GNSS is active:
* If LTE reclaims RF, modem auto‑stops GNSS; return to LTE flow.
* If GNSS exit occurs while CFUN=1 (PSM path), auto‑resume LTE
registration; in airplane mode, user restores CFUN=1.
- Clarify state doc: waiting for “RF free (airplane or PSM)” instead of
only airplane.
- Emit HL78XX_GNSS_EVENT_MODE_EXITED with status=false when auto‑stopped
by LTE.
Public API docs (hl78xx_apis.h):
- Document low‑power GNSS paths:
* ENTER: queued, start pre‑ or post‑PSM depending on Kconfig.
* EXIT: auto‑resume LTE in PSM path; airplane path still user‑driven.
Why:
- GNSS can operate while LTE hibernates in PSM; avoiding CFUN toggles
saves energy and time.
- PRE‑PSM maximizes GNSS acquisition window; POST‑PSM delivers fixes at
wake before LTE work.
- Clearer eventing for auto‑stop cases simplifies app logic.
Impact / migration:
- Behavior change for queued GNSS in PSM: CFUN=4 is no longer forced if
PSM already frees the RF path.
- Apps that assumed CFUN=4 during GNSS should rely on events instead.
- Consumers of MODE_EXITED should handle status=false (auto‑stop).
- New Kconfig choice requires MODEM_HL78XX_PSM=y to be effective.
Testing notes:
- Verified PRE‑PSM starts GNSS on PSM entry and cancels power‑down.
- Verified POST‑PSM defers GNSS until wake, then runs before LTE regs.
- Confirmed LTE REGISTERED during GNSS causes clean abort and return to
LTE path.
- Confirmed no CFUN changes when PSM already frees the RF path.

Introduce a low-power framework for HL78xx: new states, events, Kconfig
options, URC handlers, GPIO control, and an optional power-down timer.
Includes DTS pins for WAKE/GPIO6/VGPIO and a public wake API.
Board/DTS:
- swir_hl78xx_ev_kit.overlay:
- Add mdm-vgpio, mdm-gpio6, and mdm-wake GPIOs.
Kconfig:
- Add MODEM_HL78XX_POWER_DOWN when eDRX/PSM are both disabled.
- Add choice for power-down policy:
- MODEM_HL78XX_USE_DELAY_BASED_POWER_DOWN (+ delay seconds).
- MODEM_HL78XX_USE_ACTIVE_TIME_BASED_POWER_DOWN (+ active time).
- Tune eDRX defaults and add PTW value knob.
- Adjust PSM defaults (e.g., TAU default 15 minutes).
- Gate legacy sleep-delay settings when power-down is disabled.
Driver core (hl78xx.c/.h):
- New states:
- RUN_PMC_CONFIG_SCRIPT (apply PSM/eDRX/power-down).
- SLEEP (bus closed, UART suspended, wake via RESUME).
- New events (when low-power enabled):
- DEVICE_ASLEEP, DEVICE_AWAKE, LTE_PSMEV_UPDATE.
- +CEREG handler:
- Feed power timers, handle GNSS interplay, release socket comms
after register when low-power is active.
- +PSMEV handler:
- Track ENTER/EXIT, toggle WAKE pin, dispatch sleep/awake events.
- +KCELLMEAS handler:
- Update RSRP, mark registered on valid signal, release comms.
- Carrier-on / await-registered:
- Distinguish PSM entry vs coverage loss, route to SLEEP or retry.
- Avoid iface status run during initial PSM edge cases.
- Sleep state handlers:
- On enter: WAKE=0, release chat, close pipe, suspend UART, give sem.
- On bus closed: decide GNSS pre/post-PSM behavior.
- On resume: WAKE=1, resume UART, reopen pipe, proceed to GNSS or LTE.
- State-table safety:
- Use MODEM_HL78XX_STATE_COUNT for bounds checks.
- Log improvements and explicit state transition trace.
APIs (hl78xx_apis.c / include):
- Add hl78xx_wakeup_modem() to resume from SLEEP (PSM).
Chat/URC (hl78xx_chat.c/.h):
- Enable +KPSMEV URC and +KCELLMEAS URC when low-power is on.
- Provide disable-PMC script when low-power is off.
Config helpers (hl78xx_cfg.c/.h):
- Add PMC enabling and settings application:
- hl78xx_enable_pmc(), hl78xx_psm_settings(), hl78xx_edrx_settings().
- Power-down timer (when enabled):
- Init/cancel/query and feed functions via k_work_delayable.
- Feed timer on dynamic TX path to extend on activity.
- Add hl78xx_is_rsrp_valid() helper.
- Respect CONFIG_MODEM_LOG_LEVEL in cfg TU logging.
Misc:
- Expose hl78xx_release_socket_comms() for post-register gating.
- Guard init-fail path to require WAKE pin when low-power is on.
- Add RUN_PMC_CONFIG_SCRIPT transitions after RAT config.
Why:
- Reduce energy by using PSM/eDRX and a clean SLEEP state with bus and
UART suspended. Optionally power down the modem when DRX features are
disabled. Provide explicit wake and robust PSM detection.
Impact / migration:
- DTS must define WAKE/GPIO6/VGPIO if low-power is enabled.
- New state/event enums added; state table now uses *_STATE_COUNT.
- +KCELLMEAS URC is enabled unless GNSS blocks it (see comments).
- External users can call hl78xx_wakeup_modem() to resume from PSM.
- Power-down policy and delays are configurable via Kconfig.
Testing notes:
- Verified PSMENTER drives WAKE low and transitions to SLEEP.
- Verified RESUME re-opens UART, waits settle time, then proceeds.
- Confirmed GNSS pre/post-PSM flows per config.
- Checked power-down timer feeds on data activity and triggers OFF.

Add a GPIO driver for the Infineon CYW43439 WiFi chip that exposes
WL_GPIO0-2 as standard Zephyr GPIO pins. Pin 0 is the onboard LED
on Raspberry Pi Pico W and Pico 2 W boards.
The GPIO node is a child of the AIROC WiFi device node in the
devicetree. GPIO control is performed via the WHD gpioout iovar,
serialized with a mutex. A shadow register tracks pin state since
the CYW43439 does not support GPIO readback.

Clearing the status register in adxl367_thread_cb() introduces
a one-sample latency since any trigger handler invoking
adxl367_get_accel_data() has to wait until the next sample sets the
DATA_READY bit again. To fix this, identify trigger source by
reading status_copy register in adxl367_thread_cb(). This preserves

Use micro-units when converting readings to struct sensor_value.
The previous implementation used 100000-based scaling for fractional
values, while sensor_value expects 10^-6 units. As a result, converted
magnetic field values were reported as 10x the expected gauss value
instead of gauss, and the incorrect scaling caused apparent jumps in
the reported sensor readings.
Fix the conversions by using 1000000-based scaling and
sensor_value_from_micro().

Infineon PSOC4 parts share many ports with a single IRQ line. Using the
SHARED_INTERRUPT handler feature of Zephyr results in a very large IRQ
vector table. Instead structure in DT the idea that the ports are
sharing an interrupt with a sort of pseudo interrupt controller.
This also rectifies the need to ifdef on CAT1C/M0+. I added a note
making it clear that in those cases we likely need to rework the way
interrupts are done anyways as there's secondary interrupt
muxes/controllers involved.

The cancel-and-wait loop uses `while (retry_count--)` with a post-loop
check of `retry_count == 0`. This is broken in two ways:
1. When all retries are exhausted, the final post-decrement wraps the
uint32_t from 0 to UINT32_MAX, so the timeout check never fires and
the error is silently ignored.
2. When the controller goes idle on the last retry, retry_count is
legitimately 0 after the break, causing a false timeout report.
Replace with a simple for-loop and a bool flag to correctly distinguish
between the idle and timeout cases.

Depending on the on the actual variant some of the LSB are not

on the actual sensor resolution. In the worst this leads to
some pseudo-resolution in case the undefined bits are not
