Move the board-specific phy initialization from early boot into ifup phase. The
board specific phy initialization may need to implement delays, or bus
communication, for example via i2c bus.
These OS services are not necessarily available yet in arm64_netinitialize, and
PHY initialization is not necessary until the driver actually starts using it.
In addition, this allows the board to reset the ethernet phy at every ifup,
if needed for error recover.

The GPIO interrupt handler had hardcoded values that only worked
correctly for RP2350A (30 GPIOs). For RP2350B (48 GPIOs):
- Loop count was hardcoded to 6 registers but should be computed
based on RP23XX_GPIO_NUM (4 for RP2350A, 6 for RP2350B)
- Reserved bits mask was always applied at register index 3, but
for RP2350B register 3 contains valid GPIOs 24-31. This caused
interrupts for GPIOs 30-31 to be incorrectly discarded
- PWM port validation rejected valid ports 8-11 on RP2350B which
has 12 PWM slices instead of 8
Changes:
- Add RP23XX_GPIO_NREGS macro to compute number of interrupt registers
- Use conditional compilation to only mask reserved bits on RP2350A
where the last register has 6 valid GPIOs (bits 0-23)
- Fix PWM port validation to allow 12 ports on RP2350B

Gpio output value must be set on OLATA and OLATB registers.
Summary
Why is this change necessary?
This is a bug fix. The MCP23x17 driver was writing GPIO output values to incorrect registers, causing output
pins to not behave as expected.
What functional part of the code is being changed?
The MCP23x17 I/O expander driver (drivers/ioexpander/mcp23x17.c).
How does the change work?
The fix ensures GPIO output values are written to the OLATA and OLATB (Output Latch) registers instead of the
incorrect registers. The OLAT registers are the proper registers for controlling the actual output pin
states on the MCP23x17.
Impact
- User experience: No adaptation required. This fix corrects existing broken behavior.
- Build: No impact.
- Hardware: Affects boards using the MCP23x17 I/O expander.
- Documentation: None required.
- Security: No impact.
- Compatibility: Backward compatible - fixes incorrect behavior.
Testing
Build Host:
- OS: Ubuntu 22.04
- Compiler: arm-none-eabi-gcc
Target:
- Architecture: ARM (RP2350)
- Board: RP2350-based board
- Configuration: Custom config with MCP23x17 enabled over I2C0
Testing performed:
- Connected MCP23x17 to RP2350 via I2C0
- Attached an LED array to all 16 GPIO pins of the MCP23x17
- Configured all 16 GPIO as outputs
- Wrote a simple test application to toggle the LEDs on and off
- Before fix: LEDs did not respond correctly to output commands
- After fix: All 16 LEDs toggle on/off as expected

For the device-specific configuration space, the driver MUST use 8
bit wide accesses for 8 bit wide fields, 16 bit wide and aligned
accesses for 16 bit wide fields and 32 bit wide and aligned accesses
for 32 and 64 bit wide fields.
For a string in the virtio config space, we should should byte to
byte read operations to read this string, so add a api
virtio_read_config_bytes() for this.

This patch adds an AUTOSAR-style CRC library used by E2E functionality.
It introduces multiple CRC variants (CRC8, CRC16, CRC32, CRC64) and the
corresponding public headers and implementation files.
Key changes:
- Public headers: `include/nuttx/crc8.h`, `include/nuttx/crc16.h`,
`include/nuttx/crc32.h`, `include/nuttx/crc64.h` with new APIs for
specific polynomial variants and incremental (part) helpers.
- Implementations added under `libs/libc/misc/` for several polynomials:
- `lib_crc16h1021.c` (CRC-16 CCITT-FALSE)
- `lib_crc16h8005.c`
- `lib_crc32h04c11db7.c`
- `lib_crc32hf4acfb13.c`
- `lib_crc64emac.c`
- `lib_crc8h1d.c`
- `lib_crc8h2f.c`
- Build files updated to include the new sources.
This addition provides low-level CRC primitives required by higher-level
protocols and test suites.

Implement Linux-compatible TFD_TIMER_CANCEL_ON_SET flag for timerfd to
allow applications to detect discontinuous changes to CLOCK_REALTIME.
Background:
According to Linux timerfd_create(2) man page, when a timerfd is created
with CLOCK_REALTIME and TFD_TIMER_CANCEL_ON_SET flag is specified, the
read() operation should fail with ECANCELED if the real-time clock
undergoes a discontinuous change. This allows applications to detect
and respond to system time changes.
Implementation:
1. Add clock notifier infrastructure (clock_notifier.h/c) to notify
interested parties when system time changes
2. Implement TFD_TIMER_CANCEL_ON_SET flag support in timerfd
3. Register timerfd with clock notifier when flag is set
4. Cancel timer and return ECANCELED when clock change is detected
5. Notify clock changes in:
- clock_settime()
- clock_initialize()
- clock_timekeeping_set_wall_time()
- rpmsg_rtc time synchronization
Changes include:
- New files: include/nuttx/clock_notifier.h, sched/clock/clock_notifier.c
- Modified: fs/vfs/fs_timerfd.c to handle TFD_TIMER_CANCEL_ON_SET
- Modified: clock subsystem to call notifier chain on time changes
- Modified: rpmsg_rtc to notify time changes during sync
Use case example:
Applications using timerfd with absolute time can now detect when
system time is adjusted (e.g., NTP sync, manual time change) and
take appropriate action such as recalculating timeouts or updating
scheduled events.
