fix the /tset/rt.os/files/open/T.open{2}:
O_RSYNC flag not set
According to the POSIX standard, when we set the oflags
for a file descriptor via open, retrieving these oflags
later via fcntl should yield the same values as those
passed during the open call.
Given this, if the value of O_RSYNC were zero, then even
if O_RSYNC were passed during the open call, it would not
be detectable in the oflags retrieved by fcntl.
Therefore, we need to define O_RSYNC as a non-zero value.
For this reason, we have chosen to set the value of
O_RSYNC to be the same as O_SYNC.

issue description:
task A: NSH:
1.open-> reboot->sync->task_fsfsync
2.nx_vopen-> context switch
3.fdlist_allocate: ----> 4.fsync->file_sync->assert(inode or priv is empty)
(new fd with empty filep)
5.file_vopen:
(init empty filep)
6.return fd
Task A allocates a new fd with an empty filep in fdlist_allocate. Before
it can fully initialize the filep in file_vopen, the NSH task triggers a
file - system sync operation. The sync operation encounters the empty
filep associated with the newly allocated fd, causing the assertion to
fail and the system to crash.
To resolve this race condition, we should modify the fd allocation
process. Instead of allocating a new fd with an empty filep first and
then initializing it later, we should use the file_allocate_from_inode
function. This function allows us to initialize the file structure first
and then bind it to the new filep when allocating the fd. By doing so,
we ensure that the filep is always properly initialized before it is
used in any file - system operations, thus preventing the assertion
failure and the subsequent system crash.

Introduce a single configuration option to provide strict transmit
priority ordering based on CAN ID.
The intention is to expose the user-visible behavior (strict TX
priority ordering) rather than the underlying implementation details.
Strict priority ordering is only meaningful when hardware transmit
buffer cancellation is available, so splitting this functionality into
separate configuration options was misleading and could result in
partially effective or incorrect configurations.

If multiple transfers are needed, the class driver can initiate
multiple urbs to meet the real-time requirements of the ISOC
endpoint. The class driver's urb record the buf address, length,

data location in the buf based on the callback number and length
returned.

This commit introduces a software-based fake capture driver that simulates
a 10Hz square wave with 50% duty cycle, enabling development and testing
of capture-related applications without requiring real hardware.
Background:
The capture driver subsystem requires hardware support (timers with input
capture functionality) to measure external signal frequency and duty cycle.
During development, testing, or on platforms without capture hardware, it's
difficult to develop and test applications that use the capture API.
Problem:
Without a fake/simulator driver:
- Developers cannot test capture applications without specific hardware
- Continuous Integration (CI) systems cannot run capture-related tests
- Applications cannot be developed on platforms lacking capture hardware
- Testing edge notification features requires complex hardware setup
- Difficult to reproduce specific timing scenarios for debugging
Solution:
This commit provides a software-simulated capture driver that generates
predictable capture events using a watchdog timer. The fake driver
produces a square wave signal at 10Hz frequency with 50% duty cycle,
allowing applications to test the full capture API without hardware.

This commit adds comprehensive signal notification support to the capture
driver, enabling applications to be asynchronously notified when capture
edge events occur on any channel, rather than having to poll for events.
Background:
The capture driver is used to measure frequency and duty cycle of external
signals by detecting edges (rising/falling). Previously, applications could
only retrieve captured values through periodic polling via CAPIOC_GETDUTY
and CAPIOC_GETFREQ ioctl commands, which is inefficient for event-driven
applications.
Problem:
Without event notification, applications must:
- Continuously poll the capture device to check for new events
- Waste CPU cycles in polling loops
- Experience higher latency in responding to capture events
- Cannot efficiently handle multiple capture channels simultaneously
Solution:
This commit adds a signal-based notification mechanism that allows
applications to register callbacks for specific capture channels and
edge types (rising, falling, or both). When the hardware detects the
configured edge, a signal is sent to the registered task.

This commit adds a new lower-half driver implementation for I2C bit-bang
that uses IO expander pins as the GPIO backend, enabling I2C bit-bang
functionality on systems where direct GPIO access is not available or
when I2C needs to be implemented using IO expander pins.
Background:
The existing I2C bit-bang driver (i2c_bitbang.c) provides a generic
upper-half implementation that requires a platform-specific lower-half
to control the SDA and SCL GPIO lines. Previously, each platform had to
implement its own lower-half using direct GPIO access.
Usage Example:
FAR struct ioexpander_dev_s *ioe = /* get IO expander */;
FAR struct i2c_master_s *i2c;
/* Initialize I2C bit-bang using IO expander pins 10 (SCL) and 11 (SDA) */
i2c = i2c_bitbang_ioexpander_initialize(ioe, 10, 11, 0);
if (i2c)
{
/* Use i2c master device normally */
}
