Previous implementation was not compatible with GlobalPlatform
API in the following ways:
- Registered mem IDs would begin from negatives when it should
have been greater than or equal to 0
- Register IOCTL would return 0 on success, when it should have
been returning a file descriptor.
- Register IOCTL would expect the user-space client to specify
TEE_SHM_* flags dictating its behaviour when in fact, libteec
never specifies flags.
This commit fixes all those issues. It uses nuttx/idr.h instead
of a linked list, and it uses `file_allocate` to provide file
descriptors for registered shared memory. Upon close(fd), the
memory is de-registered and freed accordingly. It also updates
the documentation accordingly.

This commit added a macro function clock_delay2abstick to calculate the
absolute tick after the delay.

This commit resolves a timing error caused by the round-up behavior in clock_time2ticks. In rare cases, this could lead to a two-tick increment within a single tick interval. To fix this, we introduced clock_time2ticks_floor, which guarantees the correct semantics for obtaining current system ticks.

Add timestamp for GNSS measurements and clock, for matching.
When recovering the combination of `GnssMeasurement` and `GnssClock` into
[GnssData](https://android.googlesource.com/platform/hardware/libhardware/+/
refs/heads/android14-release/include/hardware/gps.h#1748),
the reason for splitting is that the uORB buffer is not large enough to
accommodate `GnssData`, since different topics cannot guarantee the
same timing when publishing and subscribing data, we need an index to match.
WARNING: A new member "timestamp" of type uint64_t has been added at
the beginning of the struct "sensor_gnss_measurement" and "sensor_gnss_clock".

Adds support for SHM_REGISTER IOCTL. Registration can
be requested both against the driver (for automatic cleanup)
and against the secure OS (for sharing).
Introduces also `optee_{msg,free}_alloc()` to allocate
aligned memory for message arguments depending on the
`alignment` specified in the driver's private data. For
alignment greater than word size, memory is allocated on the
heap, otherwise it's allocated on the stack (similar to the
previous implementation but using `alloca()` instead).

This puts the mutex support fully inside nxsem, allowing
locking the mutex and setting the holder with single atomic
operation.
This enables fast mutex locking from userspace, avoiding taking
critical_sections, which may be heavy in SMP and cleanup

This commit refactors the logic of workqueue processing delayed and periodic work, and changes the timer to be set in `work_thread`. The improvements of this change are as follows:
- Fixed the memory reuse problem of the original periodic workqueue implementation.
- By removing the `wdog_s` structure in the `work_s` structure, the memory overhead of each `work_s` structure is reduced by about 30 bytes.
- Set the timer for each workqueue instead of each work, which improves system performance.
- Simplified the workqueue cancel logic.

In NuttX, the dq and the list are two different implementations of the double-linked list. Comparing to the dq, the list implementation has less branch conditions such as checking whether the head or tail is NULL. In theory and practice, the list is more friendly to the CPU pipeline. This commit changed the dq to the list in the wqueue implementation.

struct work_s
{

{
struct dq_entry_s dq; /* Implements a double linked list */

} s;

struct wdog_period_s ptimer; /* Period expiry timer */
} u;
worker_t worker; /* Work callback */
FAR void *arg; /* Callback argument */
FAR struct kwork_wqueue_s *wq; /* Work queue */
};
work_cancel() should determine whether the current work is
in the timer or has already entered the queue.
This judgment is indispensable because the structure is a union.
Whether it is interpreted as a timer or as a dq needs to be determined.
But this judgment seriously depends on the order of struct wdog_s and
struct dq_entry_s, once someone change the order of any, there is a bug.
So we decide remove the union, to improve the robustness.
For the work_s structure size will grow bigger, then we will provide a
another optimization patch

The MCP47X6 series consists of the following single channel DAC chips:
- MCP4706 (8 bit)
- MCP4716 (10 bit)
- MCP4726 (12 bit)
The driver supports the following configurations:
- gain
- power down
- voltage reference
Persistent configuration storage in the internal EEPROM is not
implemented.
The __flash qualifier only allows access to program memory below 64kB
mark (uses 16 bit pointer.) Since many chips currently supported
have more than that, this qualifier can prove insufficient.
When flagged __memx the compiler will use 24 bit pointer to access
the variable.
This adds filters field to icjx_config_s structure that is passed
as an argument in icjx_initialize function. This field allows to
configure I/O filters (control world 1 and 3) with three possible
filters or disable them at all.
The filter configuration is currently only configurable during the
initialization, not at run time (the same as current source)

There is no need for a gettid() syscall, as the thread ID is stable through
the life of the process. It is safe to put a copy of TID to TLS. This way
a user processes can access TID quickly via its own stack, instead of
having to use an expensive syscall.

On AVR architecture, the compiler apparently sometimes truncates NSEC_PER_TICK
to 16bit value, leading to clock_time2ticks returning incorrect results. This
was encountered while attempting to add tickless OS support for AVR
architecture but seemed to affect non-tickless mode of operation as well.
This patch marks NSEC_PER_USEC (and to be safe, USEC_PER_MSEC and MSEC_PER_SEC
too) as long.
This avoids unnecessary syscalls in memory protected builds, when mutex
lock/unlock can be done with only atomic counter access

Adds a device ID to ramtron_initialize, which is stored in the ramtron_dev_s structure.
This ID is used when calling SPI_SELECT to board specific logic to allow chip select on the SPI bus.
This change is NOT backwards compatible, as it changes the function signature of ramtron_initialize.
This implementation is based on the handling of chip select in nuttx/drivers/mtd/sst26.c:sst26_initialize_spi().
Additional Changes:
- Add MB85RS64V to ramtron supported parts list.

This PR is a follow-up of issue #15856 and the mailing list proposal "Proposal: Common IOCTL API for RF Modulation Technologies"
Before this PR, the IOCTL API for character-driven RF devices lacked a common
interface across different modulation technologies, such as LoRa, FSK, and
OOK. The result was, driver-specific IOCTL commands were created even when they
could be shared across multiple radios. This fragmentation made
application portability more difficult to maintain.
This PR will add a common API that can be shared across all new drivers.
Such as
* LoRa
* FSK
* OOK / ASK
* read() return struct

This ioctl clears the active fault inputs. Some faults can be latched
(still active even if the source is not active anymore), so they have
to be cleared from the software. The argument is a pointer to unsigned
long bitmask variable. This bitmask specifies which faults are to be
cleared.
The ioctl also can fetch the faults active prior to the clear. These
faults are saved to the argument specifying which faults are to be
cleared. Therefore passing zero bitmask means the driver will only return
active faults and clear none. Passing NULL pointer means the driver
will clear all active and return none.
The implementation of this ioctl is per driver.
