Initial I2C implementation such that I2C sending and receiving now
works well enough to use the BMP280 driver for a BMP280 device connected
to any of I2C0-I2C6 on the default pins. I2CTOOL also works for these
interfaces.
Functionality for "no stop" and "no start" options is not present.
Implementing that is not clear from the peripheral datasheet and will be
a challenge.

This commit adds documentation to the almost empty `calib_udelay` page
as part of #11081. It provides reasoning for the example, an explanation
of what it does and why `CONFIG_BOARD_LOOPSPERMSEC` is necessary, and
also shows some example console output of the program.

In certain cases, when the event-wait thread is awakened,
it needs to know the specific mask bit that triggered it,
so that it can branch to different paths accordingly.
This patch introduces the nxevent_getmask function to address this requirement.

There are cases that users do not want the event wait object to be allocated automatically
in the stack as a temporary varialbe in nxevent_tickwait, since multiple threads will
access the varialbe, they want to allocate the object as a global variable for safety
control or easy debug. To solve this problem, this patch add a new function nxevent_tickwait_wait
implementation to give user the chance to pass the global wait object to it.

"tc397" is a chip name which is not appropriate to act as a board name.
the board supported here is actually "a2g-tc397-5v-tft".
The correct definition is : tricore is arch name, tc3xx is arch family
name, tc397 is chip name and the borad name is a2g-tc397-5v-tft
Introduce EXT1 wakeup functionality to the ESP32-S3 power management
subsystem. With this feature, the ESP32-S3 can wake up from PM_STANDBY
or PM_SLEEP when one or more RTC GPIOs trigger the EXT1 condition.
Changes include:
- Added EXT1 wakeup configuration and preparation logic in rtc code.
- Integrated EXT1 handling in pmstandby() and pmsleep().
- New board-level Kconfig options under ESP32-S3 DevKit menu:
- CONFIG_PM_EXT1_WAKEUP: enable EXT1 wakeup support
- CONFIG_PM_EXT1_WAKEUP_RTC_GPIO<n>: select RTC GPIOs as wake sources
- CONFIG_PM_EXT1_WAKEUP_TRIGGER_MODE: choose wakeup on HIGH or LOW level
- Fixing Kconfig style
- Fixing comments standard
- Adding PM documentation for esp32s3-devkit
Impact:
- No build impact unless CONFIG_PM_EXT1_WAKEUP is enabled.
- When enabled, ESP32-S3 can wake from low-power states via RTC GPIOs.
- No new public API introduced; controlled via board Kconfig.
Tested on ESP32-S3 DevKit:
- Configured GPIO4 and GPIO5 as EXT1 wake sources.
- Verified wakeup from light sleep and deep sleep on external signals.
- Wakeup reason correctly reported as EXT1.

Add support for pthread_{get|set}concurrency support.
NuttX uses 1:1 threading model (every pthread is a kernel-managed thread),

Add support for sigsetjmp() and siglongjmp().
This implementation is build on top of setjmp() and longjmp().
sigsetjmp() in that case must be implemented as a macro otherwise
we lose setjmp context.
siglongjmp() is kept as inline function to satisfy the PSE52 VSX
tests requirement.
An alternative implementation requires writing these function in
assembly code for each architecture.

The GNSS lower-half driver for facilitating the implementation of uORB
GPS/GNSS device drivers was lacking documentation. Contributors cannot
be expected to implement their drivers correctly with this framework if
it is undocumented. This change adds documentation for how to use the

users to use this framework if implementing their own GNSS driver.

This commit expands RPC support for the OP-TEE driver using 2 files:
1) drivers/misc/optee_rpc.c
* Add support for RPCs that can be handled directly by the kernel.
* Can delegate RPC handling to optee_supplicant.c for RPCs that
need userspace interaction.
2) drivers/misc/optee_supplicant.c
* Enable communication between the userspace TEE supplicant and the
kernel driver.
Additional changes were needed to the following files:
1) drivers/misc/optee.c
* Add ioctls used SOLELY by the userspace TEE supplicant.
* Register /dev/teepriv0 if the supplicant is enabled in Kconfig
* Add OPTEE_ROLE_CA and OPTEE_ROLE_SUPPLICANT conditionals to
differentiate paths, between a normal Client Application (CA)
and the TEE supplicant.
* Change some functions from static to "public" to reuse them
in other C files.
* Adjust optee_to/from_msg_param() to work with RPCs.
2) drivers/misc/optee_smc.c
* Call the RPC handler from optee_rpc.c
3) drivers/misc/optee_msg.h
* Add definition needed for RPCs
4) drivers/misc/tee.h
* Add ioctl definitions
* Add TEE_SHM_SUPP flag, checked when unregistering supplicant
memory.
5) Documentation/guides/optee.rs
* Add documentation for RPCs and the supplicant.
6) drivers/misc/{CMakeLists.txt, Make.defs}
* Account for the new files.
7) drivers/misc/Kconfig
* Add DEV_OPTEE_SUPPLICANT option to enable/disable the supplicant
driver.
