After irq_dispatch finished, the interrupt stack will be checked to
determine whether overflow occurs.
The relevant configuration reuses the configuration of stack overflow
detection during context switching.

Many different architectures re-implemented the exact same code for
`up_*delay` because it was originally written as architecture dependent
code. Busy-waiting can be done regardless of architecture, so this
commit moves that duplicated implementation to a common file with weak
definitions so that individual architectures (see tc32) are still able
to override the definition if needed/desired.
Default implementation is not included if ARCH_TIMER is enabled, since
it is more accurate and provides its own weak definitions to override.

Added ioctls and functions for watchdogs 2 & 3. Modifed wdog1 functions. Needs testing.
Fixed issues with started variable.
Change to add only 3 ioctls, a config for each watchdog. Created cfg structures for watchdog1 and watchdog23. Added code to set difsel register. stop conversions before changing watchdog configs. Other logic changes.
Define AN_STM32H5_FIRST and AN_STM32H5_NCMDS in nuttx/analog/ioctl.h
Remove hardcoded AN_STM32H5_FIRST.
Style fixes.
Fix thershold for watchdog1
Got working watchdog driver with queue and signal. Needs polish.
Refined isr for watchdogs. Added value back to event. value is more accurate, but not guaranteed. It accomdates dma.
Used stm32_adc_sigcfg_s structure inside stm32_adc_sig_s structure. Used common naming for ioctls.
Added stopifstarted and startifstopped for setting watchdogs and other bits. Added adc_reset_dma, which must be run after stopping conversions in circular mode, because buffer and conversions become misaligned. Other refinements.
Added guard around adc_reset_dma, added comment blocks to new functions
NuttX style fixes.
Add return value to wdog configure functions.
Correct number of stm32h5 adc ioctls.
Minor style fix.
Reduce watchdog commit to fit NuttX standards. Remove Queue and Signal aspects. Added Kconfig to initialize watchdog.

Added guard around code referencing priv->circular. Added adc_watchdog config for testing watchdog1 with adc1. Added documentation about adc_watchdog config.
Adjusted documentation for adc_watchdog config. Added detailed test procedure.
Longer underline under adc_watchdog title.
Add code for differential adc calibration. Need to calibrate both single-ended and differential if a given adc has both single-ended and differential channels.
Fixed typo.
Initialize watchdog1 parameters at compile time when configured. Added comments to new elements in stm32_dev_s. Confirmed style is good.
Add proper guards around ADC WDG1 variables and functions.
Implemented feedback per raiden00. 1. Changed to use old chanlist type uint8_t. 2. Added smpr1, smpr2, and difsel variables to stm32_dev_s structure. 2. smpr1 and smpr2 are initialized to board defined values if BOARD_ADCx_SMPRx is defined, otherwise initialized to default. 3. difsel initialized to BOARD_ADCx_DIFSEL if defined, otherwise use default (0) for all single-ended.

so only the scheduling information needs to be updated in doirq.
In the arm-a/r architecture, interrupts and syscalls are independent,

This patch addresses several issues and adds enhancements to the WWDG
(Window Watchdog) implementation for the STM32H7 platform. The changes
include:
- Extend the definitions of WWDG_CFR_PCLK1 macros to support dividers
up to 128, and update the stm32_settimeout() function to consider this
extended range.
- Fix the "elapsed" calculations in the stm32_getstatus() function to
ensure correct time remaining calculations.
- Clear the EWIF (Early Wakeup Interrupt Flag) bit in the stm32_start()
function, as this bit might be set by hardware before the watchdog is
actually started.
- Initialize the WWDG clock in the RCC_APB3ENR register and set the
RCC_GCR_WW1RSC bit as per the STM32 reference manual to ensure proper
behavior when enabling the WWDG1.

Since the alignment of the signal context is affected by XCPTCONTEXT_SIZE in
different Kconfig, sometimes the stack pointer is not aligned to 8 bytes, this
is not what the software and compiler expect, for example, if va_list() obtains
wide data of type long long, the offset will be wrong, So in this commit, we set
stack-aligned the base offset so that the correct offset will be set during context
restoration.
1. test code:
| void signal_handler(int signo, siginfo_t *info, void *context) {
| long long ttt = 1024000;
| printf("%lld\n", ttt);
| }
|
| struct itimerspec its = { .it_value.tv_sec = 1,
| .it_value.tv_nsec = 0,
| .it_interval.tv_sec = 1,
| .it_interval.tv_nsec = 0
| };
|
| int main(int argc, FAR char *argv[])
| {
| struct sigevent evp;
| timer_t timer_id;
|
| memset(&evp, 0, sizeof(evp));
| evp.sigev_notify = SIGEV_SIGNAL | SIGEV_THREAD_ID;
| evp.sigev_signo = SIGALRM;
| evp.sigev_notify_thread_id = gettid();
|
| timer_create(CLOCK_REALTIME, &evp, &timer_id);
|
|
| struct sigaction sa;
| memset(&sa, 0, sizeof(sa));
| sa.sa_sigaction = signal_handler;
| sa.sa_flags = SA_SIGINFO;
| sigemptyset(&sa.sa_mask);

The functions `hw_write_masked` and `hw_xor_bits` (as defined in
pico-sdk) were defined in NuttX twice.
Additionally these definitions were in conflict (one lacked the
`volatile` modifier).
Now these functions and their dependencies are defined in a new header
file.
Its name is based on the filename of the original definition in
pico-sdk:
src/rp2_common/hardware_base/include/hardware/address_mapped.h
This change should fix the potential issue of GPIO operations failing
due to compiler optimizations caused by the absence of `volatile`.
