The strings "RPC2040" and "RP2040_IO_BANK0_GPIO0", presumably typos,
were used in place of respectively "RP2040" and "RP2040_IO_BANK0_GPIO".

This patch fixes an incorrect call to stm32_cap_initialize() in
stm32_bringup.c: the call was made without the channel parameter.
Instead of adding the channel in the call, the channel is selected by
stm32_cap_gpio() (first available channel).
This patch also fixes incorrect driver registration in
drivers/timers/capture.c: the driver was registered with the wrong
name (/dev/cap -> /dev/capture). Also added more error checking in
cap_register_multiple().

This commit introduces a timer capture driver for the STM32H7 series
ported from the STM32 F series.
The main changes include:
- A new generic timer capture driver for STM32H7.
- A lower-half driver to integrate with the NuttX capture subsystem.
- Kconfig options to enable and configure capture for various timers.
- Pin definitions for TIM1-4 capture inputs on the nucleo-h743zi.
- An update to `cap_register_multiple` to handle multiple device registration.
- An update to `stm32_bringup` to register the capture drivers.
The current implementation is based on a driver originally for PWM input,
and as such, it calculates duty cycle and frequency. It is also limited
to a single capture channel per timer.
The original implementation's `stm32_cap_init` in
`arch/arm/src/stm32h7/stm32_capture.c` has been modified to accept a
channel number instead of using a hardcoded 0 through
`STM32_CAP_CHANNEL_COUNTER`.
This serves as a foundation for future development of more comprehensive
input capture capabilities on STM32H7 platforms.
Tested by polling and reading `/dev/cap0-4` with
`ioctl(fds[i], CAPIOC_FREQUENCE, freq)` while sending a square wave signal to
appropriate pins and checking frequency.
Also tested by bypassing upper half driver and setting up capture on
TIM4 channels 1-4 as explained in #16762.

This fixes the same issue for other targets, which was already fixed for
xtensa in commit 50d94863.
After the signals have been delivered, the local irqs need to be
disabled until the context switch. But just calling
leave_critical_section(regs[xx]) will enable them if they were
enabled in the context.

Clear dma interrupt flags as before.
Change HTEF to HTF, fixes typo.
Remove ALL_FLAGS define. Clear CXFCR with all 1s like other instances do.
Handle half-transfer interrupt only if in circular mode.
Add ADC_HAVE_DMA guard around adc_rstart_dma. It is needed because priv->circular is guarded by ADC_HAVE_DMA.
After the signals have been delivered, the local irqs need to be
disabled until the context switch. But just calling
leave_critical_section(regs[REG_PS]) will enable them if they were
enabled in the context.
Any interrupt on this cpu before xtensa_context_restore() would set
the rtcb->xcp.regs to NULL, causing a crash in context restore.
Fix this by calling leave_critical_section(up_irq_save()) instead.

Many iMXRT MCUs have internally two USB OTG controllers, however
NuttX currently only supports one USB controllers. This patch will
prepare the "house" to support both ports at same time.

- Changed interrupt handling. Removed FARs. Added Kconfig options for selecting interrupts.
- Updated info and formatting.
- Formatting fixes.
- Formatting.
- Changed iten to regval.
- Removed Triggger
- Formatting fixes per Pull request.
- Changed private_types to have stm32_ prefix. Used depends on for DTS Kconfig Menu. Fixed formatting per PR.
- Fixed spacing of function prototypes.
- Fixed indent on line
- Added documentation for STM32H5 and Nucleo-H563ZI regarding DTS. Also added GPDMA support to STM32H5 documentation (previous PR). Made stm32_dts.c more modular. stm32_dts_activate is now much more readable. Added comments/descriptions to private functions. Lastly, added a nucleo-h563zi:dts configuration.
Set level high for unused interrupt trigger to avoid waking up from cold sleeping.

2. When using clang++ compiler to link, you also need to specify the corresponding arch, otherwise ld.lld will report an error due to arch mismatch.

return early due to signal interruption (EINTR). This makes the
main thread think the async operation is done, but the background
worker thread is still running—risking access to freed memory,
race conditions, crashes or undefined behavior.
Using nxsem_wait_uninterruptible():the main thread waits until the
worker thread finishes, preventing these issues.

AVR uses Hardward architecture with separate address space for program
memory (flash) and data memory (RAM). Normal program flow can only
access data memory which means that all variables - including const
variables - have to be copied into RAM to be accessible. (This happens
automatically during startup.)
It is possible to work around this limitation in software but that
can have severe impact on performance and/or API complexity. It is hardly
feasible to change NuttX interfaces in a way that would allow to make use
of this workaround.
On newer AVR families, there is an alternative option enabled by this patch.
These chips map part of their program memory (a 32kB window) into data
memory address space. This patch leverages this feature and adds support
for placing const variables into the mapped window. No copy to RAM is done
for them.
Const variables are therefore loaded directly from flash (not consuming
RAM) while still being available to be used by any NuttX interface.
Linker script of breadxavr board is changed to make use of these changes.
Tested by verifying string addresses - parameters in printf call
in a custom application (and also by running the application and verifying
its output.)
Documentation tested by build.
