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.

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.

"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.

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.

This patch adds a document that describes why const variables need to be
copied into the RAM in AVR architecture for normal program flow in NuttX.
It then describes options of accessing them directly from the flash without
need to do any copying.
Patch was tested by building the documentation.
