Make writes to `the_same` "observable behavior" by declaring it
`volatile` to prevent compiler optimization rather than GCC specific
attributes.
Likely, either doesn't a super good job at resulting in constant
time code. But with the plain text password stored in flash, this
likely also isn't what should keep one up at night when actually using
this module.
`clang` doesn't propagate the packed attribute to members. I think
this incorrect, but explicitly adding it won't hurt and makes clang
happy. So let's have it.
Some of the `static inline` functions are only used in some
configurations, depending on the preprocessor. Explicitly disable the
warning to allow compilation with clang.
Drop type qualifiers in front of anonymous bit fields (padding for
reserved bits) for compatibility with `clang++`. A four line bash
script was added to ease fixing new vendor header files.
Designated initializers make the code much more readable and are part
of the C standard since C99. C++ with C++20 finally caught up.
Until we switch to that C++ version, let's disable the annoying
warning rather than reducing the code quality for the sake of
strict C++ compatibility of our headers.
With GCC, the C++ compiler knows all builtin C include paths *and*
all builtin C++ include paths, but the C compiler only knows the
C include paths. Hence, let's use the C++ compiler to collect
the include paths.

19816: drivers/lcd: code deduplication for st7735 and ili9341 r=aabadie a=gschorcht
### Contribution description
In preparation for the parallel interface support the following changes were made:
1. The code for basic communication (acquire/release SPI device, SPI transfers), which were always duplicated by copy & paste in each display driver again and again, has been moved to the LCD driver as low-level functions that are now used by the display drivers. These low level function allow
- code deduplication and
- to define a more abstract communication interface that can then be extended later by parallel communication interface
2. Identical GPIO initializations has also been moved from display drivers to the LCD driver.
3. Using a default implementation of `lcd_set_area` function allows further code deduplication.
Finally, the `ili9341` and `st7735` drivers only implement the inialization sequence for the LCD driver IC.
### Testing procedure
`tests/drivers/ili9341` should still work for a board with an ILI9341. Tested with `esp32-wrover-kit`.
`tests/drivers/st7735` should still work for a board with a ST77xx. Tested with `esp32s3-usb-otg`.

19777: cpu/avr8_common: Prepare for rework ISR r=benpicco a=nandojve
### Contribution description
This prepares for rework how ISR is handled for AVR-8 platform. It is not expected changes on the behavior but tests on other boards were welcome to avoid regressions.
#### Improvements
* Split UART state from ISR states. Now it is necessary two variables and GPIORx registers are automatically selected when available.
* UART states now supports up to 8 UARTs.
* Added AVR8_ISR macro do clean-up and hide internals related to ISR processing. This allows changes on ISR without any other changes on drivers.
### Testing procedure
Tests were conducted using atmega328p-xplained-mini and atxmega-a1u-xpro and the zigduino board was only built. The example thread_duel was used to test regressions.

19764: drivers/shield_w5100: add module for the W5100 Ethernet Shield r=benpicco a=maribu
### Contribution description
This module provides no more than the correct configuration parameters for the `w5100` driver using the Arduino I/O mapping features. But by doing so, it will work out of the box with every mechanically and electrically compatible board for which the Arduino I/O mapping features are implemented.
19781: cpu/nrf{53,9160}: add pwm support r=benpicco a=dylad
### Contribution description
This PR moves the nRF52 PWM driver to `cpu/nrf5x_common` to allow nRF9160 and nRF53 to use this driver.
IP is identical on these families.
I didn't test on nRF9160DK and I didn't test if there is any regression on nRF52-based board as I don't have any so tests are welcome !
However it works fine on nRF53-based board.
### Testing procedure
Flash the `tests/periph/pwm` test application on `nrf5340dk` or `nrf9160dk`.
You can then use the `osci` command to make the onboard LEDs "breath".
You can also attach an oscilloscope and/or logic analyzer to watch the signal.

19813: buildsystem: fix kconfig mismatches r=gschorcht a=maribu
### Contribution description
This adds three commits each addressing a deviation between dependency resolutions done with and without Kconfig. Hopefully, these in combination should fix the nightly builds.
### Testing procedure
For each `$failing_board` and `$failing_app` pair in the latest nightly build, do:
```
make BOARD=$failing_board -C $failing_app TEST_KCONFIG=0 info-modules > ~/without-kconfig
make BOARD=$failing_board -C $failing_app TEST_KCONFIG=1 info-modules > ~/with-kconfig
diff -rupN ~/without-kconfig ~/with-kconfig
```
should yield an empty diff other than the `=== [ATTENTION] Testing Kconfig dependency modelling ===`.

In KConfig `MODULE_ST7789` now is hidden module that automatically

Without KConfig presence of the TFT is assumed in anycase, with KConfig
it is optional. This turns the opt-in into an opt-out to match behavior
with make by default, fixing the nightly breakage.

19808: boards: add ESP32-S3-USB-OTG support r=benpicco a=gschorcht
### Contribution description
This PR provides the support for the [ESP32-S3-USB-OTG](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s3/esp32-s3-usb-otg/user_guide.html) board.
The SD card can only be used in SPI mode at the moment. As soon as PR #19786 is merged, the SD/MMC support can be enabled and the SD card can then be used in SD mode with 4-bit data bus width.
The display uses uses the ST7789 driver IC that is compatible with the ST7735. For that purpose the ST7735 driver is extended by a pseudomodule definition `st7789` for the ST7789 which is enabled by the board and enables automatically the `st7789` (e57c48a33ee2a869c15603788e5306ba066f91cf). Vise versa, board's `Makefile.dep` enables automatically the `st7789` pseudomodule if the `st7735` is used. The pseudomodule `st7789` is just used to increase the upper limit for supported lines. This change is also part of PR #19807.
~The PR includes a very small documentation fix for ESP32-S3-DevKit board that was noticed during the development of this board definition (1155b6ac1b8efa39d8a0bd7150e602095159fdc1).~

- [x] tests/periph/pwm

### Contribution description
This PR enables support for `periph_rtt` on both nRF9160 and nRF53.
This PR is based on #19803
I was only able to test on nrf5340dk-app as I don't have access to any nrf9160-based board.
Here is `test/periph/rtt` output for reference on `nrf5340dk-app`:
### Testing procedure
flash `tests/periph/rtt` on `nrf9160dk` or `nrf5340dk-app` and check the results.

### Contribution description
This PR fixes the display configuration for the ESP32-S2 LilyGO TTGO T8 (also known as LilyGo T-Display S2) which uses a ST7789 as display driver IC that is compatible with the ST7735.
For that purpose the ST7735 driver is extended by a pseudomodule definition `st7789` for the ST7789 which is enabled by the board and enables automatically the `st7789` (f57b6b70b8). Vise versa, board's `Makefile.dep` enables automatically the `st7789` pseudomodule if the `st7735` is used. The pseudomodule `st7789` is just used to increase the upper limit for supported lines.
### Testing procedure
