The addressing of the Packet buffer Memory Area (PMA) is done locally in the USB IP core in half-words with 16-bit. The `_ep_in_buf` and `_ep_out_buf` arrays which hold these USB IP local addresses in the PMA for initialized EPs therefore always use `uint16_t`.
If the MCU does not have an internal D+ pullup and there is no dedicated GPIO to simulate a USB disconnect, the D+ GPIO is temporarily configured as an output and pushed down to simulate a disconnect/connect cycle to allow the host to recognize the device. However, this requires an external pullup on D+ signal to work
If `RCC_CFGR_USBPRE` is defined, the USB device FS clock of 48 MHz is derived from the PLL clock. In this case the PLL clock must be configured and must be either 48 MHz or 72 MHz. If the PLL clock is 72 MHz it is pre-divided by 1.5, the PLL clock of 48 MHz is used directly.
When using DMA to transfer endpoint data from the RX FIFO to the
endpoint memory, the RXFLVL irq is not needed as that is already handled
by the DMA. Furthermore, servicing this irq anyway can cause the event
handling to interpret data from the FIFO as the endpoint and status
marker during the DMA transfer.
This commit masks the RXFLVL irq while DMA is used for the endpoint
transfers.
Since SLAAC now happens on the up event, the tests needs to ensure, that
`gnrc_ipv6_nib_iface_up()` is called before assuming SLAAC happened. For
the mock interface, this is done by gnrc_ipv6_nib_iface_up().
The definition in `pkg/esp32_sdk/Makefile.include` was evaluated by
`make` after the include paths were already set, resulting in
`ESP32_SDK_DIR` being empty in
INCLUDES += -I$(ESP32_SDK_DIR)/components
[...]
This in turn resulted in
cc1: error: /components: No such file or directory [-Werror=missing-include-dirs]

The parameters for parity and stop bits was confused, resulting in
the following compilation error with GCC 12.2.0:

This swaps the parameters.
The cpus for the sam*xpro series have some differences in make and Kconfig
Kconfig seems to be more verbose and make assumes samr34-xpro just uses saml21
The argument regif was removed from the shell command in https://github.com/RIOT-OS/RIOT/pull/18053,
so there is not much need to keep it in the ShellInteraction for that command.
The existence of the macros USB_OTG_GUSBCFG_ULPI_UTMI_SEL, USB_OTG_GUSBCFG_PHYIF and USB_OTG_GUSBCFG_DDRSEL depends on a specific STM32 line and not on STM32 itself. Therefore, the settings are made when the macros are defined.
