Erwin Rol 65434f58dd drivers: spi_ll_stm32: refactor DMA support
- Fix GPIO CS timing when using DMA. When using GPIO CS the
  CS select was enabled after the DMA started the transfer,
  resulting in the first few bits being transfered while
  CS was still disabled.

- Fix TX or RX only DMA transfers. When only a RX or only
  a TX transfer was requested the DMA never finished.

  For the RX only cause the size on the transfer was
  calculated by taking the TX buffer length (0), this
  caused problems.

  For the TX only transfer the RX buffer was set to NULL,
  this caused the DMA to acctually writing data to the
  adress 0x00000000. By using the dummy destination buffer
  it now only writes to valid memory.

- Add semaphore to signal that DMA is ready, instead of
  just busy waiting.

Daniel Leung d1f57be7be i2s: cavs: cast device struct to void ptr for DMA user data
In the I2S CAVS driver, the DMA user data simply points to
the device struct. However, after the change to const-ify device
struct, this causes warnings from compiler because the user_data
assignment would discard the const qualifier. The user_data is
being used to point back to the device struct, and the DMA
callbacks are already casting the user data argument into
a const device struct. So it's a simple fix by casting
the device pointer to void pointer at device creation.

Fixes #28016

Andrzej Głąbek 460a97d378 drivers: usb_dc_nrfx: Enable and properly initialize nrfx POWER driver
This is a follow-up to commit 701e9befe4.

The NRFX_POWER Kconfig option should be enabled together with USB_NRFX,
not with CLOCK_CONTROL_NRF, as the USB driver is the actual user of
the nrfx POWER driver.

This patch adds also missing initialization of the nrfx POWER driver
and refactors a bit the usb_init() function introduced in the commit
mentioned above, so that it does not redefine the DT_DRV_COMPAT macro
and uses for conditional compilation the same Kconfig option that is
the dependency of NRFX_USBREG.

Jordan Yates 1d0acd2bb8 drivers: serial: uart_rtt async support
Add support for `CONFIG_UART_ASYNC_API` to the uart_rtt driver.
As RTT provides no mechanism for knowing when new data has arrived,
the reception commands all return errors.

This fixes hard faults when asynchronous calls are made on the uart_rtt
driver, in addition to providing a small level of functionality.

Jordan Yates 3e33d73381 drivers: serial: uart_rtt converted to devicetree
Instantiate RTT UART instances from devicetree nodes instead of from
Kconfig symbols. While RTT is implemented using software, not hardware,
it is emulating a hardware device, and thus should be configured through
devicetree. This allows the simulated UART device to be selected via
devicetree aliases and chosen nodes.

The following devicetree snippet will instantiate RTT channels 0 and 2
as UART devices.
```
/ {
	rtt0: rtt_terminal {
		compatible = "segger,rtt-uart";
		label = "rtt_terminal";
		status = "okay";
	};

	rtt2: rtt_secondary {
		compatible = "segger,rtt-uart";
		label = "rtt_app_specific";
		status = "okay";

Modify the ethernet driver to use TX complete interrupts.
Adds HAL ethernet TX complete callback and locking semaphore.

Due to changing behavior/content of the TX DMA descriptors
on STM32H7 series, based on the state of the IP,
it is more reliable to wait for the TX complete interrupt to check
for DMA end of transmission event. This avoids polling the
DMA_DESC_OWN bit in the descriptors.

Peter Bigot 669a0d6f5b drivers: eeprom: reduce priority of at2x initialization
The default priority for I2C controller initialization is POST_KERNEL
60 (SPI 70), while the default priority for device configuration is
POST_KERNEL 50.  Thus the EEPROM is being initialized before its
controller.  While for this driver that wouldn't be an issue recent
changes mean the device lookup returns NULL before the device is
initialized.

Change the AT2X priority to 75 so it falls between the I2C and SPI
drivers and the default ethernet priority (80), since some ethernet
controllers may store the MAC address in EEPROM.

Tomasz Bursztyka 4dcfb5531c isr: Normalize usage of device instance through ISR
The goal of this patch is to replace the 'void *' parameter by 'struct
