These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

usb_dc_ep_write may be executed in an ISR context and should therefore
not take a semaphore with a timeout. The semaphore was initially
introduced to prevent USB buffer overwrite when writing to an endpoint
in a loop. This is not requested anymore since there is an existing USB
transfer API available.

The various STM32 reference manuals sometimes define the USB endpoints
as IN or OUT only and sometimes as bidirectional, even in the same
manual. This is likely because the OTG implementation has one set of
registers for the IN endpoints and one other set for OUT endpoints.
However at the end a given endpoint address can both transmit and
receive data.
This causes some confusion how to declare the endpoints in the device
tree, and depending on the SoC, they are either the same number of IN
and OUT endpoints declared, or they are declared as bidirectional. At
the end it doesn't really matter given how the driver uses those values:
#define NUM_IN_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_IN_ENDPOINTS)
#define NUM_OUT_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
CONFIG_USB_NUM_OUT_ENDPOINTS)
#define NUM_BIDIR_EP NUM_OUT_EP
This patch therefore cleanup the driver, the DTS, and the DTS fixups to
only define the number of bidirectional endpoints.
In addition to the cleanup, that fixes a regression introduced by commit
52eacf16a2 ("driver: usb: add check for endpoint capabilities"), which
introduced a wrong check for SoC only defining the number of
bidirectional endpoints.

The STM32L4x2 SoCs need to control the isolation of the USB features
from VDDUSB. This is done through the PWR_CR2 bit USV, however the
current code checks for the PWR_CR2_PVME1 bit instead, which is only
available on Cat. 3 devices. This bug is also present int the HAL and
likely copied from there.
Replace the check by PWR_CR2_USV instead.

Transfer is an important concept of USB specification.
During a transfer, several packets can be transmitted.
Today the usb API only provides ep_read and ep_write
functions but the transfer concept is missing.
This is typically ok for basic drivers which don't have
to take care of how data is transfered/splitted.
However there are some drivers like CDC EEM, in which
transfer concept is important for packet management.
Moreover, current ep-write and ep_read method have a
different implementation in usb_dc_dw and usb_dc_stm32
device drivers. For example usb_dc_dw supports only
1-data-packet transfers due to its implementation.
This can increase latency and reduce performance.
I think this is something we need to fix/improve by
implementing better transfer management.
This patch introduces usb_dc_ ep_transfer method which
can be used to configure IN/OUT transfers. This allows
to configure and request different transfer sizes and
should prevent usage of the current stm32 temporary
buffer.
This method has asynchronous and synchronous mode.
Synchronous mode waits for transfer completion before
returning. Asynchronouse mode (irq safe) configures
the transfer and returns immediately, the provided
callback will be then called on transfer completion.
This also update ep_write and ep_read stm32 implementation
to use this new method but keep their behavior unchanged
for legacy reasons.
Note that for now this method is local to stm32 device
driver, however the goal would be to expose this function
as a new USB device driver API method so that class
drivers use it. This will request same implementation in
the usb_dc_dw_driver.
