50fa6bdd5e wifi: eswifi: Parse async messages
The eswifi controller can generate events via asynchronous messages
which can be polled via the 'MR\r' command. The messages will have a
Start Of Message Asynchronous [SOMA] and End Of Message Asynchronous
[EOMA] delimiters.

a614a026b7 dts: Rename DT_.*_GPIO_* to DT_.*_GPIOS_*
Convert DT_.*_GPIO_{CONTROLLER,PIN,FLAGS} ->
	DT_.*_GPIOS_{CONTROLLER,PIN,FLAGS)

Used the following commands to make these conversions:

git grep -l DT_.*_GPIO_CONTROLLER | xargs sed -i 's/DT_\(.*\)_GPIO_CONTROLLER/DT_\1_GPIOS_CONTROLLER/g'
git grep -l DT_.*_GPIO_PIN | xargs sed -i 's/DT_\(.*\)_GPIO_PIN/DT_\1_GPIOS_PIN/g'
git grep -l DT_.*_GPIO_FLAGS | xargs sed -i 's/DT_\(.*\)_GPIO_FLAGS/DT_\1_GPIOS_FLAGS/g'

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.

654d93999e wifi: eswifi: Add controller at command helpers
Create eswifi_at_cmd and eswifi_at_cmd_rsp helpers, allowing to send an
at command and parse the at response. These methods return success if
the response contains the OK* string. The eswifi_at_cmd_rsp method
extracts response content/size (DATA) on success.

*Response format is:
\r\n[DATA]\r\nOK\r\n>
Where DATA can be arbitrary (ASCII or not).

77149642f6 driver: wifi: eswifi: Fix how we get SPI bus

DT_INVENTEK_ESWIFI_ESWIFI0_BUS_NAME as its generated from the device

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
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

0b8fde39e4 driver: wifi: Add inventek es-WiFi driver
es-WiFi compatible modules use IWIN AT command set.
This driver is split into several layers:
- bus layer: interface to transmit AT commands (SPI, USB, UART...)
- core layer: es-WiFi module management (state, scan...)
- offload layer: TCP/IP offload operations (connect, listen...)

This driver has been tested with stm32l4 disco iot board
(disco_l475_iot1) and the wifi sample:

$ select wifi
$ scan
$ connect "CISCO" 5 password
$ select net
$ tcp connect 192.168.1.21 4242
$ tcp send HelloWorld!
