Kconfig WIFI_AIROC should not depend on infineon SOC family selection

[ivanwagner]

Describe the bug
Murata manufactures the 1YN module which includes both WiFi and BT modules. The module hosts an Infineon CYW43439 processor and this module can comunicate via UART (BT) and SDIO (WiFi) with a host processor thus offloading the main processor in regards of networking.
It is not possible to select the following because of wrong Kconfig rules:

CONFIG_NETWORKING=y
CONFIG_WIFI=y
CONFIG_WIFI_AIROC=y
CONFIG_CYW43439=y
CONFIG_CYW43439_MURATA_1YN=y
CONFIG_WIFI_OFFLOAD=y
CONFIG_NET_OFFLOAD=y

• I am using a STM32U5 (stm32u5a9xx) processor as a SoC.
• I am testing on the main branch

To Reproduce

dts:

/dts-v1/;
#include <st/u5/stm32u5a9Xj.dtsi>
#include <st/u5/stm32u5a9njhxq-pinctrl.dtsi>
#include <zephyr/dt-bindings/input/input-event-codes.h>

/ {
	model = "Board module";
	compatible = "st,stm32u5a9j_dk";

};

&sdmmc1 {
	pinctrl-0 = <&sdmmc1_d0_pc8 &sdmmc1_d1_pc9
		&sdmmc1_d2_pc10 &sdmmc1_d3_pc11
		&sdmmc1_d4_pb8 &sdmmc1_ck_pc12
		&sdmmc1_cmd_pd2>;
	pinctrl-names = "default";
	status = "okay";

	/* Wifi configuration */
	airoc-wifi {
		status = "okay";
		compatible = "infineon,airoc-wifi", "infineon,airoc-wifi-sdio";

		/* Wi-Fi control gpios */
		wifi-reg-on-gpios    = <&gpioi 12 GPIO_ACTIVE_HIGH>;
		wifi-host-wake-gpios = <&gpioi 14 GPIO_ACTIVE_HIGH>;
	};

};

Steps to reproduce the behavior:

1. west build -b stm32u5a9j_dk -t menuconfig
2. See error

Expected behavior
It should include the necessary drivers in order to communicate with the 1YN module via SDIO (Wifi).

Impact
It's not possible to use a 1YN module connected to a host processor which is different than an Infieon chip.

We have filed an internal ticket to address this and should have a fix up in the next 24 hours. We had previously fixed this, but some MR regressed it. We are also going to develop an internal CI test to make sure future regressions don't occur or are detected ASAP.

Hi @ivanwagner ,

• I prepared PR drivers: wifi/airoc: Remove dependency on Infineon SOC family selection #77039 with fix.
• Also please refer to https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/infineon/cy8cproto_062_4343w/Kconfig.defconfig to check what addition Kconfig need for AIROC WIFI (NET_L2_ETHERNET, HEAP_MEM_POOL_ADD_SIZE_BOARD)

Also notice, that AIROC driver requires SDHC driver for SDIO communication, currently Zephyr doesn't support this driver for STM32 platforms (see https://github.com/zephyrproject-rtos/zephyr/tree/main/drivers/sdhc).

Regards,
Nazar
