Maybe a bit off-topic. It looks like second MicroClick modules are used as based board. Is there any plan to add them to zephyr as "capes"? IIRC for LAN8651 I also wanted to add it - in a way similar to:
https://github.com/zephyrproject-rtos/zephyr/tree/main/boards/shields/mikroe_wifi_bt_click
or
https://github.com/zephyrproject-rtos/zephyr/tree/main/boards/shields/mikroe_eth_click

but the reply was that we cannot tie to any specific board (like with microe_wifi_bt_click.

@lmajewski I was also thinking adding it as a shield in a second PR. At the moment I want to pass only a minimal implementation of the driver.

but the reply was that we cannot tie to any specific board (like with microe_wifi_bt_click.

I know that we should not tie drivers to specific shields but also Microship itself is using this module to demonstrate LAN9250 on their Quick Start Guide
