Hi. I managed to run UWE5621DS (wifi and bluetooth) on OpenWRT (linux kernel 6.6). WiFi works stably in client mode. Bluetooth too. It looks like we are tinkering with the same board on RK3566 - as far as I can judge by the DTS dump you provided. This is what I got in the end: https://github.com/adron-s/openwrt-rk3566-leopad-10s
