PS11, Line 9: #include <soc/soc_chip.h>
Since every SoC won't have soc_chip.h, compilation issue is seen. Need to remove this line.

PS11, Line 152: static void wifi_dsm_ddrrfim_func3_cb(void *ptr)
You can create a weak function here (example: get_wifi_sar_limits), which returns default value (0) and SoC can override that function if required.
