Ok, it seems  the driver does not work built-in, due to firmware issue:

root@...uan:/home/user# dmesg | grep wl12
[    1.018951] reg-fixed-voltage regulator-wl12xx: GPIO lookup for
consumer (null)

/lib/firmware/ti-connectivity/wl128x-nvs.bin
root@...uan:/home/user#

Ideas welcome... ... ... am I supposed to compile wl128-nvs.bin into
the kernel using EXTRA_FIRMWARE?
