wl12xx: latest firmware/utils

Wireless wiki (http://wireless.kernel.org/en/users/Drivers/wl12xx/calibrator)
recommends to use following repo to get the latest ti-utils:
https://github.com/gxk/ti-utils
This repo was once forked and got some updates:
https://github.com/idor/ti-utils, then there occurred another fork
(https://github.com/TI-OpenLink/ti-utils) with even more changes.

Yesterday I've sent a patch to the TI-OpenLink/ti-utils
(https://github.com/TI-OpenLink/ti-utils/pull/4) and got an answer,
that this repo won't be supported anymore. So where is the upstream
version then?

TI-OpenLink/ti-utils also provides wl127x firmware version
6.3.10.0.137, but the latest official fw
(https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ti-connectivity)
has version 6.3.10.0.133. Is the firmware version 6.3.10.0.137 ready
for upstreaming?
