Hello
We are using a bbappend on linux-ti-staging (master branch) based on this page (https://processors.wiki.ti.com/index.php/MUSB_Linux_Driver_Configuration). For some reason musb_am335x.ko, musb_dsps.ko and musb_hdrc.ko are still being built despite the fragment. Below is a copy of the fragment and also the bbappend file.
