tested your scratch build on my wandboard quad i only had to load
usbmisc_imx as ci13xxx_imx was already loaded. I wonder if we need to
patch dracut to pull the module into the initramfs and it will just
work.
I think loading the modules should happen automatically and depends on
the dtb that is used. The ci13xxx_imx supports USB-OTG and there are
some references to that in the dtb for the Quad, but fewer for the
Duallite. At least, thats my understanding after a quick look.
Whatever should trigger loading if usbmisc-imx is unclear to me. Maybe
there should be an option to include the usbmisc_imx module in
ci13xxx_imx... Oh well, something to ponder about later. Ideas welcome!
Thanks,
Niels
