Modify the dwc2 Kconfig and Makefile so that it will build the dwc2_gadget
driver when peripheral only mode is selected. The dwc_platform.ko and dwc2.ko
will get built when dynamic linked modules are selected for Host mode. For
peripheral mode only dwc2_gadget.ko will get built.
NOTE: You can build both host and peripheral as a dynamically linked module,
but be aware that if you insmod dwc2_gadget, then rmmod it, then insmod
dwc2 and dwc2_platform for host mode, this will not work. As the step to
rmmod dwc2_gadget.ko will turn off the clock to the USB IP. The dwc2 host
driver currently does not look to turn on a clock yet. A patch to fix that
will be coming soon.
Hi Dinh,
Sorry for the late response to this. The patch series looks OK to me,
except I didn't quite like the Kconfig and Makefile changes, so I have
redone those a little bit. Once the commit window for 3.15 opens, I will
send these patches on to Greg with my and Robert's acked-bys.
Thanks Paul! I was waiting for the 3.15 to open and resend. No longer
necessary now.
Dinh
