Hi All,
I'm new to this USB driver development so posting this email. Currently,
I'm using Kernel version 3.12-rc5
In my SoC, there's Synopsys' DWC3 USB controller configured in device
mode. This is integrated with our internal USB3.0 PHY and USB 2.0 PHY
taken from synopsys. I'm done with the initial coding and now I want to
test the glue layer logic implemented. I have compiled and statically
linked the drivers.
When I boot my kernel, I see that the PHY and the DWC3 driver is probed
successfully. However, the device doesn't enumerate. I debugged this and
found that the device specific registers are not configured at all. More
debugging followed and I figured out that the probe for zero gadget is
called before the phy and the device is probed.
So, how can I test the driver by *not* modularizing the phy and the
controller drivers.
I would be thankful for any help.
Regards
Amit Virdi
