For some reason, I can't get the driver to actually transition the hardware into peripheral mode. At first I was getting a lot of probe deferrals, based on not finding the regulators early enough in the boot, and I thought it was an issue with the gadget drivers loading before the driver could complete its setup. However, I switched everything to loading via modules, and now have less probe deferrals, but I still can't get the driver to activate. I see zero interrupts. In particular the routine hw_device_state (which turns on interrupts in the controller) is never called, because I can't get msm_otg_start_peripheral to actually kick the hardware. I've sprinkled the code in drivers/usb/chipidea and drivers/usb/phy/phy-msm-usb.c liberally with printks and WARNs to help me see what's going on, but I'm having a hard time tracing it down. I'm pretty sure I've got the DTS correct, but my USB config might not match yours. (Would you mind sharing your config?). I tried configuring the qcom,otg-control for user controlled mode setting (via debugfs), and even with doing "echo "peripheral" >/sys/kernel/debug/msm_otg/mode, it just wouldn't start the hardware (call hw_device_state(...1)). Any ideas you can provide would be welcome (e.g. for things to try, look at, etc.) My kernel is based on an internal Sony 3.13-rc6 kernel with clock and regulator patches applied, as well as your phy-msm-usb.c patches from November and your chipidea patches from yesterday.
