2012-08-16usb: gadget: tegra_udc: Enable DR IRQ in udc_startPreetham Chandru
Currently dr_controller_run() is called only during otg state change. When we unload a gadget driver, for example g_mass_storage gadget driver, dr_controller_stop() is called but when it is loaded back dr_controller_run() won't get called becasue of the if condition failure. i.e if (!udc->transceiver) { dr_controller_run(udc); } So when the gadget driver is loaded for the second time without removing the cable (i.e without otg state change), the device won't get enumerated on the host because DR IRQs are not enabled. This CL fixes the above issue.

Becasue of a previous workaround, suspend/resume pair is implemented as suspend/complete pair in the driver's dev_pm_ops field. If any driver suspend routine (which is called before otg suspend) failed, then tegra_otg_resume() will be called even tegra_otg_suspend() is not called. This will cause disable the OTG clock, and OTG will not generate any more IRQ. Ideal fix would be use suspend/resume pair to implement the dev_pm_ops, but this might break previous workaround. This patch check suspend() routine is called or not in the resume routine; even we use suspend/ resume pair in the future, it will not cause bad behaviour.
