William Wu acf136a642 usb: dwc2: reinit for host mode during resume if lost power ... If the dwc2 controller lost power in suspend, we need to reinit the core when the dwc2 in host mode. There are two methods to set the dwc2 in host mode, and we need to reinit the dwc2 to host mode separately during resume. 1. Set the dr_mode to otg, and plug in OTG cable with the ID pin conneted to GND. In this case, we can reinit the core to device mode firstly, and later after do dwc2_hsotg_resume, it can trigger the ID status change interrupt if the OTG cable is still connected, then we can init for Host mode in the ID status change interrupt handler. 2. Set the dr_mode to host, and force the dwc2 to Host mode irrespective of ID input pin. In this case, we can't depend on the ID status change, so we do force host mode and init the core during resume. With this patch, it can fix the kernel panic if the dr_mode is set to host mode during resume. [ 134.975352] Unable to handle kernel write to read-only memory at virtual address 0000000000000068 ...
