usb: host: ohci-at91: suspend/resume ports after/before OHCI accesses
commit 00de6a5 upstream. On SAMA7G5 suspending ports will cut the access to OHCI registers and any subsequent access to them will lead to CPU being blocked trying to access that memory. Same thing happens on resume: if OHCI memory is accessed before resuming ports the CPU will block on that access. The OCHI memory is accessed on suspend/resume though ohci_suspend()/ohci_resume().
