    Subject[PATCH] usb: chipidea: Fix ULPI on imx51
    Date
    Workaround introduced for i.MX53 in be9cae2479f48 ("usb: chipidea:
    imx: Fix ULPI on imx53") seems to be applicable in case of i.MX51 as
    well. Running latest kernel on ZII RDU1 Board (imx51-zii-rdu1.dts)
    exhibits a kernel frozen on PORTSC access and applying the workaround
    resolves the issue.
