    Subject[PATCH 10/24] ARM: OMAP3: cm-t3517: Adapt to ehci-omap changes
    Date
    Add 2 platform devices for 'nop-usb-xceiv'. These will be used
    as PHYs for HS USB ports 1 and 2 so provide binding information
    for them.

    Model RESET for HS USB Ports 1 and 2 as GPIO fixed regulators and
    link them to the 2 PHYs we just created.
