    Subject[PATCH v5 15/23] usb: phy: Probe phy devices on demand
    Date
    When looking up a phy through its OF node, probe it if it hasn't
    already.

    The goal is to reduce deferred probes to a minimum, as it makes it very
    cumbersome to find out why a device failed to probe, and can introduce
    very big delays in when a critical device is probed.
