    Subject[PATCH 5.3 131/140] net: phy: bcm7xxx: define soft_reset for 40nm EPHY
    Date
    From: Doug Berger <opendmb@gmail.com>

    [ Upstream commit fe586b823372a9f43f90e2c6aa0573992ce7ccb7 ]

    The internal 40nm EPHYs use a "Workaround for putting the PHY in
    IDDQ mode." These PHYs require a soft reset to restore functionality
    after they are powered back up.

    This commit defines the soft_reset function to use genphy_soft_reset
    during phy_init_hw to accommodate this.

    Fixes: 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
