    Subject[PATCH v2 4/4] ARM: dts: tegra20: Revert "Fix ULPI regression on Tegra20"
    Date
    Commit 4c9a27a6c66d ("ARM: tegra: Fix ULPI regression on Tegra20") changed
    "ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is
    the parent of CDEV2 clock and original clock setup of "ulpi-link" was
    correct. The reverted patch was fixing USB for one board and broke the
    other, now Tegra's clk driver correctly sets parent for the CDEV2 clock
    and hence patch could be reverted safely, restoring USB for all of the
    boards.
