The kernelci.org robot reported new boot failures in v3.19.7 on a
variety of at91 boards[1][2][3]. I instructed the robot perform a boot
bisection which yielded...

c67881fc890916206e723329e774391c6ed354ce is the first bad commit
commit c67881fc890916206e723329e774391c6ed354ce

    clk: at91: usb: propagate rate modification to the parent clk

    commit 4591243102faa8de92da320edea47219901461e9 upstream.

    The at91sam9n12 and at91sam9x5 usb clocks do not propagate rate
    modification requests to their parents.
    This causes a bug when the PLLB is left uninitialized by the bootloader
    (PLL multiplier set to 0, or in other words, PLL rate = 0 Hz).

    Implement the determinate_rate method and propagate the change rate
    request to the parent clk.

Locally I've reverted c67881fc890916206e723329e774391c6ed354ce on top
of v3.19.7 and confirmed that my at91-sama5d3_xplained boots that
kernel successfully[4].
