    SubjectRe: [PATCH v2 05/21] ARM: tegra: clock: Disable clocks left on by bootloader

    I would argue that any kernel functionality that relies on clocks
    being left on my bootloader is buggy, and/or should at least have
    those clocks enabled in the static clock tables for the boards in
    question, since it creates an undocumented dependency on firmware.

    I would prefer if it disabled the clocks by default (after warning),
    but that there was a runtime way to override while debugging (i.e. add
    a bootarg 'keep_fwclocks' or similar to keep the firmware-enabled
    clocks running and just warn about them).
