    memory: tegra: Support DVFS on Tegra186 and later · 52d15dd2
    Thierry Reding authored
    Add a Tegra186 (and later) EMC driver that reads the EMC DVFS tables
    from BPMP and uses the EMC clock to change the external memory clock.
    
    This currently only provides a debugfs interface to show the available
    frequencies and set lower and upper limits of the allowed range. This
    can be used for testing the various frequencies. The goal is to
    eventually integrate this with the interconnect framework so that the
    EMC frequency can be scaled based on demand from memory clients.
