commit 25175c806a6841149abe46168e0af12593141612
Author: Thierry Reding <treding@xxxxxxxxxx>

    clk: tegra: Reimplement SOR clock on Tegra124
    
    In order to allow the display driver to deal uniformly with all SOR
    generations, implement the SOR clocks in a way that is compatible with
    Tegra186 and later.
