    ARM: tegra: gr2d is not backwards-compatible · 46d36c40

    The instantiation of gr2d in Tegra114 is not backwards-compatible with
    the version found on earlier chips. While the hardware IP is identical,
    the compatible string also describes the integration of the IP, which
    in the case of Tegra114 is slightly different in that it's part of the
    HEG power partition, whereas it wasn't previously.
    
    Drop the misleading compatible string so that drivers that support the
    older integrations cannot match on it. Since they wouldn't be able to
    control the power partition, such driver wouldn't be able to access any
    of the registers of the IP.
