    Subject[PATCH v6 35/52] memory: tegra: Add missing latency allowness entry for Page Table Cache
    Date
    The PTC memory client misses the latency allowness entry and this patch
    adds it.

    This prevents erroneous clearing of MC_INTSTATUS 0x0 register during
    of the LA programming in tegra_mc_setup_latency_allowance() due to the
    missing entry. Note that this patch doesn't fix any known problems.
