Subject: memory: tegra: Add missing latency allowness entry for Page Table Cache
X-Git-Tag: v5.11-rc1~90^2~21^2~14
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d5ecac0afa30811901eb401067f196e688aeb73e;p=thirdparty%2Flinux.git

memory: tegra: Add missing latency allowness entry for Page Table Cache

Add missing PTC memory client latency allowness entry to the Tegra MC
drivers.

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.
