Subject: arm64: tegra: Remove fallback compatible for GPCDMA
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ee7863e43228a3143398dc5bbb943c9a735a8fca;p=thirdparty%2Fkernel%2Flinux.git

arm64: tegra: Remove fallback compatible for GPCDMA

Remove the fallback compatible string "nvidia,tegra186-gpcdma" for GPCDMA
in Tegra264. Tegra186 compatible cannot work on Tegra264 because of the
register offset changes and absence of the reset property.

Fixes: 65ef237e4810 ("arm64: tegra: Add Tegra264 support")
