Subject: arm64: tegra: Add Jetson AGX Thor Developer Kit support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f369289d46e7d8c2335c218f5d0ddf417e8fec4d;p=thirdparty%2Fkernel%2Fstable.git

arm64: tegra: Add Jetson AGX Thor Developer Kit support

Add basic support for the Jetson AGX Thor Developer Kit. It's quite
similar to the existing reference platform but has a slightly different
carrier board with different mass storage options and I/O.
