From: Ashish Mhetre Date: Mon, 27 Apr 2026 07:34:18 +0000 (+0000) Subject: dt-bindings: memory: tegra: Add nvidia,tegra238-mc compatible X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bf7cf25d4245fe49c71eba0e3b09b6260a336999;p=thirdparty%2Flinux.git dt-bindings: memory: tegra: Add nvidia,tegra238-mc compatible Document the device tree binding for the Tegra238 memory controller. Tegra238 has 8 memory controller channels plus broadcast and stream-id registers. Add the stream ID header (nvidia,tegra238-mc.h) defining ISO and NISO stream IDs for SMMU configuration.
