From: Rob Herring (Arm) Date: Tue, 13 May 2025 18:40:28 +0000 (-0500) Subject: dt-bindings: crypto: fsl,sec-v4.0: Add fsl,sec-v6.0 X-Git-Tag: v6.16-rc1~206^2~32 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=768613340842dc458c72a8ff5c6d2c8f11d42a2c;p=thirdparty%2Fkernel%2Flinux.git dt-bindings: crypto: fsl,sec-v4.0: Add fsl,sec-v6.0 The fsl,sec-v6.0 binding is the same as the fsl,sec-v4.0 binding, so add it to the existing schema and drop the old .txt binding. The compatibles in the .txt binding don't match the 1 user. Follow the user for the schema.
