From 0f202f69a16b9a687911202083c37636ad73c77e Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 17 May 2019 10:27:22 -0500 Subject: dt-bindings: arm: amlogic: Move 'amlogic, meson-gx-ao-secure' binding to its own file It is best practice to have 1 binding per file, so board level bindings should be separate for various misc SoC bindings.
