From 3757be5a6aa7b4ea5c748af7f68e101c3cc73aa6 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 2 Apr 2024 11:09:08 -0500 Subject: [PATCH] arm: dts: k3: Remove unneeded ti, sci-sysreset binding and nodes This extra binding is non-standard and now unneeded as we bind the sysreset driver automatically. This matches what is done in Linux and allows us to more closely match the DTBs. Remove the binding and all users.
