From 0114330e7f92ae4f643fca62e6004631018f48d0 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Fri, 17 Oct 2025 15:50:46 +0200 Subject: [PATCH] arm64: dts: ti: sa67: add overlay for the ADS2 carrier The SMARC module can be used on the Kontron SMARC 2.2 Evaluation carrier (ads2). Add an overlay to enable all the devices found on the carrier and enable the corresponding peripherals of the SoC.
