From fcb97d190c3ca411b37d8dd0b2650fa1378f08d4 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 5 Dec 2023 10:23:58 -0600 Subject: [PATCH] arm64: dts: ti: k3-am65: Add AM652 dtsi file The AM652 is basically a AM654 but with 2 cores instead of 4. Add a DTSI file for AM652 matching AM654 except this core difference. This removes the need to remove the extra cores from AM654 manually in DT files for boards that use the AM652 variant. Do that for the IOT2050 boards here.
