[PATCH 3/5] arm64: dts: ti: k3-j721s2: Add chipid node to wkup_conf bus

From: Andrew Davis
Date: Fri Nov 17 2023 - 09:09:36 EST


Like in other K3 SoCs the chipid register is inside the wakeup
configuration space. Move the chipid node under a new bus to
better represent this topology and match other similar SoCs.
