[PATCH 10/13] arm64: dts: broadcom: northstar2: Rework clock nodes
Rob Herring (Arm)
robh at kernel.org
Tue Jan 6 18:09:49 PST 2026
The nd2-clocks.dtsi is oddly included in the middle of a bus node and is
only included in one place, so collapse it into ns2.dtsi. Move the fixed
and fixed-factor clock nodes to the root as they are not part of the
bus. Rename the node names to use preferred names.
