[PATCH v9 1/6] dt-bindings: clock: Add spread spectrum definition
From: Peng Fan (OSS) <hidden>
Date: 2026-03-12 06:57:27

arm-scmi, linux-clk, linux-devicetree, lkml
Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
From: Peng Fan <peng.fan@nxp.com> Per dt-schema, the modulation methods are: down-spread(3), up-spread(2), center-spread(1), no-spread(0). So define them in dt-bindings to avoid write the magic number in device tree.
