[PATCH 2/4] dt-bindings: clock: mediatek: add clock controllers of MT7988

From: Daniel Golle <daniel@makrotopia.org>
Date: 2023-11-13 21:12:36
Also in: linux-arm-kernel, linux-clk, linux-devicetree, linux-mediatek, lkml
Subsystem: common clk framework, networking drivers, open firmware and flattened device tree bindings, the rest · Maintainers: Michael Turquette, Stephen Boyd, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Add various clock controllers found in the MT7988 SoC to existing
bindings (if applicable) and add files for the new ethwarp, mcusys
and xfi-pll clock controllers not previously present in any previous
MediaTek SoC.
