[PATCH v4 3/5] dt-bindings: clock: imx8mp: Add audiomix block control
From: Marek Vasut <marex@denx.de>
Date: 2023-02-23 17:11:45
Also in:
linux-clk, linux-devicetree
Subsystem:
common clk framework, nxp i.mx clock drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Abel Vesa, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Unlike the other block control IPs in i.MX8M, the audiomix is mostly a
series of clock gates and muxes. Add DT bindings for this IP.
