linux-clk, linux-devicetree
Subsystem:
common clk framework, nxp i.mx clock drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Stephen Boyd, Brian Masney, Jerome Brunet, 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.
