Subsystem:
open firmware and flattened device tree bindings, spi subsystem, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Mark Brown, Linus Torvalds
These two properties were not documented but used in the spi dts. Add the related documentation. Suggested-by: Krzysztof Kozlowski <redacted> Signed-off-by: Andi Shyti <redacted> Reviewed-by: Michael Turquette <mturquette-rdvid1DuHRBWk0Htik3J/w@public.gmane.org> Reviewed-by: Krzysztof Kozlowski <redacted> --- Hi, Changelog related only to this patch: V1 -> V2: [new] added the clocks and clock-name documentation in the bindings V2 -> V3: reworded the 'clock-names' as suggested by Krzysztof, added Mike's and Krzysztof's review and Krzysztof's suggested-by.
