You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

This patch modify rsnd_dai_of_node() to parse "rcar_sound,dai" and "ports" (or "port") as phase 1. It can detect graph base style, but do nothing at this point.
