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. Thanks, Mark From 4d4b334bda47f1b7b57f7aca9bc19b7e317d764d Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 18 May 2017 01:28:06 +0000 Subject: [PATCH] ASoC: rsnd: add support graph base DT phase 2 To enable OF-graph base DT on rsnd driver, and to keep compatible previous normal sound card style, it need to support both "rcar_sound,dai" and "ports" (or "port") on DT. This patch parses both style.
