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 86666c083a4eacb798754f2485bbecfedc9fc7d7 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Mon, 10 Apr 2017 12:35:11 -0700 Subject: [PATCH] ASoC: Improve hi6210-i2s DT bindings This patch improves the previously submitted hi6210-i2s DT binding, adding extra details to how the multi-dai index value maps to the potential interfaces. (Currently just index 0 -> the S2 interface, as there is only one supported, but in the future other interfaces may be enabled.)
