The patch ASoC: Mediatek: MT8183: change supported formats of DL2 and UL1 has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. 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 7fa5782d5355bad773a7c9b341fcb4f712cf8352 Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih <tzungbi@xxxxxxxxxx> Date: Mon, 8 Apr 2019 18:47:28 +0800 Subject: [PATCH] ASoC: Mediatek: MT8183: change supported formats of DL2 and UL1 DL2 and UL1 are for BTSCO. They should only provide 16-bit, mono, 8kHz and 16kHz to userspace. Change the formats accordingly.
