The patch ASoC: rsnd: fix DALIGN register for SSIU has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4 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 ef8e14794308a428b194f8b06ad9ae06b43466e4 Mon Sep 17 00:00:00 2001 From: Nilkanth Ahirrao <anilkanth@xxxxxxxxxxxxxx> Date: Thu, 21 Nov 2019 12:10:23 +0100 Subject: [PATCH] ASoC: rsnd: fix DALIGN register for SSIU MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The current driver only sets 0x76543210 and 0x67452301 for DALIGN. This doesnâ??t work well for TDM split and ex-split mode for all SSIU. This patch programs the DALIGN registers based on the SSIU number.
