The patch ASoC: cs53l30: Fix bit shift issue of TDM mode has been applied to the asoc tree at git://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 1708796fc1053eae3dcf648669f552967c210bd2 Mon Sep 17 00:00:00 2001 From: Nicolin Chen <nicoleotsuka@xxxxxxxxx> Date: Tue, 19 Jul 2016 15:36:14 -0700 Subject: [PATCH] ASoC: cs53l30: Fix bit shift issue of TDM mode The TDM mode using PCM format now has two-bit right shift due to the format configuration in the driver. According to Figure 4-13 in the CS53L30 datasheet, using ASP_SCLK_INV = 0 and SHIFT_LEFT = 1 should be the correct combination to create one-bit right shift for the DSP type A format.
