Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.8 Thanks! [1/3] ASoC: tlv320adcx140: Add controls for PDM clk commit: 7cfa610205d95357f9eface292dc70fce7571f65 [2/3] ASoC: tlv320adcx140: Add device tree property for PDM edges commit: 75b0adbb0806a141b0b5f074cd6bd58bb9870c0d [3/3] ASoC: tlv320adcx140: Configure PDM sampling edge commit: 79fc48e41e39d7a98c5f8ae37f613d7ff9953c86 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

Add ALSA controls to configure the PDM clocks. The clocks need to be configurable to accommodate various microphones that use clocks for low power/low resolution modes to high power/high resolution modes.
