The TLV320ADC3001/3101 have an internal DSP, which can either be used in various preset configurations (called "Processing Blocks" in the data sheet), or as a freely programmable (using the "PurePath Studio" graphical programming tool from TI) but rather small DSP ("miniDSP").
Using the default configuration (PRB_R1) it's possible to set up filtering using a first-order IIR, which can be useful for adding a digital high pass filter to the signal chain, for instance.

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
