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.

Also there is no any "TX", "RX" dma-names entries in arch/arm/boot/dts, only lower case "tx", "rx" seem to be used. Lastly, this driver doesn't set SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag when registering a dmaengine PCM to indicate the chan_name should be used. My intention is to eventually remove the struct snd_dmaengine_dai_dma_data chan_name field as there is also a chan_names[] field in struct snd_dmaengine_pcm_config which can be used for same purpose.
