I attached a version for the new driver which you can pick instead. Thanks, Daniel

[alsa-devel] [PATCH 0/2] slimbus: Add QCOM SLIMBus NGD driver
by Srinivas Kandagatla 23 May '18

23 May '18

This patchset adds support to basic version of Qualcomm NGD SLIMBus controller driver found SoCs from B family. This controller is light-weight SLIMBus controller driver responsible for communicating with slave HW directly over the bus using messaging interface, and communicating with master component residing on ADSP for bandwidth and data-channel management. Tested this patchset on DB820c with WCD9335 codec. I have pushed my working branch to [1] incase someone want to try.

[alsa-devel] sound: ALSA PCM Timestamps
by Muni Sekhar 23 May '18

23 May '18

[ Please keep me in CC as I'm not subscribed to the list] Hi All, There are several time stamping functions in ALSA: snd_pcm_status_get_trigger_tstamp snd_pcm_status_get_trigger_htstamp snd_pcm_status_get_tstamp snd_pcm_status_get_htstamp snd_pcm_status_get_audio_htstamp snd_pcm_status_get_driver_htstamp I would like to understand what points in time the resulting functions represent and what is the corresponding kernel mode callback for those API’s. I'd be really grateful if someone took the time to help me clearing my doubt. -- Thanks, Sekhar

[alsa-devel] Applied "ASoC: rockchip: cdn-dp sound output use spdif" to the asoc tree
by Mark Brown 23 May '18

23 May '18

The patch ASoC: rockchip: cdn-dp sound output use spdif has been applied to the asoc tree at https://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.
