[alsa-devel] [PATCH v3 0/4] Add NXP AUDMIX device and machine drivers
by Viorel Suman 26 Jan '19

26 Jan '19

The patchset adds NXP Audio Mixer (AUDMIX) device and machine drivers and related DT bindings documentation. Changes since V2: 1. Moved "dais" node from machine driver DTS node to device driver DTS node as suggested by Rob. Changes since V1: 1. Original patch split into distinct patches for the device driver and DT binding documentation. 2. Replaced AMIX with AUDMIX in both code and file names as it looks more RM-compliant. 3. Removed polarity control from CPU DAI driver as suggested by Nicolin. 4. Added machine driver and related DT binding documentation.

[alsa-devel] [PATCH] ASoC: core: Allow soc_find_component lookups to match parent of_node
by Charles Keepax 25 Jan '19

25 Jan '19

For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device. As such when looking up components in soc_find_components we should match against both the devices of_node and the devices parent's of_node, as is already done in the rest of the ASoC core. This causes regressions for some DAI links at the moment as soc_find_component was recently added as a check in soc_init_dai_link.

An open-coded error path in __snd_pcm_lib_xfer() can be replaced with the simple goto to the common error path.
