[PATCH v2] ASoC: dt-bindings: renesas,rsnd: add post-init-providers property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



At least if rsnd is using DPCM connection with Audio-Graph-Card2,
fw_devlink might doesn't have enough information to break the cycle
(Same problem might occur with Multi-CPU/Codec or Codec2Codec).
In such case, rsnd driver will not be probed.
Add post-init-providers support to break the link cycle.
