[PATCH v2 0/2] ASoC: sdm845: fix soundwire stream handling

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

 



Recent addition of SoundWire stream state-machine checks in linux-next
have shown an existing issue with handling soundwire streams in codec drivers.

In general soundwire stream prepare/enable/disable can be called from either
codec/machine/controller driver. However calling it in codec driver means
that if multiple instances(Left/Right speakers) of the same codec is
connected to the same stream then it will endup calling stream
prepare/enable/disable more than once. This will mess up the stream
state-machine checks in the soundwire core.

Moving this stream handling to machine driver would fix this issue
and also allow board/platform specfic power sequencing.

Changes since v1:
	- removed false error check while setting sruntime.
