From: Peter Ujfalusi Date: Fri, 13 Dec 2024 10:11:22 +0000 (+0200) Subject: ASoC: SOF: Add support for pause supported tokens from topology X-Git-Tag: v6.14-rc1~24^2~13^2~46^2~1 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=70a667d70cce338ab8552dd762ae114a5ab96500;p=linux-block.git ASoC: SOF: Add support for pause supported tokens from topology New tokens are added to topology: 1202: SOF_TKN_STREAM_PLAYBACK_PAUSE_SUPPORTED 1203: SOF_TKN_STREAM_CAPTURE_PAUSE_SUPPORTED The new tokens are used to advertise support for PAUSE/RESUME operation on a PCM device depending on firmware product, use case, pipeline topology. The snd_sof_pcm_stream.pause_supported is updated to reflect the advertised value for the PCM device. If the token does not exist then the pause_supported is set to false. Note: it is up to the platform code to use this flag to decide to advertise the PAUSE support for user space or not.
