In the earliest design, mclk is turned on in set_config() and never turned off. The behavior is modified in this commit: d5840a9 ("ssp: move mclk request/release to pre_start and post_stop") Now the mclk is enabled only during audio streaming so some codec may pop. This commit adds the always-on behavior back as an new feature. Signed-off-by: Brent Lu <[email protected]> (cherry picked from commit 8dfc008)
