-Subject: [PATCH] workaround-s3c24xx-i2s-stop-live-stream-stall-on-resume.patch
- Reported-by: Graeme Gregory <graeme@openmoko.org>
- Basically-solved-by: Graeme Gregory <graeme@openmoko.org>
-
-Graeme found a while back that on resume, IISCON register in
-s3c2442 does not show LRCK toggling in LRINDEX bit any more,
-causing s3c24xx_snd_lrsync() to timeout and return an error,
-aborting restart of any live stream that was playing at
-suspend.
-
-I confirmed it was true, meddled around for a bit looking
-for some magic to restart LRCK or at least the reporting of
-it, and in the end worked around it using the method noted
-by Graeme: just ignore LRCK sync if it timed out. The worst
-that could happen would be L and R swap for the duration of
-stream that was suspended into but probably not even that.
