[alsa-devel] [PATCH v4 00/17] ASoC: fsl-ssi: Driver cleanup

This series is a cleanup of the fsl-ssi driver.

v4 includes the changes I made to fix the baudclock handling. I moved the
baudclock enable/disable function calls into hw_params()/hw_free(). To avoid
inconsistent reference counters for the baudclock I use a variable
baudclk_streams which describes the active streams to be able to decide if
we have to enable/disable the clock and set the rate. I currently don't have a
board to test i2s-master, maybe I am able to test it next week. The new patch
which includes these changes is "ASoC: fsl-ssi: Fix baudclock handling".

Best regards,


Changes in v4:
 - New patch to fix baudclock handling (enable/disable/set_rate)

Changes in v3:
 - Some new patches to improve/fix i2s master mode by Sascha
 - baudclock is enabled/disabled in startup/shutdown now
 - bitclock setup moved to a seperate function (not set_dai_sysclk)
 - Regmap config changed to NATIVE now.
