The current code is for some reason not aligned with internal documentation and hardware recommended flows, specifically for multi-link operation. Changes since v1: Removed log in is_clock_stop(), use the helper in the main clock_stop() and change return 1->return 0. Fixed squash issue in patch5 to remove irrelevant udelay() change Added Patch17 to clear FIFOs and avoid pop noise Pierre-Louis Bossart (12): soundwire: cadence: s/update_config/config_update soundwire: cadence: handle error cases with CONFIG_UPDATE soundwire: cadence: mask Slave interrupt before stopping clock soundwire: cadence: merge routines to clear/set bits soundwire: cadence: move clock/SSP related inits to dedicated function soundwire: cadence: make SSP interval programmable soundwire: cadence: reorder MCP_CONFIG settings soundwire: cadence: enable NORMAL operation in cdns_init() soundwire: cadence: remove PREQ_DELAY assignment soundwire: cadence: remove automatic command retries soundwire: cadence: commit changes in the exit_reset() sequence soundwire: cadence: multi-link support Rander Wang (4): soundwire: cadence: simplifiy cdns_init() soundwire: cadence: add interface to check clock status soundwire: cadence: add clock_stop/restart routines soundwire: cadence: fix a io timeout issue in S3 test randerwang (1): soundwire: cadence: clear FIFO to avoid pop noise issue on playback start drivers/soundwire/cadence_master.c | 282 ++++++++++++++++++++++++----- drivers/soundwire/cadence_master.h | 9 +- drivers/soundwire/intel.c | 2 +- 3 files changed, 249 insertions(+), 44 deletions(-) base-commit: 0b43fef979b4664d51a09dc7e0c430ebb2d18267 -- 2.20.1
