[PATCH 00/16] SoundWire: cadence: add clock stop and fix programming sequences

[Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>]

To make progress with SoundWire support, this patchset provides the
missing support for clock stop modes, and revisits all Cadence Master
register settings. The current code is for some reason not aligned
with internal documentation and hardware recommended flows,
specifically for multi-link operation.

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
