this patchset applies on top of "[PATCH 00/14] soundwire: intel:
implement new ASoC interfaces". It implements a series of improvements
for:
a) interrupt handling on Intel platforms in MSI mode
b) race conditions on codec probe and enumeration
c) suspend-resume issues (clock-stop mode not supported for now)
d) underflow handling
e) updates to the stream state machine which did not support valid
ALSA transitions.
These patches were tested extensively on 4 different platforms and are
viewed as required for any sort of SoundWire-based product.
Bard Liao (3):
soundwire: intel/cadence: fix timeouts in MSI mode
soundwire: stream: only prepare stream when it is configured.
soundwire: intel: reinitialize IP+DSP in .prepare()
Pierre-Louis Bossart (15):
soundwire: fix race between driver probe and update_status callback
soundwire: bus: add PM/no-PM versions of read/write functions
soundwire: bus: write Slave Device Number without runtime_pm
soundwire: intel: add helpers for link power down and shim wake
soundwire: intel: Add basic power management support
soundwire: intel: add pm_runtime support
soundwire: intel: reset pm_runtime status during system resume
soundwire: bus: add helper to reset Slave status to UNATTACHED
soundwire: intel: call helper to reset Slave states on resume
soundwire: bus: check first if Slaves become UNATTACHED
soundwire: add enumeration_complete signaling
soundwire: intel: disable pm_runtime when removing a master
soundwire: bus: disable pm_runtime in sdw_slave_delete
soundwire: stream: update state machine and add state checks
soundwire: stream: do not update parameters during DISABLED-PREPARED
