This set of patches adds handling for system suspend.
Patches 1..4 make some code changes that simplify the
suspend implementation, mainly to avoid race conditions.

There are two seperate aspects to suspend, and these have
been done as two patches:
- the main suspend-resume handling,
- re-loading the firmware if necessary after resume.

Richard Fitzgerald (6):
  ASoC: cs35l56: Remove quick-cancelling of dsp_work()
  ASoC: cs35l56: Use DAPM widget for firmware PLAY/PAUSE
  ASoC: cs35l56: Skip first init_completion wait in dsp_work if
    init_done
  ASoC: cs35l56: Always wait for firmware boot in runtime-resume
  ASoC: cs35l56: Add basic system suspend handling
  ASoC: cs35l56: Re-patch firmware after system suspend

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
