Subject: [PATCH v3 0/8] ASoC: cs42l42: Add SoundWire support

The CS42L42 has a SoundWire interface for control and audio. This
chain of patches adds support for this.

Patches #1 .. #5 split out various changes to the existing code that
are needed for adding Soundwire. These are mostly around clocking and
supporting the separate probe and enumeration stages in SoundWire.

Patches #6 .. #8 actually adds the SoundWire handling.

Changes since v1:
- fixes for various review comments from v1
- add support for wakeup from clock stop using hardware interrupts
- use port_prep callback to prepare/deprepare codec

Changes since v2:
- fix various comments
- enable pm_runtime during probe

Richard Fitzgerald (6):
  ASoC: cs42l42: Add SOFT_RESET_REBOOT register
  ASoC: cs42l42: Ensure MCLKint is a multiple of the sample rate
  ASoC: cs42l42: Separate ASP config from PLL config
  ASoC: cs42l42: Export some functions for SoundWire
  ASoC: cs42l42: Add SoundWire support
  ASoC: cs42l42: Don't set idle_bias_on

Stefan Binding (2):
  soundwire: stream: Add specific prep/deprep commands to port_prep
    callback
