Subject: [PATCH 00/12] 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 .. #10 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 #11 and #12 actually add the Soundwire handling.

Richard Fitzgerald (12):
  ASoC: cs42l42: Add SOFT_RESET_REBOOT register
  ASoC: cs42l42: Add bitclock frequency argument to cs42l42_pll_config()
  ASoC: cs42l42: Ensure MCLKint is a multiple of the sample rate
  ASoC: cs42l42: Separate ASP config from PLL config
  ASoC: cs42l42: Use cs42l42->dev instead of &i2c_client->dev
  ASoC: cs42l42: Split probe() and remove() into stages
  ASoC: cs42l42: Split cs42l42_resume into two functions
  ASoC: cs42l42: Pass component and dai defs into common probe
  ASoC: cs42l42: Split I2C identity into separate module
  ASoC: cs42l42: Export some functions for Soundwire
  ASoC: cs42l42: Add Soundwire support
  ASoC: cs42l42: Add support for Soundwire interrupts
