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
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
ASoC: cs42l42: Wait for debounce interval after resume
