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 drivers/soundwire/stream.c | 4 +- include/linux/soundwire/sdw.h | 8 +- include/sound/cs42l42.h | 5 + sound/soc/codecs/Kconfig | 8 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cs42l42-sdw.c | 603 +++++++++++++++++++++++++++++++++ sound/soc/codecs/cs42l42.c | 127 ++++--- sound/soc/codecs/cs42l42.h | 9 +- 8 files changed, 716 insertions(+), 50 deletions(-) create mode 100644 sound/soc/codecs/cs42l42-sdw.c
