Merge series "Adds SPI support" from Jiri Prchal <jiri.prchal@aksignal.cz>:
Moved I2C stuff to separated file, shered thingk to header file. Added SPI in separeted file. Jiri Prchal (4): ASoC: codecs: tlv320aic3x: move model definitions ASoC: codecs: tlv320aic3x: rename probe function ASoC: codecs: tlv320aic3x: move I2C to separated file ASoC: codecs: tlv320aic3x: add SPI support sound/soc/codecs/Kconfig | 16 ++++- sound/soc/codecs/Makefile | 4 ++ sound/soc/codecs/tlv320aic3x-i2c.c | 70 +++++++++++++++++++ sound/soc/codecs/tlv320aic3x-spi.c | 76 ++++++++++++++++++++ sound/soc/codecs/tlv320aic3x.c | 108 ++++++++--------------------- sound/soc/codecs/tlv320aic3x.h | 12 ++++ 6 files changed, 204 insertions(+), 82 deletions(-) create mode 100644 sound/soc/codecs/tlv320aic3x-i2c.c create mode 100644 sound/soc/codecs/tlv320aic3x-spi.c -- 2.25.1
