[PATCH v12] ASoC: tas2781: Add tas2781 driver
Create tas2781 driver.
Signed-off-by: Shenghao Ding 13916275206@139.com
--- Changes in v12: - Add comment on why use be32_to_cpup instead of be32_to_cpu - Simplify the code in tasdevice_add_config - Correct the wrong spelling comments in tasdevice_add_config - remove unneeded page switch in the i2c broad-cast mode, all the pagings are handled inside regmap Changes to be committed: modified: sound/soc/codecs/Kconfig modified: sound/soc/codecs/Makefile new file: sound/soc/codecs/tas2781-dsp.c new file: sound/soc/codecs/tas2781-dsp.h new file: sound/soc/codecs/tas2781-i2c.c new file: sound/soc/codecs/tas2781.h --- sound/soc/codecs/Kconfig | 13 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas2781-dsp.c | 1829 ++++++++++++++++++++++++++++++++ sound/soc/codecs/tas2781-dsp.h | 181 ++++ sound/soc/codecs/tas2781-i2c.c | 1606 ++++++++++++++++++++++++++++ sound/soc/codecs/tas2781.h | 156 +++ 6 files changed, 3787 insertions(+) create mode 100644 sound/soc/codecs/tas2781-dsp.c create mode 100644 sound/soc/codecs/tas2781-dsp.h create mode 100644 sound/soc/codecs/tas2781-i2c.c create mode 100644 sound/soc/codecs/tas2781.h
