[PATCH v3] ASoC: tas2783: Add source files for tas2783 driver.

Add source file and header file for tas2783 soundwire driver. Also update Kconfig and Makefile for tas2783 driver.

Signed-off-by: Baojun Xu baojun.xu@ti.com --- Change in v3: - change spelling for description in sound/soc/codecs/Kconfig. - add select REGMAP_SOUNDWIRE for TAS2783 in Kconfig. - remove delay.h, device.h, of_gpio.h, interrupt.h - change array tas2783_cali_reg to fixed size. - add data port registers area in tas2783_readable_register. - add comments for volatile register(reset). - change comment for volume get. - change all private struct variable name to tas_priv. - add description for why have calibration data in UEFI. - remove firmware data save. - add left, right channel setting after firmware load. - move pm_runtime functions to driver from component probe. - move firmware request to driver from component probe. - change name to component from codec. - change firmware binary name to tas2783-x.bin. - remove start_addr in struct tas2783_firmware_node. - remove firmware_node, codec in struct tasdevice_priv. - remove TAS2783_MAX_NO_NODES define. --- sound/soc/codecs/Kconfig | 14 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas2783-sdw.c | 857 +++++++++++++++++++++++++++++++++ sound/soc/codecs/tas2783.h | 100 ++++ 4 files changed, 973 insertions(+) create mode 100644 sound/soc/codecs/tas2783-sdw.c create mode 100644 sound/soc/codecs/tas2783.h
