Add source file and header file for tas2783 driver. Update Kconfig and Makefile for tas2783 driver.

Signed-off-by: Baojun Xu baojun.xu@ti.com

--- Change in v2: - change all registers access to regmap. - change header file include order. - remove tas2783_sdw_read(). - remove regmap_bus and relative function. - change custom access to regmap. - return if get calibration data from EFI failed. - remove mutex protect for null function. - remove tasdevice_startup() as no actions needed. - remove sysclk function as no action needed. - remove tasdevice_mute(). - remove crc8 look up table generate. - remove first_hw_init flag. - change some define name to TAS2783_XXX. - remove SMS_HTONL(), use le_to_cpup(). - remove enum channel define. - change struct and element name for FW. - remove global address elements. - remove irq and gpio in structure. - remove tasdevice structure. --- sound/soc/codecs/Kconfig | 12 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas2783-sdw.c | 872 +++++++++++++++++++++++++++++++++ sound/soc/codecs/tas2783.h | 113 +++++ 4 files changed, 999 insertions(+) create mode 100644 sound/soc/codecs/tas2783-sdw.c create mode 100644 sound/soc/codecs/tas2783.h
