PCM6240 driver implements a flexible and configurable setting for register and filter coefficients, to one, two or even multiple PCM6240 Family Audio chips. Signed-off-by: Shenghao Ding <shenghao-ding@ti.com> --- Change in v3: - All these chips have only a portion of the codec's functionality, such as ADC or DAC, and so on, but their audio performance is far superior to the codec's, and cost is lower than codec, and much easier to program than codec. - remove unused data structure. --- sound/soc/codecs/pcm6240.h | 237 +++++++++++++++++++++++++++++++++++++ 1 file changed, 237 insertions(+) create mode 100644 sound/soc/codecs/pcm6240.h
