Subject: [PATCH v2 1/4] ASoc: PCM6240: Create PCM6240 Family driver code
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@...com>
---
Change in v2:
- All these chips have only a portion of the functionality of codec,
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.
