Add ADAU1978/ADAU1979 audio ADCs
This adds the ADAU1978 and ADAU1979 Audio ADCs from Analog Devices. They share the pinout, the measurement voltage range is different between the devices. The inputs are labelled slightly differently in the datasheet (AINxP/AINxN
vs. AINx/~{AINx}
).
- I chose to place
DVDD
on the bottom right, as it is a power output generated from the chip, only requiring bypassing. - SPI functions (instead of I2C) are implemented using alternate pin functions
