Overview

The Linux driver supports the PCM51xx device family of audio stereo digital-to-analog converters (DACs), communication through I2C and SPI, and registers with the ASOC framework of the Linux kernel. The "Go to third party" buttons below will allow you to downlod the appropriate drivers from git.kernal.org.

Enabling driver support

Configure kernel with "make menuconfig" (alternatively use "make xconfig" or
"make nconfig")
