Re: [alsa-devel] [PATCH 1/2] ASoC: add es8316 codec driver

On 5/10/17 1:16 PM, Daniel Drake wrote:

Add a codec driver for the Everest ES8316, based on code provided by David Yang from Everest Semi.

I limited the functionality to items where the vendor code was clear, and things that can be tested on the Weibu F3C (Intel Cherry Trail). As a result the initial implementation only supports running in slave mode at single speed (up to 48kHz sample rate) using I2S. HPD is not supported.
