From: Bard Liao <bardliao(a)realtek.com>
This patch adds the ALC286 codec driver.
Signed-off-by: Bard Liao <bardliao(a)realtek.com>
---
This is the initial codec driver of ALC286.
I tested Headset recording and Speaker playback.
I tested with snd_soc_register_codec because my kernel doesn't support devm_snd_soc_register_codec yet.
