From 0963766bc665769aebf370d44ee3a97facfbca57 Mon Sep 17 00:00:00 2001 From: Maksim Kiselev Date: Sat, 5 Aug 2023 21:05:03 +0300 Subject: [PATCH 09/14] ASoC: sunxi: sun4i-codec: add basic support for D1 audio codec Allwinner D1 has an audio codec similar to earlier ones, but it comes with 3 channel ADC instead of 2, and many registers are moved. Add basic support for it.
