Subject: [PATCH 7/8] ASoC: codecs: Add RK3308 internal audio codec driver
From: Luca Ceresoli <luca.ceresoli@...tlin.com>
Add driver for the internal audio codec of the Rockchip RK3308 SoC.
Initially based on the vendor kernel driver [0], with lots of cleanups,
fixes, improvements and removal of some features.
