Subject: [PATCH v5] sound/soc/lapis: add machine driver for ML7213 Carrier Board
This machine driver is for LAPIS Semiconductor ML7213 Carrier Board.
Signed-off-by: Tomoya MORINAGA <tomoya.rohm@...il.com>
---
V5
- Add channe_map function
- Use error macro (e.g. -ENOMEM) not negative integer value
- Add clock configuration for codec
