Subject: [PATCH 10/14] ASoC: sunxi: Add new driver for Allwinner D1/T113s
|
|
codec's analog path controls
|
|
|
|
The internal codec on D1/T113s is split into 2 parts like the previous
|
|
ones. But now analog path controls registers are mapped directly
|
|
on the bus, right after the registers of the digital part.
|
|
|
|
Add an ASoC component driver for it. This should be tied to the codec
|
|
audio card as an auxiliary device.
|
