Subject: [PATCH 117/146] ASoC: dt-binding: Add bindings for Allwinner A64
|
|
codec's analog path controls
|
|
|
|
The internal codec on Allwinner A64 is split into 2 parts. The
|
|
analog path controls are routed through an embedded custom register
|
|
bus accessed through the PRCM block just as on A23/A33/H3.
|
|
|
|
Add a binding for this hardware.
