Subject: [PATCH 206/224] dt-bindings: clock: mediatek: update audsys
|
|
documentation to adapt MFD device
|
|
|
|
The MediaTek audio hardware block that exposes functionalities that are
|
|
handled by separate subsystems in the kernel. These functions are all
|
|
mapped somewhere at 0x112xxxxx, and there are some control bits are mixed
|
|
up with other functions within the same registers.
|
|
|
|
This patch modifies example to illustrate child nodes.
