+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.
