   4 Subject: [PATCH 206/224] dt-bindings: clock: mediatek: update audsys
   5  documentation to adapt MFD device
   6
   7 The MediaTek audio hardware block that exposes functionalities that are
   8 handled by separate subsystems in the kernel.  These functions are all
   9 mapped somewhere at 0x112xxxxx, and there are some control bits are mixed
  10 up with other functions within the same registers.

  12 This patch modifies example to illustrate child nodes.
