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.
