7524 + *
7525 + * 2. This file has a number of sections for each SOC subsystem. When adding
7526 + * a new constant, find the subsystem you are working on and follow the
7527 + * name pattern. If you are adding another typedef for your interface, please,
7528 + * place it with other typedefs and function prototypes.
7529 + *
7530 + * 3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
