Emit debug messages from clockdomain layer


Linux Kernel Configuration
└─>TI OMAP Implementations
└─>Emit debug messages from clockdomain layer
In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
Say Y here if you want to compile in clockdomain layer
debugging messages for OMAP2/3. These messages can
provide more detail as to why some clockdomain calls
may be failing, and will also emit a descriptive message
for every clockdomain register write. However, the
extra detail costs some memory.
