	  System Control and Power Interface (SCPI) Message Protocol is
 | 
						|
	  defined for the purpose of communication between the Application
 | 
						|
	  Cores(AP) and the System Control Processor(SCP). The MHU peripheral
 | 
						|
	  provides a mechanism for inter-processor communication between SCP
 | 
						|
	  and AP.
 | 
						|
 | 
						|
	  SCP controls most of the power managament on the Application
 | 
						|
	  Processors. It offers control and management of: the core/cluster
 | 
						|
	  power states, various power domain DVFS including the core/cluster,
 | 
						|
	  certain system clocks configuration, thermal sensors and many
 | 
						|
	  others.
 | 
						|

	  If your firmware supplies the HCDP table, and you want to

 | 
						|
 | 
						|
	  Neither the PCDP nor the HCDP affects naming of serial devices,
 |

	  so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
 | 
						|
	  on how the driver discovers devices.
 |
