show the SMBus 2.0 clock output parameters when the
SoC controller is the SMBus Master, and when it is an I

C-bus Specification and User Manual, Rev.
03 specifications. As a master, the SoC controllers comply with all other timing
parameters defined by the specifications.
As an SMBus 2.0 or I

C Target, each SoC controller conforms to the timing parameters
defined by the specifications.
