IPG/PER clocks

Hi !

I've tried to search for the meaning of the 'IPG' acronym that one can find in several reference manual or in Linux source code, but I can't find a source. What does 'IPG' stands for ?

 

Also, I'm trying to fully understand the differences between the 'ipg' and 'per' clocks that most device have (for in Linux dtb). My understanding is that the 'ipg' clock drives the access to the device iomapped registers, and the 'per' clocks drives the device itself.

 

Am I right ?

 

Thank your for your explanation,

V.
