Actually I don't know what "ipg" stands for. It's a quite common name on i.MX 
platforms though. I opted for the names currently used in the DT. The driver 
doesn't care for the names currently.
But cross-checking the reference manual these clocks seems to be called "jpeg" 
and "ips", individually for both jpeg encoder and decoder.
Mirela (added to recipients): As the original author of the DT nodes, could 
you provide additional information regarding the clock names?

Best regards,
Alexander
