I think the outstanding comments shouldnt last more than 1-2 revs more 
on this one as its mostly due to multiple patches on the list touching 
catalog at the same time. I have been monitoring the comments closely 
even though I dont respond to all of them.

One of the major reasons of the number of issues with DSC 1.1 was QC 
didn't really have the devices or panels to support it. Thats why I 
changed that this time around to take more control of validation of DSC 
1.2 and ofcourse decided to break up of series into the least amount of 
functionality needed to keep the DPU driver intact.

All that being said, we still value your comments and would gladly wait 
for a couple of days like I already wrote. But there are more 
incremental series on top of this:

-> DSI changes for DSC 1.2
-> proper teardown for DSC
-> DSC pair allocation support
-> DSC 1.2 over DP

We will be posting all of these within next couple of weeks on top of this.

Ack. the intent is always to do things right the first time.
