Hi Valentine,

Thanks you for the patch.

Given the wide variety of ways the VIN data pins can be used, I see two ways 
to group them:

- List all possible combinations of data pins with a single group per 
configuration. There are 11 combinations, but due to overlap in the pins used 
the number can be reduced to 8.

- List groups individually and combine them to create a valid configuration. 
We would have at least 8 groups in this case as well.

Given that the number of groups would be identical, my preference would go for 
the first solution. The RGB data pin group would contain all 24 RGB pins in 
that case, and additional overlapping groups would be defined for other input 
configurations. Would you be fine with that ? VIN1 would be handled 
identically, and VIN2 would need 5 groups only. VIN3 is already defined 
correctly, as it supports a single configuration only.

I think you can drop _signal here and below.

If I'm not mistaken the hsync and vsync signals can't be used independently, 
so they should be grouped together.

I'm only adding missing stuff here. VIN0/VIN1 are identical so I'm adding VIN1
the same way VIN0 is currently grouped.
I'm generally fine with re-grouping data pins, but I think it should be a separate change.
We'd also need to choose simple names for the groups which are easily readable and show
which pins are used there. Something like:
data_r07g07b07 (24 bits for RGB24)
data_r27g27b27 (pins 2-7 for ITU-R BT.601/BT.709 RGB-666)

I didn't intend to edit the existing naming. All I wanted to do is add the definitions
for the missing pins here. I think name editing should be done by a separate patch if needed.
IMHO, otherwise it would be a mess.

I'm just using the current VIN0 layout for VIN1 here.
I'm not intending to regroup anything here. The purpose of these
changes is to add missing pins. I believe regrouping should be done
by a separate patch if needed.

Renaming pin groups can be an issue if they are used by existing platforms, so 
I'd rather first think about the way pins should be grouped, fix the existing 
code if needed, and then adding the new groups. Would that be fine ?

Sure, but could you then please send patches that drop _signal and group 
hsync+vsync, and rebase this patch on top of that ?

OK, I'll take a look at that, but I don't see much of a point in adjusting the names
and modifying/rebasing this patch on top of that.
I think that would just involve more work, while eventually having the same result.
I was planning to regroup the pins and rename the groups on top of this one.

Thanks,
Val.
