Hm.. this patch came to life about 1.5y ago so it's hard to tell..
Grepping for 3dmerge I found that there is some legacy reset sequence
which should not be executed for anything >=8150 (probably related
to the intf te moving), but currently it's only evaluated in
disp/dpu1/dpu_encoder.c : dpu_encoder_get_topology(). Interestingly
enough, that legacy reset sequence is not implemented upstream, so
there was really no way to hit it..
Downstream has a has_3d_merge_reset flag for that and I'm not sure
how relevant the check we have upstream in dpu_encoder is to anything
newer than 845.
While testing on PDX213 is near impossible (the panel is acting up
and only initializes once in like 10 boots, otherwise it comes to life
after $random minutes; this is a panel-specific issue though..), Luca
reported no regressions after settings this to false on his Fairphone 4.

Yes, but 7180 should be fixed up too, as the downstream dt
entry for both is identical:
qcom,sde-dspp-pcc = <0x1700 0x00040000>;
(7180 sets version to 0x1000 upstream as of now)

It's.. complicated.. With just this patch, display refreshes, albeit
not at 60fps. Marijn is working on getting it going, though

2 bytes ;)
On a more serious note, I really don't, 7180 was made with TSMC and 6350 with
"foundry ID 3" (as per socinfo on my device), if that's Samsung or some other
fab, maybe they had to make some changes. Or wild erratas.
