The sun6i DPHY can generate several interrupts, mostly for reporting
error conditions, but also for detecting BTA and UPLS sequences.
Document this capability in order to accurately describe the hardware.

The DPHY has no interrupt number provided in the vendor documentation
because its interrupt line is shared with the DSI controller.

Fixes: c25b84c00826 ("dt-bindings: display: Convert Allwinner DSI to a schema")

I don't understand what is being fixed in that commit. That commit did
not have interrupts in D-PHY, so what was broken by it?

The Fixes tag annotates the commit which introduced a bug.

The binding had a bug because it did not accurately describe the hardware. If
you don't think this warrants a Fixes tag, I can remove it. Or are you
suggesting that the Fixes tag should instead reference the commit adding the
original .txt binding?

Yes, the latter. If original binding were not complete (although just
"incompleteness" is not really a bug, unless it is something
serious/obvious etc), then TXT commit should be the fixed one.

The backports of course will not go that deep, but Fixes tag is used
also for statistics which kernel release actually brought the bug.
Therefore adjusting Fixes just for sake of backporting is not good -
messes up with statistics.


Best regards,
Krzysztof
