It should be working since v5.9, thus applicable to linux-5.10.y (longterm) and the two
newer stable branches. As I described it before, I'd drop it from linux-4.19.y
and linux-4.14.y (unless 3edfb7bd76bd from 4.20 is planning to be backported to
it, which I don't think so).
The only branch which needs to adapt this patch is linux-5.4.y (use msmgpio).
I can send a patch for it during this week.
Kind regards,
