thank you for reviewing this!
I just realized that I forgot to CC the linux-gpio mailing list as
well as Linus Walleij on this patch (fixing that with this mail) -
sorry for that.
right now this patch is applied to linux-amlogic.git's v5.1/dt branch.
please let me know whether you would like to keep it in your tree or
if you would like me to re-send it (including Linus and the linux-gpio
list this time...)
Regards
Martin
