Similarly PC20 and PH11, PC21 and PH12, PC22 and PH13. Also, Pins PI10 to PI19 are marked with eint. I did not try to read a datasheet, yet, so this could be dumb question, but still, I would like to know the reason... Anyway, as I am working with Orange Pi boards, I think this is not relevant for me, I am looking in h3_padconf.c and h3_r_padconf.c, it looks like all pins from PA, PG and PL blocks are usable as interrupt source... and I see no such double usage here.
