Hi Thomas,
Commit 2233bf7a92e7 ("gpio: mvebu: switch to regmap for register
access") in next-20170607 breaks gpio-keys on an armada-385 (Linksys
WRT3200ACM), noticed due to missing /dev/input/event0 and the below
dmesg output.
# dmesg -l 0,1,2,3
[ 2.421130] genirq: Setting trigger mode 3 for irq 49 failed (mvebu_gpio_irq_set_type+0x0/0x168)
[ 2.429953] gpio-keys gpio-keys: Unable to claim irq 49; error -22
After reverting the offending commit all works again.
Ralph

I found the bug and I've just sent a fix for it (use the v2 as the first
version was wrong).
Thanks for the report,
Gregory
