It's okay. The gpio-latch probe function seems to be called before the
rb91x-key probe, but it also returns  EPROBE_DEFER (-517), so it will
be called later. I've tested master with reset key patch and Koen's
patch that sets ref clock freq to 25000000. All is working: nand,
leds, key and Gigabit Ethernet (setting 100 -- pings okay, setting
back 1000 -- pings still okay).

Should I delete from my rb91x-key patch support for kernel 5.4 and submit v2?
