need help in fixing: Cudy WR1300 v2 5GHz wifi led not working - mt7613

I'm trying to get the WR1300 v2 LED (5GHz) to work but haven't had any success so far. (the 2.4GHz led of the mt7603 is working fine)

I tried setting the led_pin in /sys/kernel/debug/ieee80211/phyx/mt76 and I also tried libgpiod/gpiod-tools for testing GPIOs (sadly only character device version 1 is supported so far)
gpiod-tools didn't make any of the LEDs light up, I hope that's just cause other gpios are already claimed/in use by the kernel (because they were set in the dts) and not because this method doesn't work

other mt7613 define their led outside of the pcie node as a normal led node (or not at all). are these just special cases or is the mt7615/mt7663 firmware not able to control mt7613 LEDs, yet? (because mt7615 already has some led code, that I'm sure of, but maybe just for dbdc or regular mt7615 and not mt7613?)

Start by reproducing the 5GHz LED issue on the Cudy WR1300 v2 and inspect the mt76 debug path at /sys/kernel/debug/ieee80211/phyx/mt76. Compare the reported mt7613 behavior with the existing mt7615 LED handling and the device-tree LED definitions. Done means determining the supported control path and making the 5GHz LED work, with the result verified on this hardware.
