Hello
You could find photos at http://kernel.montjoie.ovh/gemini/
There are also photos of another SL3516 SoC based device (a SSI 1328 NAS), but
I fail to setup a serial on it, so I keep it for later.

No change, probably due to all pinctrl-gemini 40000000.syscon:pinctrl: could
not map pin config for "R8 GMAC0 RXDV"
Please see http://kernel.montjoie.ovh/gemini/bootlog6.txt , I have added some
pr_info in gmac.
I have put in the directory, the final dtb which I use.
The vendor source could be found at
https://www.edimax.com/edimax/mw/cufiles/files/download/OpenSourceCode/transfer/Wireless/NAS/NAS-GPL-source.zip

I hope too.
Note that I have also started to work on the gemini crypto driver.
Thanks for your help
