+       io_domains: io-domains {
+               compatible = "rockchip,rk3288-io-voltage-domain";
+               rockchip,grf = <&grf>;

+               wifi-supply = <&vcc_18>;

I finally manage to have it running at 50Mhz in high speed mode. I
need to do more testing but could be a problem
on invalid setting on logic. I will try to send up patches
