Ethernet somehow works with devicetree changes from [1], but have packets loss and strange pinctl messages in dmesg.

PA0 pin defined only in gmac_rgmii_pins group. Tried Linux kernel 6.4.12 and 6.6.1 built with sunxi_defconifg

Stock firmware have no issues.

Ah, I also configured NFC in my devicetree, so NAND flash chip now accessible.
