Sorry, if it means "we define big-endian as default settings, and user can select little-endian by using sh-eth,edmac-little-endian" then, it is nice.

I meant that I could find "sh-eth,edmac-endian" operation, but, couldn't find "sh-eth,endian" operation on sh_eth_parse_dt() and on Example either. Best regards --- Kuninori Morimoto
