This mostly seems to be a sun4i/sun7i vs sun5i thing. mmc1 could be routed through PH on sun4i/sun7i, but actually is never used there, as PH typically is used for gpio purposed on sun4i/sun7i, where as on sun5i (which has way less pins), mmc1 goes out on PG, and actually is used as such there. I have considered keeping the old pinmux settings using #if defined SUN5I for the new ones, but since the old ones are never used just replacing them seems better. Regards, Hans
