> If macros of numeric pinmux addresses is used, we don't need to see AM335X's Technical Reference Manual again and again to find out the meaning of each pinmux address, just check "am33xx.h". Besides, it helps us to configure module pin's for different device trees easily. For example of mii, If we want to configure module of mii pin, we check module in "am33xx.h" can pick register names we want to modify. It's hard to remember pin address number for the specific module to us.

Aha, ok, having more boards like this certainly explains the
benefits. Thanks for an explanation.

I have applied patches, I'll run some basic tests and push the
results.
