Trying to understand `gpio-line-names` change in am335x-boneblack.dts

I’m trying to understand a line in the am335x-boneblack.dts file, specifically a gpio-line-names entry:

"P8_42A [ecappwm0]",

On the schematic (REV C3), I see ECAP0_IN_PWM0_OUT on ball C18, which looks to be GPIO0_7, which looks to be P9_42. And since this pin can be in/out I landed upon P9_42A.

I then dug into the history of am335x-boneblack.dts, and I found where originally the file had P9_42A that was changed to P8_42A. See attached image:

So my questions:

  • Was this just a typo on this commit?
  • If not, could someone explain to me how P8_42A relates to ecappwm0?
