I've been working with hardware that is similar to the SABRESDB iMX6 board.
My next step is to redefine a few interfaces that are custom to my board.
For starters, I'd like to just tweek my GPIO configuration, by undoing some of
the GPIO setup that was used by SABRESDB and establish my own GPIO
configuration based on my schematic.
Maybe I'm just tired, or maybe this is just hard...
I'm not having much luck figuring out how to modify the .dts files that are used with
the sabresd board.
I'm currently reading the Documentation/devicetree stuff and A Tutorial on the Device Tree (Zynq) -- Part I .
Is there any other examples or good documentation that discusses this?
