This is kind of interesting and relates to my question about naming groups and
functions of GPIO pins.
Here we see four pins suspiciously named "GP_*" which I read as
"generic purpose"
and they are not muxed to *any* function, yes pulled up.
I would have expected something like:
keys_pins: keys-pins {
groups = "GP_5_17_grp", "GP_5_20_grp", "GP_5_22_grp", "GP_2_1_grp";
function = "gpio";
pins = "GP_5_17", "GP_5_20", "GP_5_22", "GP_2_1";
bias-pull-up;
};
I hope this illustrates what I see as a problem in not designing in
GPIO as an explicit
function, I get the impression that these pins are GPIO because it is hardware
default.
