I don't think just having the buttons numbered sequentially
is the best course of action, but this preserves the GPIO
ordering while other options don't...
I'm thinking about either having them named after
their function, or named after what they're labeled
on the PCB of the device.
Can any of DT maintainers give their input on this?

Is it unused? If it is I think it would belong to patch that would add
panel to this device

I'm wondering if this should be changed to 115200 baud rate
so it would end up the same as on other devices,
like Odroid Go Advance.

The physical button is labeled "F", so maybe this should be "F"
too?

I don't think just having the buttons numbered sequentially
is the best course of action, but this preserves the GPIO
ordering while other options don't...
I'm thinking about either having them named after
their function, or named after what they're labeled
on the PCB of the device.
Can any of DT maintainers give their input on this?

Is it unused? If it is I think it would belong to patch that would add
panel to this device

I'm wondering if this should be changed to 115200 baud rate
so it would end up the same as on other devices,
like Odroid Go Advance.

The physical button is labeled "F", so maybe this should be "F"
too?
