I would say if the hardware is used in GPIO mode, i.e. if the hardware
registers of the GPIO block is written to activate the LED, then it
is "LED1".

If there would be a specific LED driver block that disables the GPIO
block to be used for the same lines and have its registers elsewhere,
it would be "[LED1]".

So proper names "FOO" is for the case where the GPIO output is
used as GPIO.
