   28       Warning, the GPIO phandle flags are ignored and the GPIO polarity is
   29       controlled solely by the presence of "enable-active-high" DT property.
   30       This is due to compatibility with old DTs.

   41       On operating systems, that don't support reading back gpio values in
   42       output mode (most notably linux), this array provides the state of GPIO
   43       pins set when requesting them from the gpio controller. Systems, that are
   44       capable of preserving state when requesting the lines, are free to ignore
   45       this property.

   47         1: HIGH
