Please don't just add nonsense fixes tags for the sake of it, this just
creates noise and gets in the way of people trying to use the tags to
work out if thy need fixes.  The commit you're mentioning doesn't even
contain any changes to the binding document.

These clearly aren't pins you're adding, digital microphones use PDM
and carry a stereo pair on a single physical pin (which is what should
be and already is in the bindings).  This is adding an extra set of pins
to the binding duplicating the existing ones.

I'd expect these to be just PDM1 and PDM2, assuming that that's what the
pins are called in the chip datasheet.
