I only meant for the GPIO based connection, that it looks like SPI bitbanging.

I guess the question then becomes if that's an appropriate thing to do 
as part of a change set intended only to add DT bindings to an existing 
driver.  It wouldn't remove much code since much of the bit-banging type 
code still needs to remain to support the MMIO mode.

The chip does explicitly support a SPI type connection, but I'm unaware 
of any boards using it with a real SPI controller.
