GPIO polarity in bindings for Freescale MXS

Hello,

Maybe I'm missing something but the MXS processors (at least i.MX23 and i.MX28) cannot 
set the polarity of the GPIOs, so shouldn't the #gpio-cells be 1?

(From Documentation/devicetree/bindings/gpio/fsl-imx-gpio.txt):

- #gpio-cells : Should be two.  The first cell is the pin number and
   the second cell is used to specify the gpio polarity:
       0 = active high
       1 = active low

Regards,
