How to configure MX28_PAD_GPMI_D00__GPMI_D0 as GPIO

Hello,

 

We are not using GPMI Nand on our imx28 board and want to use MX28_PAD_GPMI_D00__GPMI_D0 as GPIO.

 

Can this be completely configured in the DTS file? If so how ?

 

I know that somewhere I need to add ,

 

fsl,pinmux-ids = <

0x0003

>

 

but am not sure where it should go.

 

Also what are the 'hog_pin_a' used for ?

I see that these are configured as GPIO.

 

I have been poking around the .dts files and support docs and am still quite confused.

 

Thanks for any help.

-Randy
