Are you sure this is GPIO_ACTIVE_HIGH?

If so, then it would need the 'enable-active-high' property.

Same here.

I think you meant to say:

interrupts-extended = <&gpio1 6 IRQ_TYPE_LEVEL_HIGH>,
      <&intc 0 119 IRQ_TYPE_LEVEL_HIGH>;
fsl,err006687-workaround-present;

Are you sure it is GPIO_ACTIVE_HIGH? if so, it would need a
reset-gpio-active-high property.

Most likely this should be:

reset-gpio = <&gpio2 21 GPIO_ACTIVE_LOW>;
