Enable PTP pins on the MAC0

I would like to have the PTP clock available on one of the pins of the SC589.

 

I'm working on the SC589-EZ kit.  I have seen the ptp could be routed to the pins eg. GPIO_PB1 (physical pin AC19) where I can use the clock in hardware through the U49 clock component.

 

I adapted the sc589-ezkit.dts file as enclosed, hoping this would route the available pins to the output.

I've added the pinctrl-1 line in the emac0 block.

I've also created a new block eth0_ptp in the pinctrl definition.

 

What Am I doing wrong ? Am I making some syntax error ?

Should I enable those pins in the driver as well ?
