So here add the GPIO > get_direction() support only for the IP which has Port Data > Direction Register (PDDR). just a question about how things work: fsl,imx7ulp-gpio and i.MX93 have PDDR, so GPIO get_direction is handled in gpio-vf610 driver fsl,vf610-gpio doesn't have PDDR, so all GPIO direction stuff is handled in pinctrl-vf610 driver Is this correct?
