Say Y here to enable the Vybrid (vf610) pinctrl driver
This provides a simple pinctrl driver for Vybrid SoC familiy,
vf610. This feature depends on device tree
configuration. This driver is different from the linux one,
this is a simple implementation, only parses the 'fsl,pins'
property and configure related registers.
