Say Y here to enable the imx8ulp pinctrl driver
This provides a simple pinctrl driver for i.MX8ULP SoC familiy.
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.
