+ 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
