+         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.
