+NXP i.MX eLCDIF (Enhanced LCD Interface)
+========================================
+Required properties:
+- compatible: should be "fsl,imx8mm-lcdif"
+- reg: should be register base and length as documented in the
+  datasheet.
+- interrupts, interrupt-names: Should contain interrupts and names as
+  documented in the datasheet.
+- interrupt-parent: contains the phandle to IRQ Steer module.
+- clocks, clock-names: phandles to the LCDIF clocks described in
+  Documentation/devicetree/bindings/clock/clock-bindings.txt
+- assigned-clocks, assigned-clock-parents, assigned-clock-rate: configure
+  LCDIF related clock sources, clock source parents and clock source rates.
+- lcdif-gpr: a phandle which provides the LCDIF control and gpr registers
+  configuration.
+Optional properties:
+- port@0: Port nodes with endpoint definitions as defined in
+  Documentation/devicetree/bindings/media/video-interfaces.txt.
+  ports 0 should correspond to display interface 0.
+
+example:
+       lcdif: lcdif@32E00000 {
