+Freescale MPC512x LocalPlus Bus FIFO (called SCLPC in the Reference Manual)
+
+Required properties:
+- compatible: should be "fsl,mpc512x-lpbfifo";
+- reg: should contain the offset and length of SCLPC register set;
+- interrupts: should contain the interrupt specifier for SCLPC; syntax of an
+ interrupt client node is described in interrupt-controller/interrupts.txt;
+- dmas: should contain the DMA specifier for SCLPC as described at
+ dma/dma.txt and dma/mpc512x-dma.txt;
+- dma-names: should be "rx-tx";
+
+Example:
+
+ sclpc@10100 {
+ compatible = "fsl,mpc512x-lpbfifo";
+ reg = <0x10100 0x50>;
+ interrupts = <7 0x8>;
+ dmas = <&dma0 26>;
+ dma-names = "rx-tx";
+ };
