+* Freescale General-Purpose Media Interface (GPMI)
+
+The GPMI nand controller provides an interface to control the
+NAND flash chips. We support only one NAND chips now.
+
+The GPMI nand controller required properties:
+ - compatible : should be "fsl,<chip>-gpmi-nand"
+ - reg : should contain registers location and length.
+ - interrupts : should contain the DMA interrupt number for GPMI.
+ We do not use the GPMI interrupt.
+ - dma_channel: Should contain the dma channel it uses.
+
+The BCH required properties:
+ - compatible : should be "fsl,<chip>-bch"
+ - reg : should contain registers location and length.
+ - interrupts : should contain the BCH interrupt.
+
+Examples:
+
+gpmi-nand at 8000c000 {
+ compatible = "fsl,imx28-gpmi-nand";
+ reg = <0x8000c000 2000>;
+ interrupts = <88>;
+ dma_channel = <4>;
+};
+bch at 8000a000 {
+ compatible = "fsl,imx28-bch";
+ reg = <0x8000a000 2000>;
+ interrupts = <41>;
+};
