| * Freescale General-Purpose Media Interface (GPMI) |
| |
| The GPMI nand controller provides an interface to control the |
| NAND flash chips. We support only one NAND chip now. |
| |
| Required properties: |
| - compatible : should be "fsl,<chip>-gpmi-nand" |
| - reg : should contain registers location and length for gpmi and bch. |
| - reg-names: Should contain the reg names "gpmi-nand" and "bch" |
| - interrupts : The first is the DMA interrupt number for GPMI. |
| The second is the BCH interrupt number. |
| - interrupt-names : The interrupt names "gpmi-dma", "bch"; |
| - fsl,gpmi-dma-channel : Should contain the dma channel it uses. |
| |
| The device tree may optionally contain sub-nodes describing partitions of the |
| address space. See partition.txt for more detail. |
| |
| Examples: |
| |
| gpmi-nand@8000c000 { |
| compatible = "fsl,imx28-gpmi-nand"; |
| #address-cells = <1>; |
| #size-cells = <1>; |
| reg = <0x8000c000 2000>, <0x8000a000 2000>; |
| reg-names = "gpmi-nand", "bch"; |
| interrupts = <88>, <41>; |
| interrupt-names = "gpmi-dma", "bch"; |
| fsl,gpmi-dma-channel = <4>; |
| |
| partition@0 { |
| ... |
| }; |
| }; |
